The new era of back-contact, bringing together the best of SunPower’s pioneering patented technologies, leveraged through TCL’s global industrial strength and manufacturing capabilities.

Back Contact (BC) solar cells are a high-efficiency solar cell technology where both the positive and negative electrodes are placed on the backside of the cell. This design effectively reduces shading area and enhances the absorption and utilization efficiency of sunlight.
The founder of the BC technology is Dick Swanson, also founder of SunPower.
Designed for premium residential installations, SunPower Max delivers 490-505 W with efficiency up to 24.7%. Its high-density full-screen back-contact technology creates a clean, busbar-free front while supporting high energy density, lower operating temperature and reduced hotspot risk.

Power, Product & Service coverage for 30 years.
SunPower panels are manufactured for long-term durability, covering defects related to workmanship and materials for a full 30 years, versus some manufacturers that can go as low as 12 years on their warranty.
SunPower panels also account for the repair, replacement or refund of any defective panel for 30 years, with removal, shipping and installation included in Australia and New Zealand.
All our warranties abide by Australian Consumer Law and New Zealand Consumer Guatantees Act.


Unlock greater power with back contact shingled technology
This patented cell architecture means that the cells overlap. It eliminates inactive "dead zones" between cells, capturing more light and boosting overall panel output. This translates directly to increased energy production. Unlike standard half cut panels, where shading across a single cell can significantly impact output, shingled cells minimise power loss under shaded conditions
Cell-level bypass diodes create alternative paths for electric current, reducing the risk of uncontrolled heating and the formation of hotspots. Reduced internal cell temperatures prolongs the lifespan of panels while optimising energy generation (even in low-light conditions).
The SunPower Max panel has an all black sleek design, no trade-off between aesthetics and efficiency. The busbar free design eliminates front metal lines, presenting a more visually appealing rooftop installation.
SunPower Max modules have a robust glass-glass construction. Their double layered glass construction enhances durability, safeguarding against environmental factors, installation stresses and ensures a longer product lifespan.
SunPower Max with its premium encapsulant and durableglass-glass construction, is certified up to 40mm hail impact.
SunPower Max panels can be installed as close as 50 meters from the sea. It is certified to the highest severity for salt mist (test method 8), ensuring corrosion resistance and reliable performance.
SunPower Max has gone though extensive ammonia resistance testing, guaranteeing performance in agricultural and high-ammonia environments.
