An innovative shingled design eliminates many of the reliability challenges of traditional front contact panels. Fragile ribbons and solder bonds are removed to expand the active cell area, flexible and redundant connections keep energy flowing, and lower peak cell temperatures enable longer panel life.
In the 2018 DNV GL PV Module Reliability Scorecard, SunPower Performance Series panels were named as a top performer in all five reliability tests conducted: thermal cycling, damp heat, humidity-freeze, dynamic mechanical load and potential induced degradation.
P-Series combines conventional cell technology with 30+ years of SunPower materials and manufacturing expertise to deliver more energy, reliability and savings. P-Series offers added protection in the form of our Complete Confidence Panel Warranty, delivering 25-year Power, Product and Service backing.
Compared to Conventional Panels, P-Series panels offer 7% higher panel efficiency* and up to 19% more energy over the first 25 years of operation.* P-Series panels also benefit from a unique parallel circuit design that delivers more energy in row-to-row shading, enabling greater ground or roof coverage
