As more Australians embrace renewable energy, selecting the right solar panels has become essential for maximizing performance and ensuring a solid return on investment. However, with such a wide range of brands and options available, the choice can often feel overwhelming. That’s why, leveraging over a decade of hands-on experience in the solar industry—and working closely with our team of 12 certified installers at Aussie Solar Tech—we’ve compiled straightforward, trustworthy insights grounded in real-world performance, genuine customer feedback, and the latest market trends.
At the same time, we estimate a range of popular solar Panel brands and score them out of 50. AIKO came out on top with an impressive average of 45 marks, followed by SunPower with 33 and REC with 29, Jinko scored 20, Trina 14, Longi 12, and Qcell, Canadian received 10 marks, while Risen and TW each earned 5. These scores reflect not just technical specs, but also our hands-on experience and what we’ve seen work greatest for Australian homes.
1. Panel Efficiency
Efficiency indicates how well a panel converts sunlight into electricity. We prioritized panels with higher conversion rates (typically over 21%), as these are better suited for rooftops with limited space or where maximum output is required. For 2025, several brands have reached or exceeded 23%, making them highly competitive in the Australian market.
2. Product & Performance Warranty
We examined both the length and quality of warranties. While most manufacturers offer a 25-year product warranty, some premium brands like SunPower provide up to 40 years of coverage. We also assessed performance warranties, which indicate how much power the panel is expected to produce after 25 years. Panels with 90% or higher output retention were rated more favorably.
3. Long-Term Performance and Degradation Rate
Over time, all solar panels degrade, but the rate varies by brand and technology. We analyzed year-25 performance data to understand how much energy a panel retains after decades of use. Lower degradation rates suggest better manufacturing standards and long-term reliability, especially important in Australia’s sometimes extreme weather conditions.
4. Build Quality & Technology
We considered the cell structure (e.g. N-type vs P-type), panel materials, and innovations such as heterojunction technology (HJT), tunnel oxide passivated contact (TOPCon), or IBC cells. Brands offering advanced technologies that increase output or reduce temperature-related losses scored higher.
5. Real-World Performance in Australian Conditions
Lab data doesn’t always reflect real-world performance. We incorporated installer feedback and user reports from across Australia—covering metro cities, rural towns, and regional zones. Some panels perform exceptionally in cooler climates but struggle in high-heat environments. Our rankings reflect adaptability across varying weather patterns.
6. Brand Reputation and Customer Support
A strong manufacturer track record, responsive after-sales service, and a solid presence in the Australian market were also taken into account. We looked at how long the brand has operated, their installer network, and how quickly they respond to warranty claims.
7. Price and Value for Money
Not everyone can afford top-tier panels. That’s why we included a mix of premium, mid-range, and budget-friendly options—evaluated not just on price, but on what you get for your money. High-performing, lower-cost panels that deliver solid efficiency and decent warranties were rated as excellent value.
8. Availability and Installer Access
Some high-end panels aren’t widely available or may only be installed by certain certified installers. We made sure to include panels that are accessible to Australian homeowners and small businesses through established distributor networks.
Why Our Approach Matters
We understand that no two homes or businesses are the same. What’s best for a family in Sydney might not suit a commercial installation in Canberra. That’s why our Residential is designed to provide clarity—not just on which panel is best but which one is best for you. By combining data, expert input, and real-life usage insights, we’ve created a resource that puts the power of informed decision-making in your hands.
