Prosperous photovoltaic agriculture

The laborers get their food. This is the greatest reward for workers. With the advancement of science and technology, the labor practices of today's land have also changed. When the combination of photosynthesis and photovoltaic effects collides, technology and tradition have emerged as the most beautiful sparks. This article will be presented to readers. When the sun generates electricity directly for agricultural production, the world is already very different.

First, solar photovoltaic agriculture shed in the future of the road to agriculture The country's largest greenhouse area in the world, in addition to open small and medium sized arch sheds and other simple equipment, the construction of solar greenhouses, plastic greenhouses up to more than 200 million hectares. For the photovoltaic industry, if these light-transmitting roofs are used abundantly, not only can they save a lot of field resources, but they can also use the greenhouse itself as a foundation for photovoltaic power generation. The established power resources can be directly supplied to applications such as lights, fill lights, shutters, irrigation facilities, and plant protection facilities in the greenhouse. It can also provide applications for production and survival of residents and farmers.

Agricultural photovoltaic greenhouses are such greenhouses that integrate solar photovoltaic power generation, intelligent temperature control, and modern high-tech planting. It is made of steel skeleton and covered with solar photovoltaic modules to ensure the lighting requirements of photovoltaic power generation components and the lighting requirements of the entire greenhouse. The direct current generated by solar photovoltaics directly supplements the agricultural greenhouses, and directly supports the normal operation of agricultural equipment in greenhouses, driving irrigation of water resources, at the same time solving greenhouse heating in winter, increasing the temperature of greenhouses and promoting rapid growth of crops.

The "marriage" between agriculture and photovoltaics has established a new model of "growing vegetables in sheds and power generation in sheds". Taking the solar greenhouse as an example, the daily power generation capacity of 120 panels installed on the top of the solar greenhouse can meet the electricity demand of various production equipment such as greenhouse curtains, wet curtain fan cooling systems, water and fertilizer integration, carbon dioxide generators, and plant growth lamps. The remaining power can be directly integrated into the grid through the grid-connected system. Photovoltaic agricultural greenhouses can not only improve the land utilization rate, solve the employment problems of farmers nearby, but also provide effective and large-scale demonstration of agriculture. The integration of sightseeing and eco-agriculture is a new type of agriculture project that integrates tourism to build sightseeing agriculture, integrates with the needs of community agricultural products, builds community farms, and combines the experience of citizens with the construction of happy farms, which integrates efficient planting, popular science and leisure tourism. .

Second, "fishing complement each other": lurking under the solar panels "shrimp soldiers will be"

For large-scale photovoltaic power plants, the western region with long sunshine hours and large areas of cheap desertification land is undoubtedly the first choice. However, due to the fact that the western region is far from the load center, the problem of abandoning photovoltaic power stations in some regions has not been solved well. While the development of photovoltaic power plants in the eastern region, although not connected to the grid, scarce land resources have become a barrier to the development of large-scale photovoltaic power plants. In view of this situation, the CPI Group has pioneered the "photovoltaic and fish-complementary" model of photovoltaic power plants, making it possible to develop large-scale photovoltaic power plants in the developed eastern regions represented by the Jiangnan Water Town.

What exactly is a "fishery-light complementary" photovoltaic power station? The so-called “fish-light complementary” photovoltaic power plant uses the abundant fish pond resources in the Jiangnan area and the reeds to develop photovoltaic power generation projects. It adopts the modes of water power generation and underwater culture, and has the potential to develop leisure tourism. The "fishery and light complementation" model has become a scale in Jiangsu, China. This model will give full play to the benefits of land and will play a good role in demonstrating the combined development of the comprehensive utilization of land in the country and the new energy industry.

III. Photovoltaic Water Conservancy Technology to Solve the Problems of World Water Use in Agriculture China's arable land area ranks fourth in the world, lagging behind the United States, Russia, and India. What is even more worrying is that there are 55% of water shortages and drylands in China's available arable land. It is a true portrayal of the lives of peasants in dry land. With the warming of the global climate, the weather is fickle, and the demand for irrigation equipment for agriculture is increasing day by day. How to solve the problem of agricultural drought and irrigation water shortage? In regions with well-developed infrastructure and complete power grids, this may be easily resolved. However, what are the places where the power grid is difficult to cover?

Photovoltaic water intake technology is a new type of water lifting technology that has been vigorously promoted in Yunnan Province in recent years and has a strong development momentum. In addition, a number of high-quality and successful application cases have been achieved in Yunnan, and the results are dazzling. “Solar photovoltaic water extraction technology” is an optical-mechanical-electrical integration system that has been rapidly developed in recent years. It utilizes long-lasting energy from the sun, absorbs solar radiation energy, and absorbs solar radiation energy through a series of solar cell arrays consisting of solar cell modules. Converted to electrical energy to power the entire system. Then through the photovoltaic lift inverter to control and regulate the operation of the system, convert the DC power generated by the solar array into AC power, drive the water pump, and adjust the output frequency in real time according to the change of the sunshine intensity to achieve maximum power point tracking. Use solar energy.

In China's 55% of dry and dry land, even if only 1% of the arable land adopts photovoltaic lift technology, it can form a 400GW installed market. And 1GW installed solar photovoltaic lift equipment can meet the water demand of 5 million to 10 million mu of land. Compared with the large amount of electric power laying, reservoir construction, and digging required for traditional water conservancy construction, the overall investment scale of the two projects varies greatly. The significance of global eco-environmental friendly brought about by photovoltaic water conservancy makes it more advantageous.
