SunPower Residential P3-320-BLK-Res-MC4 Series - 6.5KW

Performance 3, Residential Series, 320W - x21 SunPower Performance Panels wrap front contact cells with 30+ years of SunPower materials and manufacturing expertise. The weakest points of Conventional Panel design are eliminated to deliver superior power, reliability, value and savings. High Power: Enhanced active area and monocrystalline cells increase power and savings while designing out fragile ribbons and solder bonds on the cells. High Performance Up to 26% more energy in the same space over 25 years.2 Outperforms Conventional Panels in partial shade thanks to unique parallel circuitry. Proprietary bussing design limits power loss, maximizing production during morning and evening shading or soiling. High Reliability SunPower Performance Panels are the most deployed shingled solar panel in the world. Innovative cell shingling mitigates the leading reliability challenges associated with conventional front contact panels by designing out fragile ribbons and solder bonds on the cells. SunPower stands behind its panels with its industry-leading Complete Confidence Warranty. SunPower’s Performance Panels are warranted to produce more than 97.5% power in the first year, then declining by 0.5% per year, ending at 85.5% power after 25 years. SunPower Performance Panels with their black frame and black back sheets blend harmoniously into your roof and add elegance to your home.
