SunPower Maxeon Cell

The SunPower Maxeon Cell is made up of three main components.

Solid Copper Backing

Solid copper backing adds greater strength to the cell, avoiding cracking and fighting against corrosion.

No Gridlines

The top of the cell is designed with no gridlines to minimise reflected light, this allows the cell to capture light which would otherwise have been reflected. This also provdes greater aesthetics and gives the panel a sleek, minimal look.

Thick Connectors

The inclusion of thick connectors which adapt to the changing environment enable the panel to withstand sudden temperature changes, whereas generic panels will lose efficiency as the temperature increases, the maxeon cell’s built-in strain relief withholds its higher efficiency.

Dedication to sustainability

SunPower were the first manufacturer to become Cradle to Cradle Certified Silver, for their environmental approach to manufacturing within their global operations.

Not only do SunPower empower customers to reduce their global footprint, as a company they are also dedicated to reduce their own impact on the environment with ecological advances in the manufacturing process of their panels.
