SunPower Corp’s Photovoltaic module product line utilizes SunPower’s breakthrough all-back contact solar cells.

With conversion efficiencies approaching 17%, SunPower’s PV modules provide exceptional power density, along with an optional “all-black” design that enhances the appearance of roof-mounted PV arrays.

SunPower’s focus on product appearance starts with innovative all-back-contact solar cells. The entire front surface is uniformly dark and free of the metal gridlines; this gives the cells a velvety-black appearance. With all electrical contacts present on the back of the cell, there is no blockage of sun on the front. This smart engineering feat enables SunPower cells to achieve a conversion efficiency of over 20% – up to 50% more power than traditional products.

This smart technology extends through to the construction of the modules. Exceptional low-light performance and high sensitivity to light across the entire solar spectrum means that SunPower modules convert virtually every available photon into useable electricity, maximizing yearly energy production. The solar modules use only the highest quality 4 mm-thick high transmission strengthened glass for enhanced stiffness and impact resistance. Unique cell interconnect innovations from the aerospace industry allow SunPower to create modules with exceptional long-term reliability, and an advanced encapsulation system meets the most stringent safety requirements for high-voltage operation. With SunPower’s all black modules, there are no obvious visible features that interrupt the uniform smooth appearance.
