Description
The SunPower SPR-P19-390-COM is a commercial-grade shingled monocrystalline PERC solar panel engineered to deliver up to 32% more energy over 25 years compared to conventional panels in the same footprint.
Key Features
- Shingled Cell Design with Parallel Circuitry: Eliminates fragile ribbons and solder bonds while enabling superior shade and soiling tolerance through proprietary parallel cell connections.
- 18.9% Module Efficiency: Enhanced active cell area and unique electrical bussing deliver 15% more power output with reduced panel operating temperatures versus conventional designs.
- PID-Free at 1500V: Tested and confirmed free of Potential-Induced Degradation at maximum system voltage, ensuring long-term performance stability in high-voltage string configurations.
- DNV/GL Top Performer — All Reliability Tests: Named a top performer across all DNV/GL PV Module Reliability Scorecard evaluations, with aerospace-grade conductive adhesive and redundant cell connections.
- 25-Year Complete Confidence Warranty: Industry-leading combined product and performance warranty covers the full 25-year service life with a +5/-0% power tolerance at STC.
Rated for hail impact resistance up to 1-inch diameter at 52 mph, and engineered to withstand wind loads of 2,400 Pa and snow loads of 5,400 Pa, the SPR-P19-390-COM is built for demanding commercial rooftop environments. The Class 2 silver anodized aluminum frame and IP-67 rated junction box ensure long-term structural and weathering durability.
Compatible with ungrounded, positive, or negative grounded DC systems up to 1500V, the SPR-P19-390-COM is UL, CEC, and FSEC listed and certified to ISO 9001, ISO 14001, IEC 62716 ammonia resistance, and IEC 61701 maximum severity salt spray.
