Introduction of Shingled Cells Technology
There are a variety of key technical differences between SunPower Performance solar panels and Conventional Panels, including the design and layout of the solar cells, the conductive material used, and the electric architecture—which combine to enhance the reliability, performance and aesthetics of Performance panels.
To go into a bit more technical detail, first, we laser cut each SunPower Performance cell into six strips and layer them in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows us to fit more active cell area into each panel, boosting power and efficiency. Second, Performance cells are connected with a conductive adhesive borrowed from the aerospace industry to offer multiple and redundant paths for energy flow. This allows us to remove the front contact conductive ribbons and solder bonds found in conventional cells that can block active cell area and deteriorate over time, leading to cell failures and power deficits. Finally, SunPower Performance panels feature a unique parallel circuit architecture that significantly limits power loss in shade and soiling. The result is a superior shingled panel constructed with commodity cells, outperforming conventional panels in efficiency, performance and reliability
