Choosing a solar energy company in Perth

What to look for

A written quote that names the exact brands, model numbers, system size in kW and inverter size.
Separate product warranties (panels often 10 to 25 years, inverters 5 to 10) plus the installer's own workmanship warranty.
Help with Western Power connection approval, since export limits and inverter rules vary by network area.
A local office and a record of still being around to service what they sell.

Common questions about solar energy company
- How much does a solar system cost in Perth?
- As a rough guide, a 6.6 kW system with a 5 kW inverter commonly costs between $4,000 and $7,000 after the federal small-scale incentive, depending on brands and roof complexity. Adding a home battery usually adds several thousand dollars or more. Get at least three itemised quotes.
- How long does installation take?
- Most home rooftop installs take one day, sometimes two for larger or complex roofs. Allow a few weeks before that for design, paperwork and Western Power approval, and a little time afterwards for the connection to be confirmed.
- How do I judge the quality of a solar quote?
- Check that the installer is CEC accredited, the products are on the CEC approved list, and the quote names brands, models and warranty terms. Be wary of pressure tactics, vague 'package' wording or prices far below the others.
- How often does a solar system need servicing?
- Panels need little upkeep. A visual check and clean every year or two is reasonable in dusty areas, and inverters are the part most likely to need attention, typically after 10 to 15 years.
