LONGi and SunPower are both shortlisted on Perth roofs, but they come at the choice from different angles. LONGi is one of the largest monocrystalline panel makers in the world, with a current-generation high-efficiency residential range; SunPower is a long-established brand whose Performance (P7) panel — now made by Maxeon — is its high-value residential option. This is a fair, spec-led comparison for WA homes, not a verdict.
Specifications, pricing and eligibility change over time — always confirm the current details with your installer.
A widely-respected panel brand positioned on efficiency and manufacturing scale, often shortlisted alongside the other large-volume makers.
Origin
Chinese-made — a very large global manufacturer of monocrystalline wafers and panels, widely available in Perth.
Architecture
N-type modules (the Hi-MO range) built on LONGi's own monocrystalline wafer supply chain.
Strengths
Things to weigh
Australian support
Established 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 efficiency and manufacturing scale from a large, established panel maker.
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.
