Why Go Solar & Battery in 2026

Solar remains one of the best investments for Australian homeowners. While rebates phase down over time, the savings are real and lasting.

Lower Your Electricity Bills

The average Australian household saves $1,500+ per year with a 6.6 kW solar system, cutting electricity costs by up to 80%.

Take Advantage of Rebates

Federal STCs provide $1,600 to $2,200 off a 6.6 kW system. The Cheaper Home Batteries program adds around $2,520 off a 10 kWh battery under the tiered rates that took effect on 1 May 2026. Both phase down over time but remain significant.

Increase Your Home Value

Solar-equipped homes sell for 3% to 4% more on average. Buyers want lower running costs and energy independence, making solar a smart investment.

Over 270 solar companies have collapsed in Australia. 1 in 6 solar homes now have no workmanship warranty. We only partner with installers who have the track record to back their promises.

Frequently Asked Questions

SolarAuthority is an independent platform that helps Australian homeowners make informed solar and home energy decisions. You can compare solar quotes, CEC-approved products, government rebates, electricity plans, finance options, and connect with trusted SAA-accredited installers and NETCC-approved retailers—all in one place. It’s Absolutely FREE to join.

At SolarAuthority, we believe better solar decisions start with better information. We connect you with trusted SAA-accredited installers in your local area who can visit your property, assess your home's specific requirements, understand your current and future energy needs, and design a customised solar solution that helps you maximise performance, savings, and long-term value.

Your home is unique, and your solar solution should be too. While online tools and satellite images can provide an initial overview, they cannot fully understand important factors such as roof condition, shading throughout the day, electrical requirements, household energy habits, and your future energy goals.

CEC-approved solar panels, inverters, and batteries meet Australia's safety and performance requirements. Choosing approved products helps ensure your system is reliable, eligible for government incentives where applicable, and installed to industry standards.

Not All Solar Retailers Are the Same, some of them do not have NETCC approval.

Choosing a solar system is a long-term investment, and the retailer you trust to guide your decision plays a critical role in the outcome. While many solar retailers follow recognised industry standards, not every retailer is NETCC-approved. Retailers without NETCC approval have not been independently assessed against the New Energy Tech Consumer Code, which sets expectations around transparent sales practices, accurate information, contracts, warranties, and customer support.

Many homeowners focus only on panel brands, battery capacity, and price—but the quality of advice, system design recommendations, and after-sales support can have a significant impact on your overall solar experience. Choosing the wrong retailer may lead to unsuitable system recommendations, unclear expectations, or challenges when you need ongoing support.

At SolarAuthority, we help homeowners make more confident decisions by connecting them with trusted NETCC-approved retailers who commit to higher standards of transparency, professionalism, and customer protection. Before investing in solar, take the time to understand who is recommending your system and whether they meet recognised industry standards.

SAA-accredited installers have demonstrated the required technical competencies to install solar systems safely and correctly. NETCC-approved retailers have committed to consumer protection standards, providing greater transparency and confidence throughout your solar journey.

Australian homeowners may be eligible for federal and state government incentives, including Small-scale Technology Certificates (STCs), battery rebates, interest-free loans, and other state-based energy programs. Eligibility depends on your location, property, and the products you choose.

A solar battery stores excess electricity generated during the day so you can use it at night or during peak electricity pricing periods. Batteries can increase your energy independence, reduce electricity bills, provide backup power (for compatible systems), and enable participation in Virtual Power Plant (VPP) programs.

A Virtual Power Plant connects your compatible home battery to a network of other batteries. During periods of high electricity demand, your battery may export energy to support the grid. In return, many VPP providers offer bill credits, incentives, or ongoing financial benefits, depending on the program.

Yes. The right electricity plan can significantly improve your solar savings through competitive feed-in tariffs, lower usage rates, battery-friendly tariffs, and EV charging options. Comparing plans regularly helps ensure you're getting the best value from your solar system.

Yes. Many Australian finance providers offer solar loans, green finance, and flexible payment plans for solar systems, batteries, and EV chargers. Comparing finance options can help you find repayments and terms that suit your budget.

SolarAuthority brings everything together in one place—from independent guides and government rebates to product comparisons, accredited professionals, finance options, electricity plans, and transparent quotes. Whether you're just researching or ready to install, we help you make confident, informed decisions at every stage of your home energy journey.
