Print - Notice to Market 2026-27

Date:: 1 July 2026

Minister’s Foreword

Leading the way to home electrification with products and systems that are fit-for-purpose and future-ready, and an industry that puts customers, safety and quality first.

Victoria’s clean energy transition continues to accelerate, with renewable electricity now supplying more than 44 per cent of the state’s power at the end of 2025, well above our legislated 40 per cent target. This is a significant milestone and a clear indication that Victoria is firmly on track to reach 95 per cent renewable electricity by 2035 and Net Zero emissions by 2045.

Victorians are at the heart of this transition. Through the 10 year, $1.3 billion Solar Homes Program, more than 500,000 rebates and interest free loans have already been approved, helping households cut energy bills, electrify their homes, and contribute to a cleaner, more resilient energy system. Thousands of rooftop solar PV, energy-efficient hot water, and solar battery systems have now been installed, making Solar Homes one of Australia’s most successful sustainability programs.

Since 2018, Solar Victoria has continued to expand its programs to reach more households and support more electric homes. The Solar for Apartments Program is delivering solar access to multi-unit dwellings, while the Residential Electrification Grants Program is backing innovative projects that reduce emissions and support the growing demand for more-electric homes.

The Victorian Energy Upgrades program is also playing an increasingly important role, providing discounts on energy-efficient products that help both homeowners and renters maximise their clean energy technologies and benefit from lower bills through self-generated electricity.

Safety, quality, and consumer protection remain central to our approach. Solar Victoria, in partnership with industry and regulators, maintains the safest record for solar installations in Australia. This is achieved through strong program entry controls, rigorous standards, and a clear focus on continuous improvement. The Notice to Market sets out Solar Victoria’s expectations for product quality, installer competence, and system performance to ensure all technologies are fit for purpose and future ready.

Building the capability of the clean energy workforce is fundamental to sustaining this growth. The Victorian Government has invested $12 million, with a further $5 million committed in the most recent Budget, to train more workers and trades across safety, electrical upgrades, heat pump installation, and other priority areas. This investment is strengthening industry skills and supporting a robust, confident sector.

Victoria’s energy transition is a shared effort. Industry partners, retailers, installers, and regulators all play a vital role in delivering safe, high-quality outcomes for Victorian households. I thank our industry partners for their continued collaboration, their professionalism, and their commitment to helping deliver a cleaner, fairer, more reliable energy future for all Victorians.

Together, we are building an energy system that supports jobs, reduces emissions, and ensures Victorian households continue to benefit from the transition already well underway.

3.1 Solar PV retail business and workforce requirements

The following retail business and workforce requirements apply to all solar PV system rebates for owner-occupiers, renters and community housing. They aim to enhance safety and quality by maintaining rigorous standards and developing a level playing field within the industry.

3.1.1 Solar PV retailers – mandatory retail business requirements

Mandatory: Solar PV retailers must be a signatory to the New Energy Tech Consumer Code (NETCC) program administered by the Clean Energy Council (CEC) and maintain the status of NET Approved Seller in order to remain an authorised solar PV retailer under the Solar Homes Program.
Why:
- The NETCC replaces the Approved Solar Retailer Code of Conduct as a set of service standards and consumer protections that build on the previous Code, expanding it to new energy technology beyond solar to batteries, electric vehicle chargers and more.
- The Code requires solar PV retailers to commit to quality service and stronger consumer protections than Australian Consumer Law and the national small-scale renewable energy certificate (STC) scheme provide for.
- New signatories to the NETCC undergo a stringent application process and are subject to a monitoring, compliance, and sanctions regime.
- Becoming a NET Approved Seller and authorised solar PV retailer highlights a commitment to high standards across sales and marketing, quotes and contracts, delivery and installation, and warranties and support.
- Administered by the CEC, the NETCC was initially approved by the ACCC and is governed by an independent council of industry and consumer bodies including Energy Consumers Australia, Consumer Action Law Centre and Energy Networks Australia. Compliance with and enforcement of the code is undertaken by an independent monitoring and compliance panel.
- More information:
  - New Energy Tech Consumer Code
  - Become an authorised solar retailer or installer
Mandatory: Solar PV retailers must have no prosecutions under the Occupational Health and Safety Act 2004 and/or the Occupational Health and Safety Regulations 2017 (or equivalent legislation/ regulations in other Australian jurisdictions) resulting in a plea of guilty or a finding of guilt in the past three years.
Why:
- Compliance with relevant occupational health and safety Acts and regulations protect the health, safety and welfare of employees and other people at work.
- Confirming compliance with relevant occupational health and safety Acts and regulations aims to ensure that the health and safety of employees and the public are not put at risk by work activities.
Mandatory: Solar PV retailers must ensure they provide mandated levels of supervision of apprentice electricians under the Electricity Safety Act 1988 and the Electricity (General) Regulations 2019.
Why:
- On 1 September 2025, new requirements came into effect.
- An employer of an apprentice electrician is responsible for ensuring the quality of apprentice training, and their safety and supervision.
- Under the Electricity Safety Act and the Electricity Safety (General) Regulations, apprentice electricians are only deemed licensed to carry out electrical installation work when working under effective supervision and with a training contract under the Education and Training Reform Act.
- For more information and to download the Apprentice Supervision Requirements, see: Requirements for the effective supervision of apprentice electricians | Energy Safe Victoria.
Mandatory: Solar PV retailers must confirm that all their workers engaged to install solar PV systems have attained:
- CPCWHS1001 Prepare to work safely in the construction industry accredited unit of competency (White Card/construction induction card, previously obtained CPCCWHS1001 Prepare to work safely in the construction industry accredited unit of competency is still valid).
- VU23631 Work safely on roofs with renewable energy systems unit certification (previously obtained VU22744 Work Safely in the Solar industry accredited unit of competency is still valid).
See Work safely in the solar industry
Why:
- Retailers are responsible for ensuring workers are appropriately trained to perform high-risk work.
- Retailers must perform due diligence to ensure all workers meet the regulated and contractual requirements of participating in the Solar Homes Program.
Mandatory: Solar PV retailers must confirm that all their workers engaged to install systems have successfully completed training and/or mentoring as required by Solar Victoria from time to time.
Why:
- Training and mentoring mandated by Solar Victoria is/will be industry validated and customised for the solar industry in consultation with subject matter experts.
- Training and mentoring mandated by Solar Victoria will be available to complete prior to the mandatory completion date set by Solar Victoria for each module.
- Solar Victoria will provide reasonable notice of mandatory training and/or mentoring on its website at Training and workforce development.
Mandatory: Solar PV retailers, or parties acting on behalf of the retailer, must not conduct sales of eligible systems as part of the Solar Homes program using door-to-door or telemarketing sales techniques.
The ban:
- prohibits ‘cold-call’ telemarketing and door-to-door sales techniques to all types of consumers
- prohibits telemarketing and door-to-door sales to prospective or previous customers from being outsourced to contractors or marketing companies
- only permits marketing or sales calls at the request of the consumer or with their express permission, and only within three months or a timeline specified when the consumer opts into calls, and only in accordance with the New Energy Tech Consumer Code
- permits calls to notify a previous customer of a product default or recall that affects them.
Why:
- This protects consumers, particularly vulnerable cohorts, from persistent, unsolicited or nuisance calls and pressure sales tactics.
- This prevents contacting consumers who are listed on the ‘Do Not Call Register’.
- This aligns with the Victorian Energy Upgrades program marketing ban administered by the Essential Services Commission.
- This prevents reputational harm to the Solar Homes Program by being associated with nuisance telemarketing and door-to-door marketing techniques.
Note: the telemarketing prohibition came into effect under the Solar Homes program on 1 May 2024 and door-to-door sales prohibition commenced on 1 September 2021 via the Retailer Terms and Conditions (see Instruction issued 30 April 2024).
Mandatory: Solar PV retailers must maintain a record of all eligible solar PV systems installed under the Solar Homes Program. The record shall include the make, model, serial numbers, the time, date, and address of installation, for each system.
The records must be made available to Solar Victoria upon request.
Why:
- To proactively assist original equipment manufacturers (OEMs), regulators, and government bodies in the event of a product safety recall or other related product issue.
- To enable tracking of where products are located for the purpose of end-of-life management.
Mandatory: Solar PV retailers must provide solar PV system customers with a financial performance estimate.
Why:
- Typically, customers purchase solar PV systems to reduce their electricity bills. However, under current Australian Standards, customers are only required to receive an electricity performance estimate with no consideration of estimated cost savings.
- Greater transparency of the financial benefits of installing solar PV systems empowers customers to make informed decisions.
Mandatory: Solar PV retailers are responsible for removing replaced solar PV systems, or system components (for example, PV panels, inverters and cabling) from the premises, unless expressly requested not to do so by the customer.
Why:
- The Victorian Government banned e-waste from entering landfill in Victoria, effective 1 July 2019.
- Retailers are best placed to manage the appropriate removal of solar PV systems.
- Applies to the retailer who is providing the new system.
- For more information, see How to manage end of life Solar PV.
Mandatory: Solar PV retailers must comply with the Victorian Government's ban on electronic waste to landfill.
Why:
- The Victorian Government has banned e-waste from landfill in Victoria, effective 1 July 2019. E-waste is growing three times faster than general municipal waste in Australia, and it contains both valuable and hazardous materials that can be recovered when they reach the end of their working life.
- The Waste Management Policy (e-waste) was approved by the Executive Council on 26 June 2018 and gazetted on 28 June 2018. The Victorian Government Gazette e-waste order can be found on pages 1457 to 1463.
- E-waste describes any device which requires an electromagnetic current (including anything with a plug, cord or battery) to operate and includes all solar products at the end of their useful life i.e. panels, inverters and energy storage equipment.
- More information, see Managing e-waste.
Mandatory: Solar PV retailers must provide a minimum five year whole-of-system warranty for all eligible systems, including any solar sharing technology, under the Solar Homes Program (including quality of work).
The warranty commencement date is to be the date the system is handed over to the customer.
Retailers are responsible for ensuring that products are procured and installed so that product warranties are not voided.
The customer must not be required to pay upfront nor incur any expenses associated with a successful warranty claim, including:
- parts or materials
- labour
- inspections or tests to investigate, support or prove the claim
- freight, transport, insurances or customs clearances
- removal, installation or re-installation
- disposal.
Retailers must also provide the customer with documentation confirming the terms and conditions of the whole-of-system and product warranties, and who to contact in the event of a system or product failure.
The system must be serviced as per the product manufacturer’s requirements to maintain the warranty.
This warranty is in addition to any customer guarantees that apply automatically under the Australian Consumer Law.
Why:
- Solar Victoria is aiming to improve program controls to protect consumers and meet compliance requirements.
- This supports the terms and conditions for retailers to participate in Solar Victoria programs.
- For more information on consumer guarantees and warranties, visit Consumer Affairs Victoria.

3.1.2 Solar PV retailers – recommendations for retail business

Recommended: Solar PV retailers should be registered with Energy Safe Victoria as a Registered Electrical Contractor.
Why:
- Where a solar PV retailer is also a Registered Electrical Contractor the entity is subject to the Electrical Safety Act 1998. Registered Electrical Contractors are obliged to provide Certificates of Electrical Safety to parties for whom electrical work is carried out.
- Registration as a Registered Electrical Contractor places greater responsibility on the retailer to ensure worker and customer safety.
Recommended: The main business location of the solar PV retailer should be listed as “Victoria” according to the Australian Government’s Australian Business Register.
Why:
- A key element of the Solar Homes Program concerns driving job creation with strong local content and industry development to build local supply chains. Prioritising businesses with a main business location of Victoria contributes to achieving this.
Recommended: Solar PV retailers should confirm that workers engaged to install solar PV systems have attained 22657VIC Working Safely on Rooftop Renewable Energy Systems (previously obtained 22515VIC Course in Working Safely in the Solar Industry is still valid).
See Work safely in the solar industry.
Why:
- Retailers have a responsibility to ensure workers are appropriately trained to perform high-risk work.
- Working Safely on Rooftop Renewable Energy Systems is an accredited training program and provides vocational outcomes for persons wishing to gain the skills and knowledge required for the safe installation of solar PV systems.
- Training content includes VU23631 Work safely on roofs with renewable energy systems (a training unit developed and customised for the solar industry), White Card/construction induction training, first aid and working at heights.
Recommended: Solar PV retailers should confirm all their workers engaged to install solar PV systems have attained CPCCCM2012 (or RIIWHS204) Work Safely at Heights accredited unit of competency.
See Work safely in the solar industry.
Why:
- Retailers are responsible for ensuring workers are appropriately trained to perform high-risk work.
- This training sets out the requirements to work safely on construction sites where the work activity involves a risk of a person falling more than 2 metres and where fall protection measures are required.
- Completion of Work Safely at Heights training is a work health and safety risk control measure.
Recommended: Solar PV retailers should complete training pertaining to whole-of-system design and/or systems thinking.
Why:
- Energy solutions today aren’t just about solar panels—they’re part of a bigger picture. Homes are electrifying, products are becoming smarter, and systems are more connected than ever.
- Retailers and installers need to think beyond individual components and design solutions that work together seamlessly.
Recommended: To comply with the Victorian Government's ban on electronic waste to landfill under the Environment Protection Regulations 2021 (EP regulations), solar PV retailers should keep records and evidence of ‘lawful place’ disposal during replacement of solar PV systems, or system components (for example, PV panels, inverters and cabling).
Why:
- The Victorian Government banned e-waste from entering landfill in Victoria, effective 1 July 2019.
- Retailers are best placed to manage the disposal of solar PV systems.
- A producer of waste must take all reasonable steps to ensure that the waste is received at a ‘lawful place’ authorised to receive that type of waste in order to comply with the ban.
- Documenting the disposal of solar PV systems demonstrates compliance with the EP regulations.
- For more information about ‘lawful place’, see the Environment Protection Authority Victoria website.
Recommended: Solar PV retailers should offer end-of-life management programs, during replacement or disposal, with service provider/s certified to AS/NZS 5377.
Why:
- The Solar Homes Program aims to support Victoria’s emerging circular economy by encouraging best practice approaches and outcomes for solar PV products and materials at the end of their lifecycle.
- AS/NZS 5377 establishes Australia’s best practice benchmark for the collection, storage, transport and treatment of end-of-life electrical and electronic equipment.
- Solar Victoria recognises the national stewardship approach underway for solar PV products and materials at the end of their lifecycle.
- See How to manage end-of-life solar PV.
Recommended: Prior to completing commissioning, solar PV retailers should advise the customer of the benefits of properly maintaining and servicing their solar PV system.
If requested by the customer, retailers should provide information on their solar PV system servicing offering.
Servicing should only be performed by a licenced electrician who holds active Solar Accreditation Australia Grid Connected Photovoltaic Systems (GCPV) installer accreditation, and as a minimum include panel cleaning, visual inspection, electrical safety checks and testing, and performance testing.
The frequency should be based on site-specific factors such as local weather and environmental conditions, and the service history, but typically should not be at intervals greater than every 2 years.
Why:
- Regular servicing of the solar PV system helps to maximise the amount of electricity it generates, extend the lifespan of the panels and system components, and maintain warranties by:
  - ensuring the panels are operating at peak efficiency
  - identifying and addressing potential issues early, like damage, corrosion, or loose connections, before they become major problems
  - checking the system is safe and functioning correctly.
- For information for customers, see How to clean and maintain solar panels.
Recommended: Solar PV retailers should advise customers of the Victorian Energy Compare website and to use the solar saver tool prior to installing a solar PV system.
Why:
- The Victorian Energy Compare website is a Victorian Government initiative that includes a solar savings calculator using NMI (National Metering Identifier) specific data.
- The solar calculator can be used by homeowners to compare the proposed solar PV system to their actual usage and tariff structure.
- Solar Victoria refers customers to the Victorian Energy Compare website to calculate how much money they could save on energy bills by installing solar panels. This includes via our:
  - Householder e-newsletter

Why:
- Participation in this initiative:
  - makes it easier for manufacturers/importers to upload serial number data to the ledger
  - gives installers onsite confirmation of a solar panel's eligibility
  - helps agents to create STCs
  - enables CER to process STC claims faster.
Recommended: Solar PV retailers should ensure that customers are provided with an electronic customer record confirming installed solar PV modules are verified as part of the industry-led SPV Initiative.
Why:
- Validation via this initiative provides customers with an electronic record that confirms their installed solar PV modules are verified as part of the initiative.
- The record includes information such as the make and model of the solar PV modules, serial numbers, the time and date of installation and the location.
Recommended: Solar PV module manufacturers should provide a performance warranty that panels will deliver 90 per cent production at 10 years and 80 per cent at 25 years.
The warranty commencement date should be the date the system is handed over to the customer.
Why:
- This supports customers to receive high quality products that do not suffer from a significant drop in production over their lifetime.

Section 4: Requirements for hot water rebates

This section lists requirements that retailers and installers, systems and products must satisfy under the hot water rebate. It also includes recommendations.

4.1 Hot water retail business and workforce requirements

The following retail business and workforce requirements for hot water rebates aim to enhance safety and quality by maintaining rigorous standards and developing a level playing field within the industry.

4.1.1 Hot water retailers – mandatory retail business requirements

Mandatory: Hot water retailers must have no prosecutions under the Occupational Health and Safety Act 2004 and/or the Occupational Health and Safety Regulations 2017 (or equivalent legislation/regulations in other Australian jurisdictions) resulting in a plea of guilty or a finding of guilt in the past 3 years.
Why:
- Compliance with relevant occupational health and safety Acts and regulations protect the health, safety and welfare of employees and other people at work.
- Confirming compliance with relevant occupational health and safety Acts and regulations aims to ensure that the health and safety of employees and the public are not put at risk by work activities.
Mandatory: Hot water retailers must ensure they provide mandated levels of supervision of apprentice electricians under the Electricity Safety Act 1988 (Vic) and the Electricity (General) Regulations 2019 (Vic).
Why:
- On 1 September 2025, new requirements came into effect.
- An employer of an apprentice electrician is responsible for ensuring the quality of apprentice training, and their safety and supervision.
- Under the Electricity Safety Act and the Electricity Safety (General) Regulations, apprentice electricians are only deemed licensed to carry out electrical installation work when working under effective supervision and with a training contract under the Education and Training Reform Act.
- For more information and to download the Apprentice Supervision Requirements, see Requirements for the effective supervision of apprentice electricians | Energy Safe Victoria.
Mandatory: Hot water retailers must confirm all their workers engaged to install solar hot water systems have attained:
- CPCWHS1001 Prepare to work safely in the construction industry accredited unit of competency (White Card/construction induction card, previously obtained CPCCWHS1001 Prepare to work safely in the construction industry accredited unit of competency is still valid).
- VU23631 Work safely on roofs with renewable energy systems training unit certification if the worker is required to carry out rooftop activities (previously obtained VU22744 Work Safely in the Solar industry accredited unit of competency is still valid).
Why:
- System retailers have a responsibility to ensure workers are appropriately trained to perform high-risk work.
- Retailers must perform due diligence to ensure all workers meet the regulated and contractual requirements of participating in the Solar Homes Program.
Mandatory: Hot water retailers must confirm that all their workers engaged to install systems have successfully completed training and/or mentoring as required by Solar Victoria from time to time.
Why:
- Training and mentoring mandated by Solar Victoria is/will be industry validated and customised for the solar industry in consultation with subject matter experts.
- Training and mentoring mandated by Solar Victoria will be available to complete prior to the mandatory completion date set by Solar Victoria.

Mandatory: Hot water retailers, or parties acting on behalf of the retailer, must not conduct sales of eligible systems as part of the Solar Homes Program using door-to-door or telemarketing sales techniques.
The ban:
- prohibits ‘cold-call’ telemarketing and door-to-door sales techniques to all types of consumers
- prohibits telemarketing and door-to-door sales to prospective or previous customers from being outsourced to contractors or marketing companies
- only permits marketing or sales calls at the request of the consumer or with their express permission, and only within three months or a timeline specified when the consumer opts into calls, and only in accordance with the New Energy Tech Consumer Code
- permits calls to notify a previous customer of a product default or recall that affects them.
Why:
- This protects consumers, particularly vulnerable cohorts, from persistent, unsolicited or nuisance calls and pressure sales tactics.
- This prevents contacting consumers who are listed on the ‘Do Not Call Register’.
- This aligns with the new Victorian Energy Upgrades program marketing ban administered by the Essential Services Commission.
- This prevents reputational harm to the Solar Homes program by being associated with nuisance telemarketing and door-to-door marketing techniques.
Note: the telemarketing prohibition came into effect under the Solar Homes Program on 1 May 2024 and door-to-door sales prohibition commenced on 1 September 2021 via the Retailer Terms and Conditions (see Instruction issued 30 April 2024).
Mandatory: Hot water retailers must maintain a record of all eligible hot water systems installed under the Solar Homes Program. The record shall include the make, model, serial number/s, the time, date, and address of installation, for each system.

- disposal.
Retailers must also provide the customer with documentation confirming the terms and conditions of the whole-of-system and product warranties, and who to contact in the event of a system or product failure.
The system must be serviced as per the product manufacturer’s requirements to maintain the warranty.
This warranty is in addition to any customer guarantees that apply automatically under the Australian Consumer Law.
Why:
- Solar Victoria is aiming to improve program controls to protect consumers and meet compliance requirements.
- This supports the terms and conditions for retailers to participate in Solar Victoria programs.
- For more information on consumer guarantees and warranties, see the Consumer Affairs Victoria website.

4.1.2 Hot water retailers – recommendations for retail business

Recommended: The main business location of the hot water retailer should be listed as “Victoria” according to the Australian Government’s Australian Business Register.
Why:
- A key element of the Solar Homes Program concerns driving job creation with strong local content and industry development to build local supply chains. Prioritising businesses with a main business location of Victoria contributes to achieving this.
Recommended: Hot water retailers should confirm all their workers engaged to install solar hot water systems have attained 22657VIC Working Safely on Rooftop Renewable Energy Systems (previously obtained 22515VIC Course in Working Safely in the Solar Industry is still valid).
See Work safely in the solar industry.
Why:
- Retailers have a responsibility to ensure workers are appropriately trained to perform high-risk work.
- Working Safely on Rooftop Renewable Energy Systems is an accredited training program and provides vocational outcomes for persons wishing to gain the skills and knowledge required for the safe installation of solar PV systems.
- Training content includes VU23631 Work safely on roofs with renewable energy systems (a training unit developed and customised for the solar industry), White Card/construction induction training, first aid and working at heights.
Recommended: Hot water retailers should confirm all their workers engaged to install hot water systems have attained, CPCCCM2012 (or RIIWHS204) Work Safely at Heights accredited unit of competency.
See Work safely in the solar industry.
Why:
- Retailers are responsible for ensuring workers are appropriately trained to perform high-risk work.
- This training sets out the requirements to work safely on construction sites where the work activity involves a risk of a person falling more than 2 metres and where fall protection measures are required.
- Completion of Work Safely at Heights training is a work health and safety risk control measure.
Recommended: Hot water retailers should complete training pertaining to whole-of-system design and/or systems thinking.
Why:
- Systems and products are becoming more complex and integrated, and so retailers and installers are required to undertake more upfront design work.
- This supports holistic thinking and futureproofing when designing and installing energy solutions as customers continue to electrify their homes.
Recommended: Hot water retailers should ensure hot water systems are offered, designed and installed as fit-for-purpose in light of a customer’s circumstances, needs and expectations and having regard to matters such as:
- hot water consumption profile
- maximising self-consumption of solar generation
- future-proofing potential changes to occupancy and household needs over time.
Why:
- Undersized units are generally less expensive upfront but need to run for longer periods to recharge the tank with hot water and may not be able to deliver hot water at the desired temperature when it is required.
- Oversized units are generally more expensive upfront, less energy efficient, and switch on and off too often (‘short cycling’) which may result in excessive wear and tear.
- Where a customer is seeking to maximise self-consumption of solar generation, the unit will need to be sized for winter conditions (daylight hours, minimum air temperatures, etc.) in Victoria.
- Hot water consumption profiles can differ significantly from customer-to-customer, for example differences in delivered volume and temperature throughout the day, and seasonal requirements.
Recommended: Hot water storage tanks should be sized in line with the following size guide:
Recommended tank size for hot water heaters:
Number of bedrooms Number of occupants Recommended tank size
1-2 1-2 150-225 litres
3 2-4 225-300 litres
4 or more 4+ More than 300 litres
Why:
- It is recommended that a hot water system should store at least 75 litres of hot water for each person living at a property. This includes some extra capacity to account for changes in consumption.
- A system that is too small for a household may mean regularly running out of hot water.
- A system that is too large for a household will cost more to buy and run.
- Recommended tank sizing from consultation provided by Renew during the creation of the Hot Water Buyers Guide.
Recommended: For hot water heat pumps, the minimum operating temperature specified on the product datasheet should be lower than the minimum recorded temperature as specified by the Bureau of Meteorology (BOM).
See BOM Climate data online.
Why:
- To ensure the hot water heat pump will not be installed outside of its operating range to prevent failures.
- To reduce the probability of hot water heat pumps being perceived as unreliable.
- The Bureau of Meteorology data is to be used because it is public data and is used by the Clean Energy Regulator (CER).
Recommended: If a hot water retailer makes a claim that a customer is likely to achieve a favourable return on investment, the retailer should provide the customer with a written financial performance estimate.
As a minimum, the estimate should be prepared on a defensible basis, use and document reasonable assumptions, and itemise the following:
- total installed cost of the eligible system prior to any incentives being applied
- each incentive being applied
- any further discounts being applied
- forecast energy savings
- anticipated servicing and maintenance costs.
Implementation of this recommendation can be achieved by providing a financial performance estimate which conforms to the financial disclosure requirements set out in the NETCC.
Why:
- Customers may purchase solar hot water systems and hot water heat pumps to reduce their energy bills.
- Greater transparency of the financial benefits and costs of installing hot water systems empowers customers to make informed decisions.
- Providing financial performance estimates supports industry-led work to develop and implement minimum energy performance standards, a key priority and recommendation of the Roadmap for Heat Pump Hot Water Systems in Australia, released in July 2024.
- For financial performance estimate guidance, see NETCC.
Recommended: Hot water retailers should offer end-of-life management programs, during replacement or disposal, with service provider/s certified to AS/NZS 5377.
Why:
- The Solar Homes Program aims to support Victoria’s emerging circular economy by encouraging best practice approaches and outcomes for hot water products and materials at the end of their lifecycle.
- AS/NZS 5377 establishes Australia’s best practice benchmark for the collection, storage, transport and treatment of end-of-life electrical and electronic equipment.
Recommended: Hot water retailers should advise customers of the Victorian Energy Compare website and how to use the solar saver tool prior to installing a hot water system.
Why:
- The Victorian Energy Compare website is a Victorian Government initiative that includes a solar savings calculator using NMI (National Metering Identifier) specific data.
- The solar calculator can be used by homeowners to compare the proposed solar PV system to their actual usage and tariff structure.
- Solar Victoria refers customers to the Victorian Energy Compare website to calculate how much money they could save on energy bills by installing solar panels. This includes via our:
  - Householder e-newsletter
  - Solar Hub(opens in a new window) including Buyers Guides
  - consumer education and customer service activities, including events.
- Victorian Energy Compare and the solar calculator can be accessed at compare.energy.vic.gov.au.

Number of bedrooms	Number of occupants	Recommended tank size
1-2	1-2	150-225 litres
3	2-4	225-300 litres
4 or more	4+	More than 300 litres

4.1.3 Hot water installers – mandatory workforce requirements

4.2 Hot water system and product requirements

The following system and product requirements apply to all hot water rebates. They aim to enhance safety and quality by maintaining rigorous standards and ensuring products are future-fit.

Products don’t need to be entirely Australian made to qualify for the higher rebate of up to $1,400. However, businesses must ensure any country-of-origin claims comply with Australian Consumer Law. Note that the ‘Australian Made’ logo is not automatically equivalent to Solar Victoria’s definition of ‘local content,’ which has its own eligibility criteria.

See Apply for listing as a hot water product with local content.

4.2.1 Hot water systems – mandatory requirements

Mandatory: Hot water units must be listed on the Solar Victoria hot water product list.
Why:
- This listing confirms solar hot water systems meet additional requirements, above minimum industry standards, to be eligible to participate in the Solar Homes Program.
Mandatory: Hot water units must be listed on the CER's register of solar hot water heaters.
Why:
- Registration with the CER confirms that such systems comply with AS/NZS 2712 and may be subject to a product certification audit and compliance regime.
- Listing is a requirement to participate in the Federal Government’s Small-scale Renewable Energy Scheme (SRES).
Mandatory: Hot water units must be listed on the Essential Services Commission's register of products.
Why:
- Registration with the Essential Services Commission confirms that such systems comply with AS/NZS 2712 and includes efficiency modelling in addition to the CER’s efficiency modelling.
- Listing is a requirement to participate in the Victorian Government’s Victorian Energy Upgrades (VEU) program.
Mandatory: Hot water systems and any in-scope connectable device required to make the system work must be compliant with the Cyber Security (Security Standards for Smart Devices) Rules 2025.
Why:
- New cyber security rules for connectable devices came into effect on 4 March 2026. The rules apply to in-scope connectable products.
- The security rules align with the first three principles of ETSI EN 303 645 and have been introduced to uplift the cyber security of consumer-grade smart devices.
- Under the new rules, manufacturers must meet obligations to uplift baseline cyber security, these include:
  - no default passwords
  - publication of a means to report security issues
  - publication of the date on which security updates will cease.
- For more information on in-scope connectable devices affected by this security standard, see Security Standards for Smart Devices.
Mandatory: Hot water heat pumps must contain refrigerants with a Global Warming Potential (GWP) less than 700 as defined in the Intergovernmental Panel on Climate Change (IPCC) version 4.
Why:
- High GWP refrigerants contribute towards climate change if released into the atmosphere at end-of-life or from leakage.
- Removal of high GWP refrigerants will contribute towards national commitments under the 2016 Kigali Amendment as well as state and national emission reduction targets.
- Restriction of products with less than 700 GWP is consistent with the Essential Services Commission product requirement for heat pump hot water systems to participate in the Victorian Energy Upgrades program.
- The GWP is defined in the Intergovernmental Panel on Climate Change (IPCC) fourth assessment report 2007 (version 4).
Mandatory: Hot water heat pumps, as a minimum requirement, must have:
- an end-user (customer or occupant) configurable integrated timer that is accessible via an external control panel or interface and allows the hot water heat pump to run between a specified time window; or,
- be connected to a solar PV system and runs the hot water heat pump during periods of solar generation.
The unit shall be capable of running outside of this time window for adequate hot water delivery, to support defrost cycles and to inhibit the growth of Legionella bacteria as per AS 3498.
These features shall be provided as part of the standard product.
Compliance with this requirement can be achieved by providing a control panel mounted on the unit or remotely, or via a wireless controller or software solution.
Why:
- This allows an end-user to optimise the heating schedule to suit their needs and circumstances, for example to seasonally adjust to maximise self-consumption of solar generation or effectively manage their tariff.
- As heat pumps operate most efficiently in warmer temperatures, timers can improve the unit's efficiency.
- Timers can reduce the probability of failures for heat pumps running in colder climates.
- Timers can reduce the likelihood of noise complaints at night while people are sleeping.
- This removes risk to human safety or damage to components from an end-user attempting to access a timer contained within the internal working of the system.
Mandatory: Hot water manufacturers must provide a minimum 5-year product warranty for all eligible hot water units under the Solar Homes Program.
The warranty commencement date is to be the date the system is handed over to the customer.
The warranty must cover all components supplied by the manufacturer, including:
- For solar hot water units:
  - Storage tank, solar collector (any component in the solar collector including, but not limited to, manifold collectors, evacuated tubes, flat plate collectors, collector frames), heat exchanger, controller, thermostat, and valves.
- For hot water heat pumps:
  - Storage tank, compressor, evaporator, condenser, expansion valve, any other component that has refrigerant, water heat exchanger, controller, thermostat, and valves.
The customer must not be required to pay upfront nor incur any expenses associated with a successful warranty claim, including:
- parts or materials
- labour
- inspections or tests to investigate, support or prove the claim
- freight, transport, insurances or customs clearances
- removal, installation or re-installation
- disposal.
The product must be serviced as per the manufacturer’s requirements to maintain the warranty.
This warranty is in addition to any customer guarantees that apply automatically under the Australian Consumer Law.
Why:
- Solar Victoria is aiming to improve program controls to protect consumers and meet compliance requirements.
- This allows retailers and manufacturers to jointly determine the most appropriate commercial arrangements to provide the required warranty coverage to the customer.
- This supports the terms and conditions for retailers to participate in Solar Victoria programs.
- For more information on consumer guarantees and warranties, see the Consumer Affairs Victoria website.

4.2.2 Hot water systems – recommendations

Recommended: Hot water heat pumps should be installed with smart controllers that support remote monitoring and control and enable end users to view hot water data via a software solution.
As a minimum, the hot water data should include delivered hot water volume, delivered hot water temperature, estimated hot water volume remaining (‘usable hot water’), electricity consumption, operating mode, periods whenever the electric booster operates (if fitted), and error codes.
Why:
- Smart controllers support the use of mobile apps to allow end users to conveniently monitor, schedule and control the unit as well as view hot water data so that they can optimise system operation, for example to reduce their bills.
- Increased data access will assist with early diagnosis of emerging performance issues with the unit.
- Smart controllers also support the integration of hot water systems with other DER, for example to optimise self-consumption of solar generation, connect to a home energy management system (HEMS), and access the internet to utilise cloud-based solutions.
- Smart controllers are a first step towards greater facilitation of DER in the network, for example the possibility to participate in future energy markets and/or flexible connection arrangements.
Recommended: The installed hot water system should include an open communication protocol.
Why:
- Open communication protocols facilitate interoperability among smart home devices, mobile apps and cloud services by avoiding the use of proprietary signals. Examples of established and emerging open protocols include BACNet, Modbus, CSIP-AUS and Matter.
- Open communication protocols support third party (e.g. aggregator, platform provider, distribution network service provider, distribution service operator, etc) visibility, communication and orchestration.
- Systems with open communication protocols may participate in future energy markets and / or flexible connection arrangements.
Recommended: Hot water manufacturers should ensure the hot water unit can deliver the remaining hot water in the tank during a power outage provided there is no interruption to mains water supply.
Why:
- During a power outage it will ensure households have access to hot water for a period for bathing and cleaning purposes.
- As households electrify, it is necessary that key appliances, such as hot water systems, can provide benefits to consumers during power outages or interruptions.
