A Answer: Common faults or problems of RV solar panels mainly include:
Defective cells: Cells may have color difference, color spots, water marks, fingerprints, positive electrode damage, scratches, broken edges, missing corners and other defects when leaving the factory, which will affect the efficiency of solar power generation.
Cell cracks: When the cell is subjected to greater mechanical or thermal stress, invisible cracks that are not easily detected by the naked eye may occur, causing the battery to short circuit and affect power output.
Hot spot effect: Due to the cracks in the raw materials of the cell or improper operations such as false welding and bubbles during the production process, the high temperature environment temperature of the solar panel is too high, causing the solder joints to melt, partially burn, and even cause fire.
Installation and maintenance issues: RV solar panels need to be wiped regularly to keep the surface clean to ensure power generation efficiency. At the same time, the installed power must be large enough to meet the power demand of the RV.
