About this audit checklist
Independent auditors for the Solar Homes Program use this checklist when inspecting solar PV system installations. For Solar for Apartments installations, auditors apply additional checklist questions that relate to wiring, switchboards and inverter power sharing devices.
This solar PV audit checklist:
- Applies only to solar PV systems installed under the Solar Homes and Solar for Apartments programs.
- Contains the questions used during audits on rebated systems. Audits are generally performed within six months of the solar PV system installation date, with a focus on safety, quality and compliance with standards.
- Is not intended to be used as a general solar PV system audit checklist for systems outside of the program or for other related services.
- Is not an installation checklist and should not be used to guide the installation of a solar PV system.
Audit ratings and what they mean
When auditors check a solar PV installation, each issue they assess is given one of the ratings below. These ratings help you understand what needs to be rectified, what improvements need to be made, and what has been done correctly.
| Rating | What it means |
|---|---|
| Unsafe | There is a serious safety hazard that poses an immediate risk to people or property. The system will be shut down until the issue is fixed and the installation is safe. |
| Needs rectification | The installation does not comply with important safety or quality requirements in the relevant standards or guidelines. While it may not be immediately dangerous, it could become unsafe if not addressed. The retailer/installer must fix the issue as a priority. |
| Improvements identified (for information) | The installation is not dangerous, but some parts do not fully meet the standards or guidelines. Improvements are recommended to bring the system up to best practice. Items do not require urgent rectification unless paired with a 'Needs rectification' or 'Unsafe' report. |
| Adequate | No material non compliance was found. The system meets standards, and the installation is considered satisfactory. |
Power conversion equipment
Checks safe, compliant installation of inverters and related equipment, including placement, wiring, isolation, labelling, configuration and performance.
Ground DC isolation
Assesses safety and compliance of ground-level DC isolators, ensuring correct ratings, wiring, weather protection, installation quality and recall compliance.
PV array
Covers installation and configuration of solar modules, including model verification, wiring, protection devices, connectors, fusing and layout compliance.
Performance
Covers system voltage limits, inverter compatibility and wiring losses to verify PV systems operate safely, efficiently and within Australian standards.
Roof DC isolation
Verifies rooftop DC isolators for safe installation, correct wiring, IP ratings, weather protection and signs of damage or deterioration.
Disconnection point
Checks presence, location and compliance of PV string disconnection points, including labelling, weather protection and safe wiring through roof spaces.
Array components
Assesses mounting systems, roof penetrations, wiring protection, earthing, cable routing and compliance with structural and wind-load requirements.
Wiring
Examines AC and DC wiring for correct installation, protection, UV resistance, segregation, labelling, enclosure integrity and termination quality.
Switchboard
Verifies switchboard labelling, circuit protection, isolation points, cable routing, inverter supply grouping and required PV site information.
Documentation
Checks all required system documentation, including equipment lists, ratings, diagrams, shutdown procedures, maintenance information and performance details.
Inverter power sharing devices (Solar for Apartments)
Covers installation and configuration of inverter power-sharing devices, verifying wiring, ratings, isolation, placement, testing and standards compliance.
