IBC Maxeon Cells

SunPower’s interdigitated back contact (IBC) cells place all electrical contacts on the rear, maximising the light-absorbing front surface for some of the highest efficiencies on the market.

Maxeon 6: Up to 440W

The Maxeon 6 series achieves up to 440W per panel with efficiencies above 22.7%, placing it among the highest-output residential panels available in Australia.

Up to 40-Year Warranty

Select Maxeon panels come with up to a 40-year combined product and performance warranty, the longest in the residential solar panel market.

40 Years of Experience

Founded in 1985, SunPower has nearly four decades of solar manufacturing experience. The company has one of the longest continuous track records in the industry.

National Warehouse Network

Warehouses in Melbourne, Sydney, Brisbane, Adelaide, and Perth ensure fast stock availability and warranty part supply across all major Australian metros.

TCL Backing Since 2025

TCL’s acquisition brings additional manufacturing scale and financial backing while SunPower retains its brand identity, product engineering, and Australian support team.

SunPower offers the longest warranty in the residential panel market (up to 40 years) and the most extensive Australian support network among premium brands. REC competes closely on cell technology (HJT vs IBC) with slightly lower pricing. LONGi offers a mid-premium option with strong global manufacturing scale. All three use advanced N-type cell technology with better temperature performance and lower degradation than conventional PERC panels.

Are SunPower panels still good after the TCL takeover?

TCL completed its acquisition of SunPower in March 2025. Early indications are that the existing product lines (Maxeon, Performance series), warranty programs, and Australian support infrastructure remain in place. TCL is a large electronics manufacturer with the resources to maintain and invest in SunPower’s operations. The key for consumers is whether long-term warranty commitments (up to 40 years) will be honoured, which depends on the ongoing financial health of the combined entity.

Is SunPower the best solar panel brand?

SunPower is consistently rated among the top residential solar panel brands globally. The Maxeon IBC cells are among the most efficient residential cells available, and the 40-year warranty is the longest on the market. In Australia, SunPower has a 15+ year track record with strong local support. The main trade-off is price: SunPower Maxeon panels are among the most expensive residential panels available. For homeowners prioritising long-term performance and warranty coverage, SunPower is a strong choice.

How much do SunPower panels cost in Australia?

SunPower Maxeon panels typically cost 20 to 40% more than mid-tier alternatives like Jinko, Trina, or Canadian Solar. A 6.6kW system using SunPower Maxeon 6 panels might cost $8,000 to $12,000 installed (before rebates), compared to $5,000 to $7,000 for a mid-tier system. The Performance series is more affordable but uses conventional cell technology. Ask for an itemised written quote so you can see what the panels add to the price.

What is the difference between SunPower Maxeon and Performance series?

The Maxeon series uses SunPower’s proprietary IBC cell technology for maximum efficiency and up to 40-year warranties. The Performance series uses conventional cell technology (similar to other mainstream brands) at a lower price point with standard 25-year warranties. Maxeon panels also feature SunPower’s solid copper foundation that makes the cells more durable and resistant to corrosion.

Who owns SunPower now?

SunPower is now wholly owned by TCL, a Chinese electronics conglomerate known for TVs, appliances, and displays. TCL completed its full acquisition of SunPower in March 2025. Before the acquisition, SunPower was a publicly traded US company (previously spun off from Maxeon Solar Technologies). The brand continues to operate under the SunPower name in Australia.
