During the power generation of the solar device 900, dust or other dirty matter may gradually fall off the light receiving surface 31 adhered to the non-self-cleaning photovoltaic device 3 and the light receiving surface 41 of the self-cleaning photovoltaic device 4, but Since the light receiving surface 41 of the self-cleaning photovoltaic device 4 is composed of a nano antifouling coating 42 having a self-cleaning function, dust or dirt is less likely to adhere to and be fixed to the light receiving surface 41, and is easily dewed. Or the rainwater is taken away, so the light receiving surface 41 is not easily shielded, and good light transmittance and power generation efficiency can be maintained. On the contrary, the light-receiving surface 31 of the non-self-cleaning photovoltaic device 3 does not have a self-cleaning function, so it is easily shielded by dust and dirt to reduce its light transmittance, so that the power generation efficiency is relatively gradually increased. decline.

Therefore, during the power generation process, the monitoring device 6 can simultaneously monitor and compare the difference between the self-cleaning photovoltaic device 4 and the power generated by one of the non-self-cleaning photovoltaic devices 3, and the comparison result meets the preset specificity.
