The wonderful chemical reaction of "photovoltaic + agriculture"

Photovoltaic agriculture is a new type of agriculture that widely applies solar power generation to modern agricultural planting, breeding, irrigation and other fields. On the one hand, solar photovoltaic system can use agricultural land to generate electricity directly and at low cost. On the other hand, due to the good light transmittance of thin film solar cells, most of the light sources needed for plant growth, such as red light and infrared light, can penetrate, store heat energy, increase the greenhouse temperature, which is beneficial to plant growth in winter and save energy.

Now, the new combination of "photovoltaic + agriculture" has been used in many fields, such as agricultural greenhouse, animal husbandry roof, fish-light complementary and grazing-light complementary, bringing a new agricultural management model for farmers.

Photovoltaic agricultural greenhouse

Agricultural greenhouse is the most widely used management mode in the practice of transforming agricultural production environment. While realizing the function of traditional greenhouse, photovoltaic agricultural greenhouse can also ensure the intelligent management of greenhouse through solar power generation, and realize the integration of modern high-tech and traditional agricultural planting. Thin film solar photovoltaic greenhouse, the application of Hanergy transparent electrode film module can be high transmission of red light, infrared, and uniform light transmission, does not affect crop growth, while ensuring solar power generation and the lighting needs of crops in the greenhouse, it can be widely used in flower, vegetable planting and seedling breeding. The electricity generated by solar energy can support the irrigation system of the greenhouse, supplement light to the plants, solve the heating demand of the greenhouse in winter, increase the temperature of the greenhouse, and promote the growth of crops.

The weight of the thin film photovoltaic agricultural greenhouse power generation module is equal to that of the agricultural materials, and it can be perfectly combined with the greenhouse, properly shaded, and increase the income of power generation without additional land occupation, thus forming a new pattern of parallel benefits of photovoltaic power generation, energy saving and emission reduction, land saving, agricultural production increase and farmers' income increase. On the other hand, the use of photovoltaic agricultural greenhouse is conducive to the development of integrated ecological projects with the combination of modern agriculture and tourism, and improve the economic income of agricultural investors.

Animal husbandry roof

While improving the growing environment for plants, the combination of photovoltaic and agriculture can also provide more "livable" accommodation for poultry and livestock. The photovoltaic modules installed on the livestock roofs of the farms bring the benefits of killing many birds with one stone. The animal husbandry roof with photovoltaic power station, on the one hand, can use the limited space to generate electricity, provide electricity for the farm, meet the daily electricity needs of the farm, and ensure the power consumption of cooling, dehumidification, ventilation and other equipment in the farm, and create a living environment with suitable temperature, humidity, no discharge and no smell for poultry and livestock. On the other hand, the characteristics of sunshade and heat absorption of thin film solar cells can be used to bring coolness to the farm in summer and further save electric energy.

Fishing and light complementary

Combined with the characteristics of many river and lake wetlands in eastern China, photovoltaic agriculture has also produced a new photovoltaic application form of complementary fishing and light. As the name implies, fishing and photovoltaic power generation is a combination of fishing and photovoltaic power generation, through the establishment of battery panels on the surface, under the surface planning of fish and shrimp culture, to achieve the parallel mode of breeding and power generation, realizing the dual use of one place. This method greatly improves the utilization efficiency of land or water surface, and increases the output value of land per unit area. Through the three-dimensional support, one side of the photovoltaic panel "floats" on the water, and the fish pond turns into a photovoltaic power station.

"the upper can generate electricity and the lower can raise fish". The complementary fishing and light can reduce the culture cost and the environmental temperature of the water surface, and form a good sunshine, ventilation and cooling environment, which is conducive to prolonging the life of photovoltaic modules and improving the power generation efficiency of photovoltaic modules. it has opened up a new way for the comprehensive development of new energy industry in areas with dense river networks.

Animal husbandry and light complementary

It is also feasible in animal husbandry to improve the operation efficiency through the application of photovoltaic power station. As photovoltaic power stations are mostly built on idle land such as Gobi and desert, planting forage under the solar panels of photovoltaic power stations can promote the efficient use of land resources, prevent wind and fix sand, improve soil erosion and conserve water sources. The green barrier formed by vegetation can also improve the surrounding environment of photovoltaic power station and reduce the loss of photovoltaic power station caused by wind and sand. Through this "one grass, two uses" model, the final realization of photovoltaic industry to drive ecological construction.

In the fields of agriculture, animal husbandry and fishing, the combination of "photovoltaic + agriculture" has produced wonderful chemical reactions, making three-dimensional use of space, generating clean electricity, expanding the proportion of renewable energy for power supply, and promoting green agricultural production. to achieve a technologically efficient circular ecological agricultural production model. Photovoltaic agriculture can not only provide convenience for agricultural production, but also improve the level of agricultural science and technology, improve the lives of farmers and accelerate the transformation of rural areas. Modern agriculture needs the support of photovoltaic technology, and the application value of photovoltaic products in agriculture is also inestimable. promoting the development of photovoltaic agriculture is a win-win way to develop modern agriculture and photovoltaic industry.
