“Agricultural and photovoltaic complementation” is a new development model which uses solar energy on roofs to develop agricultural production inside sheds.
1. Agricultural photovoltaic supplementation makes it possible to produce clean energy through the construction of rooftop photovoltaic projects, which are ultimately integrated into the national grid. At the same time, photovoltaic technology is organically combined with modern physical agriculture within the project. shed to develop modern and efficient agriculture, which has both unlimited power generation capacity and no pollution and no additional land occupation, it can realize three-dimensional value-added use of land and achieve a win-win situation. winner for photovoltaic development and agricultural production. .
2. Mode: Photovoltaic energy production is generated externallylaugh of the shed and vegetables are grown inside the shed. In addition to the energy generated for use inside the hangar, the rest is integrated into the public electricity grid and benefits. subsidies from the national new energy production policy.
3. Several models and the advantages they bring:
Photovoltaic agricultural greenhouse for warm counter-season in winter
a. Fruits and vegetables require good thermal insulation effect in winter
b. Structure: The first rear wall is made of an earth wall to facilitate thermal insulation, the roof is made of a steel structure and solar panels and translucent glass are used instead of the commonly used plastic films.
c. Installation example: Solar modules are usually installed on the back of the roof, in three vertical rows, 100 meters long from east to west, and 10 meters wide from north. to the south, and transmitted itLight sion of the planting area is more than 80%

d Income: The roof covering an area of 1,000 square meters can install 75 kilowatt modules at one time. 30 degree angle, generating 90,000 hours of electricity per year. The total investment in the greenhouse and power generation system is around 800,000 yuan. The annual income from electricity generation is 108,000 yuan, and the net agricultural income is 80,000 yuan. The two annual income can reach 188,000 yuan.
Low light photovoltaic agricultural greenhouse
a. Purpose: to grow mushrooms and other low-light crops with low lighting requirements and high thermal insulation requirements
b. . Structure: The roof uses a steel structure and uses solar panels instead of the commonly used plastic films. As this type of greenhouse does not require transmission oflight, all solar modules are generally installed
c. Installation example: The greenhouse is 100 meters from east to west, 10 meters wide from north to south, and covers an area of 1,000 square meters. Modules can be installed on the roof. With 800 pieces of 250W components, the overall installed photovoltaic capacity of a greenhouse is 200 kilowatts, with an angle of 30 degrees, and can generate 240,000 kilowatt hours of electricity. annual
d. Income: The total investment in greenhouses and power generation system is 1.8 million yuan, and the annual power generation income is 288,000 yuan, the net agricultural income is 100,000 yuan and the two annual income can reach 388,000 yuan.
Photovoltaic agricultural greenhouse
a. Purpose: Livestock breeding, which is a model of a multi-span steel-framed greenhouse. This photovoltaic greenhouse model can maximize the utilizationland resources. The roof of the greenhouse is completely covered with solar modules and livestock breeding is carried out under the greenhouse.
b. Installation example: The greenhouse as a whole is composed of several units with a width of 8 meters from north to south and a length of 8 meters from east to west (the cleaning channel is 50 cm wide) . Three rows of components can be installed vertically on the sunny side of the greenhouse at a 30 degree angle.
