Solar panels and solar systems in Australia: prices and rules

Updated 4 November 2026

A single solar panel in Australia costs about A$77 to A$349, and a complete 6.65 kW home system starts from about A$5,200. Prices are approximate, from sellers' websites in November 2026. For an offer that fits your roof, caravan or shed, describe the system on BlaBlaPrice, and registered sellers can reply with their own offers.

Standards and accredited installers

A solar system has to meet the Australian standard for solar installations, AS/NZS 5033, which was revised to support efficient installation and safety. If you design or install a photovoltaic system, the Australian government lists the standards you must follow. For a home system, ask for an accredited installer, because accredited installers are trained and certified to meet the relevant standards.

Warranties and your rights

Panel makers offer long warranties, and some list 25 years on their panels. Consumer guidance on solar systems sets out your rights on installation, ongoing performance and warranties, and says a seller should not pressure you into buying. Get the warranty terms in writing before you sign.

Season and output

Summer runs December–February, with the longest days, so a system installed in November starts producing before the peak months. In winter, June–August, output falls, so size the system for the months you actually need power.

Panel size, voltage and what comes in the kit

Panels are listed in watts (W), as 12 V or 24 V units for caravans and boats, and home systems in kilowatts (kW). Kits often include mounting brackets and a cable; one 200 W kit includes a 6-metre extension lead. Prices are in Australian dollars, and frame sizes are given in millimetres.

What to write in your request

Say what the panels are for (home roof, caravan, shed or off-grid), the total power in W or kW, and whether you need batteries. Give the number of panels, the installation address and whether you want full installation or a kit for a DIY job. Add a budget in A$.

BlaBlaPrice is free for buyers. Describe the system in your own words in the chat, and add a photo of the roof or site if you have one. BlaBlaPrice's AI asks for missing details, looks through sellers' websites and price lists in Australia, and shows the prices and businesses it found. Sellers registered on BlaBlaPrice reply in the chat with their own offer. Your contacts stay hidden until you choose to share them. If you also need storage, see backup power batteries or power inverters, or create a request on the home page.
