Solar photovoltaic module KDM 290W 5BB poly

Kingdom Solar Energy Technic Co. - one of the most promising companies that manufacture PV modules and solar panels. Production capacity of 500 MW / year.

Solar Grade A elements are the elements of the highest quality. They have no chips, cracks or scratches which lead to a decrease in the efficiency of energy conversion of sunlight into electricity. They have a perfect appearance, uniformity of crystals, the color,. N. The filling factor of more such elements CVC 0.7. Solar cells are under solar radiation. Sunlight contains ultraviolet radiation which destroys the materials from which the solar module is made, including solar cells. Small defects in the materials become more pronounced over time c, so power generation by the solar modules is reduced. Since the elements Grade A have the smallest defects at the start, their degradation is the slowest. Kingdom Solar Energy Technic Co. make solar modules under its own brand only element of Grade A.
