Annual Solar Panel Cleaning & Inspection – 200kW Plant, Shizuoka

We carried out annual scheduled cleaning and inspection of a 200kW industrial solar power plant in Shizuoka Prefecture.

Bird droppings, dust, and pollen were removed from panel surfaces using a specialized soft-wash method. Insulation resistance measurements and infrared camera hot-spot inspections were also conducted, enabling early detection of anomalies. As a result, power generation efficiency improved by approximately 15%.
