Solar panels for your Perth home.

The installed price depends on system size, equipment and site work. Ask for an itemised quote showing installation, the small-scale technology certificate (STC) discount, any other applicable incentives and any exclusions.

The right size depends on how much electricity you use, when you use it, available roof space and connection requirements. Future plans such as an EV or battery also matter. A site-specific design should explain why the proposed size suits your home.

Shade, roof orientation, available space and roof condition can affect the design and expected generation. An assessment should identify these constraints before the panel layout and equipment are finalised.

Often yes, but the connection method depends on your inverter, electrical setup and chosen battery. Discuss future storage when designing your solar system, and ask what “battery-ready” means for the equipment being quoted. In the South West network, adding a battery also needs Western Power’s approval before it is connected.

Hybrid inverter and battery packages we install include Sigenergy and iStore systems.

A standard grid-connected solar system generally shuts down during a grid outage. Backup requires suitable equipment and configuration. A battery alone does not guarantee whole-home backup; the quote should identify which circuits can operate and any limits.

Export limits cap how much electricity your system can send to the grid, which is separate from how much it can generate. In the South West network, the limit that applies depends on your connection type, your local network and whether you have an export arrangement with your electricity retailer. New and upgraded systems also need to meet Western Power’s current connection requirements.

Your proposed design should state the limit that applies to your home and how it interacts with your household usage and any battery.

Compare the exact panel and inverter models, proposed capacity, installation scope and any additional electrical work. Check incentives, exclusions, warranties and support arrangements so you are comparing equivalent offers.

Check that the panels and inverter are on the Clean Energy Council approved products list, ask for the installer’s Solar Accreditation Australia number, and ask which export limit applies.

Coverage depends on the equipment and installation agreement. Ask for panel product and performance warranties, inverter coverage and workmanship terms separately, including exclusions and any labour or call-out costs. Confirm who to contact for support and what monitoring is included.

These warranties are in addition to your rights under the Australian Consumer Law, which cannot be excluded.
