Photovoltaic Energy in the Grain Rain Season

   Grain Rain is the sixth solar term in the twenty-four solar terms and the last solar term in spring. It begins around April 20 of the Gregorian calendar every year when the sun reaches 30 degrees of ecliptic longitude. There are some significant characteristics before and after the Grain Rain season, such as increased rainfall and higher temperatures, which also have a certain impact on agricultural activities. The Grain Rain season is a critical period for spring ploughing and sowing, and farmers from all over the country are very busy. There are also many aspects of the relationship between Grain Rain and photovoltaics, as follows:

Light conditions

    Grain Rain is usually in the transition stage from spring to summer, the weather gradually warms up, the sunshine time increases, and the intensity increases. For photovoltaic power generation, sufficient light is the basic condition for power generation. The light at this time is conducive to the power generation efficiency of photovoltaic modules, increases power generation, and is the peak stage of photovoltaic power generation.

Construction holiday

   The temperature during the Grain Rain season is relatively suitable. It is neither as cold as winter nor as hot as summer, often accompanied by heavy rain and other severe weather. It is very suitable for the construction of photovoltaic projects. Whether installing photovoltaic modules, laying lines or debugging related equipment, construction workers can work more comfortably and efficiently, reduce safety risks caused by weather factors, and help photovoltaic projects to proceed smoothly.

Equipment maintenance

    The spring rain during the Grain Rain season can clean the dust and impurities on the surface of photovoltaic modules, so that photovoltaic modules maintain good light transmittance and power generation performance, and reduce the frequency and cost of manual cleaning.

"Photovoltaic + Agriculture" model

   Grain Rain is an important solar term for agricultural production. "Rain produces hundreds of grains". At this time, the increase in precipitation is conducive to the growth of crops. In this model, it also provides a suitable environment for agricultural planting under the shed, driving the upgrading of the agricultural industry. For example, in some photovoltaic tea gardens, tea grows vigorously during the Grain Rain season, and photovoltaic facilities not only provide shading and other functions, but also their power generation benefits can bring additional income to the tea garden.
