Description
SunPower 390W Mono PERC Shingled Solar Panel (SPR-P19-390-COM | P-Series) is a high-performance photovoltaic module designed for residential and light-commercial solar installations where durability, shade tolerance, and long-term reliability are critical. As part of SunPower’s Performance Series, this panel combines monocrystalline PERC technology with a shingled cell architecture, delivering consistent energy output in real-world rooftop conditions.
The shingled cell design uses overlapping mono-PERC cell strips bonded with conductive adhesives rather than traditional busbars. This reduces internal resistance, improves current flow, and enhances performance under partial shading. The panel is engineered for standard string inverter systems and supports 1000 VDC system designs, making it suitable for a wide range of residential and small commercial applications.
Built for outdoor deployment, the module features reinforced construction and materials selected to withstand wind, snow, and temperature extremes. Its standardized form factor integrates easily with common racking systems and pairs well with modern grid-tied and hybrid inverters.
