EVPV360PK is part of the EverVolt PERC Series one of the most recent made by Panasonic. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. EVPV360PK employs monocrystalline silicon the most efficient material for converting sunlight into electricity. Each of the model's 120 solar cells consists of a single crystal, unlike cheaper polycrystalline cells that are made of multiple crystals melted together. As a result, not only are monocrystalline panels more efficient, but they are also more resistant to degradation. Half-cut cell technology adds a few more percent to the overall performance, making this model a great example of efficiency. Panasonic made solar cells in EVPV360PK two times smaller than the standard size, thus reducing power loss and improving low-light behavior. At 19.7% efficiency, EVPV360PK offers surprising performance for its weight and size. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Panasonic provides an industry-leading 25-year performance warranty and a 25-year product warranty. 360 W power output 120 half-cut monocrystalline cells 19.7% efficiency 1000 V DC maximum system voltage MC4 connectors 25-year product and 25-year performance warranties
