Improved performance fo PV solar cells

BP Solar’s Poly 3 Series of PV solar cells over 75 W are now supplied with white Tedlar, thus improving their performance as the modules run cooler, which means more energy over the life of a system. This change is combined with a new power tolerance of ±3%; BP claims to be the first leading manufacturer to offer such a tight tolerance on Polycrystalline products. The Poly 3 Series carries a warranty covering power output for 25 years and freedom from defects for five years.
