Show series description

Maxeon 6 panels redefine performance standards through the use of patented IBC cell technology, in which all electrical connections have been moved to the back of the module. This solution completely eliminates shading of the active surface by front busbars, which translates into maximum absorption of sunlight even on cloudy days. The unique design based on a solid copper foundation makes this series almost completely resistant to corrosion and stress cracks, which often shorten the lifespan of standard components. Investing in these modules effectively solves the problem of limited roof space, as their record-breaking efficiency allows them to generate significantly more energy per square meter than competing solutions. This is a product dedicated to the most demanding investors who care about the longest warranty on the market and impeccable installation aesthetics. Maxeon 6 stands out with the lowest degradation rate, which guarantees yield stability for over four decades of use. Thanks to the use of innovative shingled technology, these panels handle partial shading and extreme temperature fluctuations much better, representing currently the most reliable choice for modern photovoltaic systems focusing on uncompromising quality of workmanship.

Panels from the same series differ mainly in power output while having identical dimensions. Learn why →
