AI Technical Summary
Photovoltaic panels are prone to accumulate particles such as dust during outdoor operation, resulting in a decrease in cleanliness, affecting the photoelectric conversion efficiency, and increasing heat transfer thermal resistance, which may lead to excessive temperature and burnt dark spots. The prior art is difficult to detect the cleanliness of photovoltaic panels in a timely and accurate manner, resulting in frequent cleaning work increasing operation and maintenance costs and may damage photovoltaic panels.
A photovoltaic panel cleanliness detection system is provided, including a first and second photovoltaic panel connected in series or in parallel, a controller, a cleaning device, a thermometer, a photometer and a power detection module. By detecting the temperature difference and power difference between the two photovoltaic panels, the difference in cleanliness and determining whether to clean one or two photovoltaic panels based on the difference size.
It improves the accuracy of the cleanliness detection of photovoltaic panels, reduces unnecessary frequent cleaning work, reduces damage to the surface of photovoltaic panels, and ensures the stability of photovoltaic power generation efficiency.
