365QPDG10 BK is part of the Q.Peak Duo G10 Series one of the most recent made by Q CELLS. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 365QPDG10 BK 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. Q CELLS made solar cells in 365QPDG10 BK two times smaller than the standard size, thus reducing power loss and improving low-light behavior. The efficiency of this model reaches 20.3% well above the markets average. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Q CELLS provides an industry-leading 25-year performance warranty and a 25-year product warranty. 120 half-cut monocrystalline cells 365 W nameplate capacity 20.3% efficiency 1000 V DC maximum system voltage MC4 connectors 25 year of product and 25 year of performance warranty
