Aiko and SunPower sit at opposite corners of the panel market. Aiko's all-back-contact (ABC) panels are among the highest-efficiency residential modules available, from a newer but fast-growing maker; SunPower's Performance (P7) — now made by Maxeon — is the high-value panel from a long-established brand. This is a fair, spec-led comparison for WA homes, particularly if roof space is tight.
Specifications, pricing and eligibility change over time — always confirm the current details with your installer.
A rising high-efficiency challenger known for all-back-contact (ABC) panels at the upper end of residential efficiency.
Origin
Chinese-made — a newer but rapidly-growing panel manufacturer that has gained strong traction in the Perth market.
Architecture
All-back-contact (ABC) N-type modules — contacts move to the rear of the cell for high efficiency and a clean all-black appearance.
Strengths
Things to weigh
Australian support
Growing Australian distribution presence.
WA rebate
Panels qualify for federal STCs (Perth is STC Zone 3); value depends on system size and the STC spot price. No separate panel rebate.
Tends to suit
Buyers who prioritise maximum efficiency or have constrained roof space, and are comfortable paying a premium for a newer high-efficiency brand.
A well-recognised brand; the Performance (P7) series is its high-value residential panel in Australia — upper-mid on efficiency, with a notably long warranty.
Origin
A long-established panel name, now made and warranted by Maxeon Solar Technologies (majority-owned by China's TCL). The Australian SunPower operation is separate from the US SunPower company that restructured in 2024.
Architecture
Performance P7: N-type TOPCon cells in a shingled, one-third-cut, glass-glass design — an all-black panel with no visible busbars.
Strengths
Things to weigh
Australian support
Warranted in Australia through Maxeon's local SunPower operation.
WA rebate
Panels qualify for federal STCs (Perth is STC Zone 3); value depends on system size and the STC spot price. No separate panel rebate.
Tends to suit
Buyers who want a long warranty and an established panel name in a clean all-black design, and don't need the absolute highest efficiency.
