Problems solved by technology
[0002] Photovoltaic power generation, as a clean and renewable new energy power generation method, has developed rapidly in recent years, but currently installed photovoltaic power plants generally have problems of low power generation efficiency and high cost. One of the main reasons is that photovoltaic power plants are under long-term sunshine. , PV modules have not been cleaned in a timely and effective manner, resulting in a significant reduction in the efficiency of the PV power plant system. Studies have shown that 9% of the dust on the PV modules will cause 54% of energy loss

The invention provides a method for calculating a cleaning period of a photovoltaic power station. The method comprises the following steps: setting a comparison power station corresponding to the photovoltaic power station; cleaning a comparison power station; acquiring first power generation efficiency of the comparison power station; acquiring second power generation efficiency of the photovoltaic power station; and comparing the first power generation efficiency with the second power generation efficiency, and if the difference between the first power generation efficiency and the second power generation efficiency is not less than a set value, enabling the photovoltaic power station to enter a cleaning period. Therefore, whether the photovoltaic power station needs to be cleaned or not is judged after comparison, unnecessary cleaning loss is avoided, the cleaning cost of the photovoltaic power station is reduced, cleaning of the photovoltaic power station is more timely and effective, the situation that the power generation efficiency of the photovoltaic power station is reduced due to dust shielding is avoided, and the power generation efficiency of the photovoltaic power station is effectively improved.
Description
technical field [0001] The present application relates to the technical field of photovoltaic power plants, and in particular, to a method for calculating the cleaning cycle of photovoltaic power plants. Background technique [0002] Photovoltaic power generation, as a clean and renewable new energy power generation method, has developed rapidly in recent years, but currently installed photovoltaic power plants generally have problems of low power generation efficiency and high cost. One of the main reasons is that photovoltaic power plants are exposed to long-term sunlight , PV modules are not cleaned in a timely and effective manner, resulting in a great reduction in the efficiency of the PV power plant system. Studies have shown that 9% of the dust on the PV modules will cause 54% of the energy loss. SUMMARY OF THE INVENTION [0003] The present application aims to solve one of the technical problems in the related art at least to a certain extent. [0004] Therefore, ...
