There are various currents inside the cell, such as dark current, reverse current, leakage current, etc. Various currents have a greater or lesser impact on the power of solar panels. Distinguishing the characteristics of various currents can identify the cause of abnormal solar panel power and help solve the problem completely. dark current Dark current (DarkCurrent), also known as unilluminated ...
Reasons for low insulation resistance: When the solar panels or DC cables and joints are damaged or the insulation layer is aging, the problem of low insulation resistance is easy to occur. When the DC cable passes through the bridge, since the edge of the metal bridge may have barbs, the outer insulation of the cable may be damaged during the threading process, resulting in leakage to the ground....
With the popularization and application of industrial and commercial photovoltaics, more and more industrial enterprises are using their factory roofs to build photovoltaic power generation system. There is usually no objection to installing photovoltaics on the south slope, but how to deal with the installation of photovoltaics on the north slope of the color steel roof. Whether to continue to us...
