Solar industry guidance

The guidance on this page complements information in our Notice to Market, which sets out the mandatory requirements and recommendations for retailers and installers to participate in the Solar Homes program.

Use this guidance along with our Solar PV Audit Checklists and Battery Audit Checklist to ensure installations under our program are compliant and meet the high standards we have set.

Legislation and regulations

Commonly identified legislation and regulations within the solar industry include:

A full list of legislation and regulations related to the solar industry is listed on the Energy Safe Victoria and WorkSafe Victoria websites.

Compliance codes and codes of practice also play an important role. They explain your duties or obligations under legislation in practical ways that are aimed to help you comply.

See WorkSafe compliance codes and codes of practice and ESV electrical technical guidelines and determinations.

Australian Standards

Installers in our solar programs must adhere to current and relevant standards for the design and installation of solar and battery storage systems.

These are made mandatory through:

legislation and/or regulations; and/or
normative reference from a mandated standard (commonly AS/NZS 3000 – Wiring Rules); and
are required by the Solar Victoria Notice to Market

Penalties for failing to meet Australian Standards vary. Solar Victoria may suspend or cancel an installer or retailer from its programs for non-compliance. See Installer terms and conditions and Retailer terms and conditions.

Commonly identified AS/NZS Standards within the solar industry include, but are not limited to:

AS/NZS 1170 Series	Structural Design Actions(All parts)
AS 1768	Lightning Protection
AS/NZS 3000	Electrical Installations (known as Wiring Rules)
AS/NZS 4509 Series	Stand-alone power systems Part 1: Safety and installation Part 2: System design
AS/NZS 4777 Series	Grid Connections of Energy Systems via Inverters Part 1: Installation Requirements Part 2: Inverter Requirements
AS/NZS 5033	Installation of photovoltaic (PV) arrays
AS/NZS 5139	Electrical installations – Safety of battery systems for use with power conversion equipment

Guidance

Industry guidance informs retailers and installers of leading practice. It may be voluntary in nature or made mandatory through the Solar Victoria Notice to Market.

Energy Safe Victoria, WorkSafe Victoria and Solar Victoria develop guidance to inform installers and retailers of non-compliances found within installations.

The following solar industry guidance plus installation guidance news can be found on the Energy Safe Victoria website:

How to ensure you have a compliant PV installation.

Technical solution and guidance sheets

Series 1: Working safely at height

We developed this series of technical solution sheets in collaboration with WorkSafe Victoria to help installers in our program work safely in the solar industry. Use this series to plan safe systems of work while installing photovoltaic systems.

Risks increase when you are working at height, and particularly on multi-level buildings eligible through our Solar for Apartments Program. Different equipment may be used to control risk in these scenarios.

To ensure you eliminate the risk of working at height with appropriate controls in every scenario, please follow the guidance below alongside information on the WorkSafe Victoria website.

Edge protection is a passive fall prevention system used to protect workers when working at heights. It acts as a physical and visible barrier around the perimeter of a work area to help prevent employees, tools, and equipment from falling.

Manual handling is work such as manually lifting, lowering, pushing, pulling, carrying, moving or holding solar panels and other heavy and bulky items. During solar installations, injuries can occur while undertaking hazardous manual handling.

Series 2: Battery installation safety

We commissioned TechSafe Australia and Grey Sky Solar Consulting to develop a series of guidance sheets to support installers’ understanding of applicable requirements in AS/NZS 5139:2019 Electrical installations – Safety of battery systems for use with power conversion equipment.

See Battery audit checklist and guidance

Series 3: Solar PV installation safety

We commissioned Grey Sky Solar Consulting to develop a series of technical guidance sheets to support installers’ understanding of applicable requirements in:

AS/NZS 3000:2018 Electrical installations “Wiring Rules”.
AS/NZS 4777.1:2016 Grid connection of energy systems via inverters Part 1: Installation requirements.
AS/NZS 5033:2021 Installation and safety requirements for photovoltaic (PV) arrays.

See Solar PV audit checklist and guidance

Series 4: Hot water installation safety

We commissioned TechSafe Australia to develop technical guidance sheets to support installers’ understanding of the safe drainage of temperature pressure relief valves in reference to these standards, codes and regulations:

Plumbing Regulations 2018
National Construction Code volume 3
Plumbing Code of Australia
AS/NZS 3500.2:2021 Plumbing and Drainage Part 2: Sanitary Plumbing and Drainage
AS/NZS 3500.4:2021 Plumbing and Drainage Part 4: Heated Water Services

See hot water audit checklist and guidance

How to manage end-of-life solar PV

Installers and retailers in our program are required to responsibly manage solar PV and comply with the Victorian Government’s ban on e-waste entering landfill.
