330W Poly Crystalline Solar Panels

Solar panel is also called photovoltaic module or solar module.which is formed by connecting numerous solar cells. Solar cells connected each other in serial-parallel are packed in EVA(ethylene vinyl acetate) and due to fragility of cell, tempered glass is used on the surface of solar panel to enhance durability. In photovoltaic power generation system, in order to get necessary and sufficient power, on the consideration of roof form, roof direction, well-receiving of sunshine and width etc to select and use a suitable solar panel.
