Section 6: Requirements for hot water rebates

Mandatory: 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: Confirmation all workers engaged to install solar hot water systems have attained:

• CPCCWHS1001 Prepare to work safely in the construction industry accredited unit of competency (White Card/construction induction card).

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 Solar Victoria’s programs.

Mandatory: All hot water system retailers must maintain a record of all eligible systems installed under Solar Victoria’s programs. The record shall include the make, model, serial number/s, the time, date, and address of installation, for all eligible systems.

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: All authorised solar hot water retailers to provide a minimum five year whole-of-system warranty for all eligible systems under Solar Victoria’s programs (including quality of work).

Retailers must also provide the customer with documentation confirming the terms and conditions of the warranty, and who to contact in the event of a product failure.

Why:

• Solar Victoria is aiming to improve program controls to protect consumers and meet compliance requirements.
• Updates to the terms and conditions for participation in Solar Victoria’s programs requires retailers to:
  • express the warranty requirement as simply and clearly as possible
  • make a declaration when they apply to participate in the programs that they agree to provide the warranty
  • make a statement that they have provided the customer with documentation confirming the terms and conditions of the warranty and who to contact in the event of a product failure
  • state that the warranty and responsibilities, in relation to installation, continue to operate after a retailer is suspended or otherwise ceases to participate in the Solar Victoria programs.

Mandatory: Compliance with the Victorian Government's ban on electronic waste to landfill.

Why:

• Compliance with the Victorian Government's ban on electronic waste to landfill.
• 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 electro- magnetic 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, inverter an energy storage equipment.

Recommended: Hot water storage tanks should be sized in line with the following size guide.

Recommended tank size for hot water heaters:

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.

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.
