Free Solar Panel Quotes for Australian Homes — Compare Prices & Installers in 2026

Indicative 2026 pricing after the federal STC discount: about $4,000–$6,500 for 5kW, $5,000–$8,000 for 6.6kW (often $5,000–$7,500 in competitive metro markets), and $7,000–$12,000 for 10kW. The STC is a point-of-sale discount based on system size, postcode zone and market spot price — not a cash rebate paid later. Battery add-ons commonly add $10,000–$16,000 before the Cheaper Home Batteries Program (~$372/kWh usable capacity; ~$3,720 off a typical 10kWh battery). Exact quotes depend on roof, brand, DNSP export limits and labour. Compare sizes on our solar cost guide, then get firm CEC-installer quotes below.

The Clean Energy Council (CEC) is Australia's peak body for the clean energy industry. CEC-accredited installers have completed approved training, hold relevant electrical licences, and comply with the CEC's Code of Conduct. Critically, you must use a CEC-accredited installer to be eligible for the STC point-of-sale discount (the federal solar rebate). Using an unaccredited installer can cost you thousands in foregone rebates and may void product warranties. Every installer on MrSolar is CEC-accredited.

The federal Cheaper Home Batteries Program has been available since 1 July 2025. It provides a subsidy of approximately $372 per kWh of usable battery capacity for eligible home battery installations. A 10kWh battery (such as the BYD Battery-Box 10.24) receives roughly $3,720 off the installed price. The program stacks with state-based battery rebates in VIC, SA, QLD, NT, and ACT. Check the Clean Energy Regulator for current eligibility — including income testing and approved battery models.

The right system size depends on your daily electricity usage and when you use it. A typical Australian household uses 15–20kWh per day. A 6.6kW system (the most popular residential size) generates roughly 25–30kWh per day in most Australian capitals. If you have a pool, ducted AC, or an EV, a 10kW system is often more appropriate. Homes with batteries benefit from oversizing the solar array. The installers we connect you with will assess your bills, roof orientation, and shading before recommending a size.

Australia has the world's highest rooftop solar penetration — over 6.5 million small-scale systems installed nationally (CER data), and more than 1 in 3 homes now have solar. With electricity prices among the highest in the OECD (most households pay 25–40c/kWh), STC rebates that typically reduce upfront cost by about $917–$2,550 for a 5–10kW residential system (based on MrSolar's master table at $39.85/STC as of 5 Aug 2026), and feed-in tariffs for excess export, the payback period for a well-sized system is typically 4–7 years. For a home spending $2,500 per year on electricity, solar commonly reduces that bill by $1,000–$2,000 per year.

A feed-in tariff (FiT) is a credit your energy retailer pays for each kilowatt-hour of solar electricity you export to the grid. FiT rates vary significantly by state and retailer: from 2–8c/kWh in NSW to 7–11c/kWh in the ACT. Because self-consumption of solar (avoiding paying 28–36c/kWh import rates) is worth more than export, maximising self-consumption with a battery or smart appliance scheduling typically delivers better returns than relying on high feed-in tariffs. Our FiT comparison tool can help you compare retailers.
