Sunpower 320 P Series

SunPower Performance Series – 320 Watts

SunPower Performance panels offer 19.6% panel efficiency and up to 32% more energy over the first 25 years of operation when compared to Conventional Panels. Performance panels also benefit from a unique parallel circuit design that delivers more energy in row-to-row shading, enabling greater ground or roof coverage.

SunPower Performance panels differ from Conventional Panels in a variety of ways. First, all cells are laser cut into six strips and layered in a shingled configuration to create a ‘hypercell’. This shingled hypercell allows more active cell area to be fit 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 electricity flow. This removes the front contact 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.
