Developing photovoltaic agriculture to accelerate the efficient development of ecological agriculture

[ China Agricultural Machinery Industry News ] "Traditional agricultural operation mode can no longer meet the needs of modern ecological agriculture development. China's photovoltaic agricultural resources are very rich, and the market prospect is very broad. The combination of photovoltaic and agriculture is a great opportunity to accelerate the development of ecological agriculture. Governments at all levels attach great importance to the comprehensive utilization of photovoltaic resources, actively introduce encouragement and support policies, and vigorously develop the photovoltaic agriculture industry with remarkable results. At present, China has achieved remarkable results in the fields of photovoltaic agricultural greenhouses, maturity and light complementation, fishing and light complementation, and photovoltaic irrigation systems. For example, in the large-scale and large-scale promotion of photovoltaic agricultural products in the country, its market output value can reach 100 billion yuan, and it can reach a scale of one trillion yuan within five years," said Zhang Yong, president of China Photovoltaic Agricultural Working Committee.

Developing photovoltaic agriculture to accelerate the development of ecological agriculture

Zhang Yong believes that photovoltaic agriculture can only be truly healthy and sustainable if it is based on agriculture. The development of photovoltaic agriculture not only solves the problem of land demand for photovoltaic power plants, but also brings additional income to farmers while taking into account crops without reducing production, and leads farmers to make big money.

"The advantages of photovoltaic agriculture are the above power generation, planting and breeding below, and power generation and cultivation." Zhang Yong said that the photovoltaic agriculture integrated grid-connected power generation project will plant and culture solar power and modern agriculture. The combination of facilities and agriculture can not only use farmland to directly generate electricity at low cost, but also use light energy resources to store heat energy, increase greenhouse temperature, and conducive to the growth of animals and plants to save energy.

According to incomplete statistics, China's solar greenhouses and plastic greenhouses cover more than 2 million hectares. If developed and utilized, the domestic PV agriculture market will reach a trillion scale within five years. Different from photovoltaic power plants or agricultural greenhouses, the photovoltaic model is a dual profit path for electricity and agricultural products, and the benefits are considerable. Sun Mingliang, general manager of Shandong Huatian New Energy Group, calculated the account for the reporter. Each investment in the photovoltaic agricultural 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 to 10 years, while photovoltaic agricultural greenhouses can recover costs and achieve profitability in about 4 to 5 years. Based on the 25-year lifespan, the profitability of photovoltaic agricultural projects is very significant.

"The significance of developing photovoltaic agriculture can not only enable farmers in remote areas to generate electricity by themselves, but also transform traditional farmers into industrial new-type professional farmers." Zhang Yong said that photovoltaic agriculture projects have become irreplaceable for domestic modern agricultural development. Promoting the role of the photovoltaic industry, the traditional agriculture turned gorgeous, injected high-tech factors, adding vitality to the development of modern ecological agriculture.

"In the future, photovoltaic greenhouses can realize automatic detection of temperature, humidity, soil moisture, pest control, etc. in the shed, saving labor and electricity, producing controllable and pollution-free ecological agricultural products, and selling electricity to make money. The combination of photovoltaics and agriculture has produced economic benefits." Zhang Yong said.
