Background technique

In recent years, the global energy crisis and environmental pollution problems have frequently appeared. Energy conservation and emission reduction have also become the main theme of the times, and have promoted the development and application of new energy sources such as photovoltaics. Photovoltaic power generation is based on the principle of photovoltaic effect, using solar cells to convert sunlight directly into electricity. The rapid growth of the solar photovoltaic power generation industry is not only because it is a clean energy with many advantages, but also a more attractive reason is that in the process of integrating solar energy with buildings, solar battery modules are more compatible with buildings than solar water heaters. Solar cell modules can not only be used as energy equipment, but also as roofing and wall materials, which not only save energy in power supply, but also save building materials.

my country's greenhouse area is the largest in the world. Agricultural greenhouses have strict requirements on temperature, humidity, light, and air circulation. Different crops, economic crops or flowers in different seasons have different requirements for growth conditions. How to provide suitable for crops? The growing condition of the greenhouse is the key issue in the design of the greenhouse; the agricultural greenhouse has also become a development direction of the photovoltaic industry, and it is rising day by day. The photovoltaic agricultural greenhouse grows vegetables to generate electricity, but the solar panels installed on the roof will affect the sunlight in the greenhouse. penetration, and the shadows generated by it prevent some plants in the greenhouse from fully receiving uniform light, which affects the growth cycle of sun-loving plants. When there is more sunshine, the temperature in the shed is high, which is not conducive to the growth of plants. At present, extreme weather occurs frequently, with continuous rainstorms and dry weather alternately. When the rainstorms are continuous, it is easy to become waterlogged and affect the later growth of plants. Be careful in rainy seasons Ditch drainage, and in the case of drought in the critical period of crop water demand, spraying 1-2 times can increase crop yield and yield. How to balance the relationship between growth and regulation factors such as temperature, humidity, light, and air circulation is crucial to the development of agricultural greenhouses. Extension is crucial, and providing good growing conditions for crop planting is key for a good harvest.
