Frequently Asked Questions
This estimate provides a realistic market price range based on your system size, panel quality, inverter type, and roof complexity. It is designed to give you a useful guide, not a final on-site quote. Actual prices may vary depending on your specific roof conditions, shading, and the installer you choose.
Prices vary due to panel brand and tier, inverter type (string vs micro), battery inclusion, roof type and access, electrical upgrades needed, and installer margins. Two quotes for the same home can differ by thousands based on these variables.
Australian homeowners can claim Small-scale Technology Certificates (STCs) which reduce upfront costs by $2,000–$4,000 depending on system size and location. Some states offer additional rebates. Your installer will apply these automatically.
Every solar installer in the Direct network holds current Clean Energy Council (CEC) accreditation. We verify credentials, insurance, and workmanship warranty before any installer joins our network.
A standard residential solar installation takes 1–2 days on site. The full process from quote to power-on typically takes 2–6 weeks, including paperwork and grid connection approval.
Solar panels typically come with 25-year performance warranties. Inverters carry 5–12 year warranties depending on brand. Your installer also provides a 5-year workmanship warranty as required by CEC guidelines.
