Indicative 2026 pricing: a typical 6.6kW system often quotes around $5,000–$8,000 after the STC discount (metro installs often $5,000–$7,500; premium/regional can run higher). See our solar cost guide.

Accredited designers and installers meet CEC training and conduct requirements for grid-connect PV work. STCs — still the main federal upfront discount, with spot context $39.85 as of 2026-08-05 — require eligible practitioners and products. Accreditation is not a personality award; it is the ticket to the legal incentive pathway most homeowners rely on. Compare at least three Clean Energy Council accredited proposals with identical inclusions, product models and workmanship warranty terms before you sign. Use this comparison to brief installers with a clear preference and a fallback — then price both options with the same CEC-accredited shortlist via MrSolar so hardware choices stay constant. Save PDFs of every plan, approval and datasheet — warranty claims years later depend on that trail.
Shaving labour cost while losing thousands in STCs is not a bargain. Non-compliant work can also complicate DNSP energisation and insurance claims after roof leaks or DC faults. Rectification by an accredited team later often exceeds the original “savings”. If a quote cannot show accreditation numbers, stop. Compare at least three Clean Energy Council accredited proposals with identical inclusions, product models and workmanship warranty terms before you sign.

Ask for CEC accreditation details and confirm them on official lists. Match the business entity on the quote. Check that panel and inverter models appear on CEC approved product lists. Request workmanship warranty terms in writing. These steps matter more than browsing anonymous star ratings — and fabricated AggregateRating claims should be ignored.

Storage adds electrical complexity and rebate paperwork. The Cheaper Home Batteries Program (~$372/kWh usable since 1 July 2025) and state battery schemes expect compliant installation pathways. Non-accredited experiments jeopardise discounts and safety. Hybrid systems are not a DIY weekend project. Keep decisions grounded in your interval data, roof constraints and written DNSP settings rather than national averages or salesperson screenshots.
