According to the product supplier's instruction manual, maintain the parts that need regular inspection. The main maintenance work of the system is to wipe the components. In areas with heavy rain, manual wiping is generally not required. In non-rainy season, cleaning is about once a month. In large areas, the number of cleanings can be increased. In areas with heavy snowfall, the heavy snow should be removed in time to avoid affecting the power generation and unevenness after the snow melts, and timely clean up blocked trees or debris.
