Abstract

The present invention is applicable to the technical field of photovoltaic power generation, and provides a method for determining the dust accumulation cleaning period of photovoltaic power generation components. First, the first relationship between the dust accumulation density and light transmittance on the photovoltaic power generation components and the light transmittance of photovoltaic power generation components are deduced respectively and the second relational expression of power generation, and then derive the relational expression of photovoltaic power generation module power generation and cleaning period according to the first relational expression and the second relational expression. Therefore, the operator can determine the cleaning cycle through the final relational expression. The cleaning cycle specified by this method is more reasonable, and can achieve the effect of neither wasting resources nor affecting normal power generation.

Description

technical field [0001] The invention belongs to the technical field of photovoltaic power generation, and in particular relates to a method for determining a dust accumulation cleaning period of a photovoltaic power generation module. Background technique [0002] In recent years, in the face of increasingly prominent environmental problems, countries around the world have formulated and implemented long-term sustainable development strategies for new energy sources such as wind and light, and the proportion of new energy power generation to total power generation has continued to increase. With the continuous reduction of the cost of the photovoltaic industry and the implementation of subsidy policies, the photovoltaic industry has developed rapidly, and photovoltaic power generation projects have been put into operation on a large scale in areas with various light intensity. The fundamental problem in the development of the photovoltaic industry is the issue of cost and be...
