SOLARBUILDERMAG.COM | 47 LG LG's "V5" series of modules is slated to enter the market in Q2 with some incremental product improvements, in addition to an enhanced warranty, which has one of the lowest degradation rates, and a 25-year product and performance guarantee. NeON2 "CELLO" cells, which have Cell connection with Electrically Low Loss and Optical Absorption Enhancement, create greater yield and less reflection through increased usable surface area on the front of the cell and greater reliability if the cells were to become micro-cracked. Warranty: 25-year linear, extended to 89.6 percent performance. Rated power 340 W Cell type n-type / monocrystalline Module efficiency 19.8% Short-circuit current 10.53 Open circuit voltage 41.1 Rated current 9.86 Rated voltage 34.5 Temperature coefficient (Pmax) -0.37% Temperature coefficient (Voc) -0.27% Temperature coefficient (lsc) 0.03% Quantity per pallet 25 Aesthetics 6 Value is often in the eye of the beholder, and as residential solar adoption widens and as the new build market explodes in California, aesthetics of rooftop panels will matter more and more. This is why all of the top residential module manufacturers now have an all-black version of their f lag- ship product, which are often priced a tad higher. Similarly, thin-f ilm PV could be on the upswing in the U.S. residential solar sec- tor. Swedish solar energy company Midsummer reports that it has received an order from Sunf lare for equipment for the production of thin f ilm solar cells worth over $7 million. Midsummer's DUO sys- tem is one of the most widely distributed manufacturing tools for f lexible CIGS solar cells in the world. Sunf lare, with global headquarters in La Verne, Calif., is a provider of f lexible mass-produced thin f ilm solar products that are especially suitable for weak roofs and new roofs for private homes. "The demand for our products in the U.S. has exceeded our expectations and we rapidly need to expand our production capacity with the help of our established partner Midsummer," says Philip Gao, CEO of Sunf lare.
