Why is the photovoltaic industry combined with agriculture?
[China Agricultural Machinery Industry News] According to incomplete statistics, China's solar greenhouses and plastic greenhouses cover more than 2 million hectares. If developed and utilized, the domestic photovoltaic agriculture market will reach a trillion scale within five years. According to relevant information, China's PV installed capacity will surge by 63.5% this year, and the growth rate will exceed 60% of last year. In the past two years, relevant national ministries and commissions have also issued a series of policy measures to promote the healthy development of the photovoltaic industry, promote the construction of distributed photovoltaic power generation application demonstration zones and photovoltaic poverty alleviation pilot projects.
Photovoltaic agriculture is not yet mature 2025 PV subsidies are being revoked
　　
Greater use of resource efficiency
The combination of agricultural greenhouses and photovoltaic power generation is a kind of resource integration. The construction of photovoltaic power plants does not need to change the nature of the land. The planting industry can use the high-quality agricultural greenhouses built by the photovoltaic power station investors free of charge, while the PV power plant investors do not need to bear up to 20 Years of land transfer rent.
“I have now built 3 acres of land in my home into a solar greenhouse. The electricity generated can not only be used for self-use, but also sold to the country to make money. In addition, I can grow vegetables in solar greenhouses. Several times.†Farmers who have built a photovoltaic industry say so.
Great market prospects and considerable economic benefits
With the continuous innovation and development of photovoltaic application technology, the emerging industry of photovoltaic agriculture has reached the market scale of 100 billion yuan every year. Some forecasters even believe that the market scale may reach trillions in the next five years.
Different from the single profit model of photovoltaic power plants or agricultural greenhouses, photovoltaic agriculture takes the dual profit path of electricity and agricultural products, and the benefits are considerable. According to Sun Mingliang, general manager of Huatian New Energy Group, the investment in each greenhouse is 300,000 yuan, and the total investment of the project is 9 million yuan. Each year, the project can generate 1.2 million kilowatt-hours of electricity and the electricity sales benefit is 1.4 million yuan. Vegetable planting, sightseeing and picking can realize a profit of 500,000 yuan per year and a total profit of 1.9 million yuan. A simple photovoltaic power plant generally recovers profits in 8-10 years, while a photovoltaic agricultural greenhouse can recover costs and achieve profitability in about 4-5 years. Based on the 25-year lifespan, the profitability of the photovoltaic agriculture project is very significant.
The industry is still immature, and the concerns remain.
“Photovoltaic projects are increasingly using agricultural project enclosures, 90% of which are declared as 'species of mushrooms'. The main reason for this phenomenon is that there is too much crossover between photovoltaics and agriculture. PV people don't understand agriculture. The design of a mountainous edible fungus production base in Henan is actually a large mountain patch. The 1000-mu agricultural greenhouse of a state-owned enterprise in Jiangsu has been connected to the grid, but the grass is under the greenhouse. ......"
Not long ago, the experts of China's photovoltaic agricultural industry technology innovation strategic alliance and the efforts of professional photovoltaic agricultural enterprises passed the standards in China's approval of photovoltaic agriculture.
These standards include: "Technical Guidelines for Photovoltaic Agricultural Systems", "Photovoltaic Agricultural Terms and Symbols", "Yuguang Integrated Pond and Park Construction, Aquaculture Management Technical Specifications", "Photovoltaic Kiwi Orchard Technical Guidelines", "Photovoltaic Oil Peony" "Technical Guidelines for the Park", "Code for Design, Construction, Acceptance and Maintenance of Photovoltaic Agricultural Power Station Systems".
At present, the state has a series of subsidy policies for photovoltaic agriculture. The photovoltaic industry has invested heavily in the early stage, and some people will also worry that the PV subsidy will be suddenly cancelled.
Li Ding'an, an expert at the Institute of Electrical Engineering of the Chinese Academy of Sciences, said that the state is very supportive of such distributed photovoltaic power generation. The electricity generated by the current technology has reached the standard for input to the national distribution network. As for subsidies, Li Dingan believes that as the cost of photovoltaic power generation declines, the price of subsidies will be adjusted. “The general trend is to withdraw this subsidy around 2025 and fully enter the market.†At the “2015 China PV Summit†held in October 2015, Liang Zhipeng, deputy director of the New Energy and Renewable Energy Department of the National Energy Administration, revealed that PV Subsidies will not stop in the next 8 to 10 years.
