Why is the power generation of photovoltaic power plants not as high as expected during the continuo
发布时间:2024-5-31   文章来源:   

A while ago, there were consecutive hot days in various regions. According to our inherent consciousness, the power generation of photovoltaic power plants on hot days should be higher than before. However, many homeowners should have noticed that under continuous hot weather, the power generation of photovoltaic power plants is not as ideal. Why?

Firstly, high temperature weather can cause an increase in the temperature of photovoltaic cells, thereby reducing their battery conversion efficiency. The working principle of photovoltaic cells is to convert light energy into electrical energy, and the conversion efficiency of photovoltaic cells is closely related to their temperature. When the temperature rises, the conversion efficiency of photovoltaic cells will decrease, thereby affecting the effectiveness of photovoltaic power generation.

Secondly, high temperature weather can also accelerate the aging of photovoltaic cells. The lifespan of photovoltaic cells is closely related to their working environment, and high temperature weather can accelerate the aging of photovoltaic cells, thereby shortening their service life. This not only affects the effectiveness of photovoltaic power generation, but also increases the maintenance cost of photovoltaic power generation.

Thirdly, high temperature weather can also cause damage to photovoltaic cells. In high temperature weather, the temperature of photovoltaic cells will rise, leading to thermal expansion of photovoltaic cells and subsequently causing damage to them. This not only affects the effectiveness of photovoltaic power generation, but also increases the maintenance cost of photovoltaic power generation.

Therefore, regular water washing and cleaning of photovoltaic panels in summer is necessary. It can not only clean sand, dust, bird droppings, etc. to avoid hot spot effects, but also provide appropriate cooling for photovoltaic panels to ensure their power generation efficiency.

Fourthly, in summer, the working environment temperature of the inverter will be relatively high, so the efficiency of the inverter will be lower. We can install a rainproof sunshade above the inverter, or install the inverter in a covered area, while ensuring ventilation of the inverter.

Multifit Solar is a company dedicated to the research, production, and sales of photovoltaic products and photovoltaic operation and maintenance products. It has a large number of customers both domestically and internationally, and has been exporting for 15 years. It has solved the problems of power shortage and difficulty in operating photovoltaic power stations for customers, and has received good reviews from many customers.
