Photovoltaic agricultural shed projects are promising

According to relevant information, China's installed photovoltaic capacity this year will surge by 63.5%, which will increase by more than 60% last year. Such a large-scale construction will bring great benefits to the upstream and downstream companies in the photovoltaic industry chain.

In addition to this, relevant national ministries and commissions have successively introduced a series of policies and measures such as promoting the healthy development of the photovoltaic industry, advancing the construction of demonstration areas for distributed photovoltaic power generation and photovoltaic pilot projects for poverty alleviation, and building a complete industrial policy and management in a short period of time. The system has exerted a positive influence and driving effect on China's photovoltaic and agricultural industries.

Among these, the promotion of photovoltaic agricultural greenhouses is undoubtedly an optimal model for achieving double-utilization of clean energy and modern agriculture. Photovoltaic agricultural greenhouses are greenhouses integrating solar photovoltaic power generation, intelligent temperature control systems, and modern hi-tech planting. The electricity generated not only supports the irrigation, temperature control, and light-filling functions of the greenhouse plant, but also meets the electricity demand of the greenhouse. It can also sell the remaining electricity to the power grid company to generate profits for the investment company. The good thing.

Compared with the construction of centralized large-scale photovoltaic ground power stations, the photovoltaic agricultural greenhouse project has the advantages of saving land resources and maintaining the nature of land use. It can effectively reverse the conflicts caused by increased population and reduced farmland, and promote the sustainable development of the social economy. On the other hand, photovoltaic sheds built on the original arable land can not only flexibly create an environment suitable for the growth of different crops, but also find a new path for the development of specialized and large-scale industries such as green organic agriculture and tourism agriculture, and through the realization of agricultural science and technology, Industrialization will surely become a pillar industry of regional agricultural efficiency and farmers' income increase.

It is estimated that the total investment required for a photovoltaic agricultural greenhouse project with a capacity of 20,000 kilowatts will be about 249.41 million yuan, and the annual generating income will be 30.576 million yuan. After completion, if the rental or self-managed management model is adopted, the investment recovery period will be about 10 years; if the project is fully integrated into the grid, the company can still maintain an internal rate of return of more than 8% after paying the cost of the photovoltaic greenhouse land. .

Therefore, the development of photovoltaic agricultural greenhouses is not only an effective way to promote green agricultural production and realize high-tech science and technology, but also a major measure to solve the domestic PV industry dilemma. Once launched, it has been favored by the photovoltaic industry. According to statistics, as of the end of 2013, the installed capacity of the agricultural photovoltaic and Fishing Light complementary projects approved by the state has reached 2.9 million kilowatts. At present, more than 2 million kilowatts of photovoltaic agricultural projects have been under construction or have been signed. More than 400 large-scale photovoltaic vegetable greenhouses, “fish and water complement” aquaculture, and photovoltaic livestock and poultry breeding shed projects have reached more than 400 in the country. Experts in the industry believe that if large-scale and large-scale promotion of photovoltaic agricultural products is implemented across the country, the short-term market can reach 100 billion yuan, and it can reach a trillion yuan scale within five years. The market prospect is extremely broad.

Due to the current lack of special planning and coordination of the agricultural photovoltaic industry, large initial investment, and some technical problems, there are still difficulties in the promotion and popularization of photovoltaic agricultural greenhouses. In response to this bottleneck problem, the author believes that solutions should be sought from the following aspects: First, deepen the domestic application market, combine the practical characteristics of the intensive construction of China's major cities, and the limited application space of distributed photovoltaics in cities, to develop photovoltaic agricultural greenhouses. At the entry point, the photovoltaic power generation will be expanded to rural areas and agricultural fields to promote green agricultural production and realize efficient and scientific recycling ecological agriculture. The second is to conduct full data analysis on the geographical, natural conditions, and electrical energy utilization factors of the agricultural photovoltaic greenhouse, which is the power linkage project, and to verify it scientifically in practice to find the best development path. The third is to formulate special plans for the agricultural photovoltaic industry, deepen regional cooperation, build a complementary model of regional economic advantages, introduce leading enterprises to develop photovoltaic agricultural demonstration pilots, integrate agricultural activities, demonstrations of science and technology, and exert industrial cluster effects to promote PV agriculture to Industrialization, scale of progress. The fourth is to increase the research and development of key technologies in photovoltaic agricultural greenhouses and the training of relevant talents, and to strengthen the analysis and evaluation of the operational status of photovoltaic agricultural greenhouses that have been built, so as to provide technical support for large-scale and large-scale implementation of photovoltaic agricultural greenhouses. The fifth is to strengthen policy support and raise the subsidy standard. Distributed PV has a wide range of applications and broad prospects for development. In addition to providing support for project approvals and approvals, the State should also differentiate between subsidy funds, and provide additional subsidies for projects with high initial investment but significant social benefits. . And allow to enjoy agricultural science and technology innovation, agricultural restructuring and agricultural environmental protection and other subsidies.
