Solar Energy O&M Service
Why conduct O&M Management?
By reason of air pollution, salt damage, biogas, exhaust and drainage equipment, and little chance of rain in Taiwan environment, the dust, biogas, oil pollution, birds’ droppings, etc., easily adhere to the solar modules. If the power plant adopts traditional inverters, due to the string effect, the low current of a single module will affect the power generation of the other 20-21 modules in the same string, and even lead to hot spots because of the increase in resistance in modules. In order to retard and prevent the above situations, it is essential to have regular maintenance and management executed by a professional O&M team.
