Introduction
Solar rail mounting systems are the core support of all PV power generation projects, and the open ends of solar square tubes and U steel rails are vulnerable parts exposed to the outdoor environment. High-quality solar rail end caps are essential accessories for solar bracket protection, which can effectively block outdoor dust, rainwater, dew, insects and other impurities from entering the hollow rail interior. This practical protection avoids internal rust, corrosion and pipeline blockage, greatly extending the overall service life of solar mounting rails for rooftop, ground-mount and solar carport systems.
