Question 2

How much does a solar system cost in Australia in 2026?

Accepted Answer

Indicative 2026 pricing after STC: 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. Battery add-ons commonly add $10,000–$16,000 before the Cheaper Home Batteries Program (~$372/kWh usable). See mrsolar.com.au/solar-panels/cost/ then compare CEC-installer quotes.

Question 3

What is CEC accreditation?

Accepted Answer

The Clean Energy Council (CEC) is Australia's peak body for the clean energy sector. Only CEC-accredited installers are eligible to install solar systems under government rebate schemes (STC point-of-sale discounts). All installers on MrSolar hold current CEC accreditation.

Question 4

What solar rebates are available in Australia?

Accepted Answer

Most Australian homes qualify for the federal Small-scale Technology Certificate (STC) point-of-sale discount, but the dollar value depends on system size, postcode zone and STC market price. Using MrSolar's master STC table (spot price $39.85 as of 5 August 2026), the typical 5–10kW residential range is about $917–$2,550, while a typical 6.6kW system is about $1,235–$1,674. State-specific rebates include VIC's Solar Homes Program (up to $1,400), SA's Home Battery Scheme, QLD's Battery Booster ($3,000–$4,000), and the federal Cheaper Home Batteries Program which has been available since 1 July 2025.

Question 5

What size solar system do I need?

Accepted Answer

A typical Australian household uses 15–20kWh per day. A 6.6kW system generates roughly 25–30kWh per day in most capitals. Homes with a pool, ducted AC, or EV often need ~10kW. Installers on MrSolar size from your bills, roof and shading.

Question 6

Is solar worth it in Australia?

Accepted Answer

Australia has the highest rooftop solar penetration in the world — over 1 in 3 homes now have solar panels. With electricity prices among the highest in the OECD and generous STC rebates, most Australian homeowners see a payback period of 4–7 years and annual savings of $1,000–$2,500.
