Introduction to photovoltaic agriculture, introduction to photovoltaic projects

The photovoltaic agriculture integrated grid-connected power generation project combines solar power generation, modern agricultural planting and breeding, and high-efficiency facility agriculture.

The complementary photovoltaic power generation projects are:1.Agriculture and photovoltaic complementation.

Agriculture and photovoltaic complementation to achieve clean energy through the construction of rooftop photovoltaic projects.

Generate electricity, which is eventually integrated into the national grid.

At the same time, the photovoltaic technology and modern physical agriculture will be organically combined under the shed to develop modern and efficient agriculture, which not only has the power generation capacity of no pollution and zero emission, but also does not occupy additional land, which can realize the three-dimensional value-added utilization of land and achieve a win-win situation of photovoltaic development and agricultural production.

2.Forest and light complement each other.

Forest-light complementation is in photovoltaic panels.

The open space is interplanted with red-leaved heather.

Seedlings can not only help poor households increase their income through photovoltaic power generation, but also increase the collective economy of poor villages through seedling planting.

income, to achieve photovoltaic power generation and seedling planting.

3.Fishery and light complement each other.

"Fishery and photovoltaic complementation" refers to the combination of fishery breeding and photovoltaic power generation, the erection of photovoltaic panel arrays above the water surface of fish ponds, the waters below the photovoltaic panels can be used for fish and shrimp farming, and the photovoltaic array can also provide good shielding for fish farming, forming a new power generation model of "power generation on the top and fish farming on the bottom".

Photovoltaics, photovoltaic, are the use of semiconductor materials, generally silicon materials, and also use cadmium telluride. These materials have a special photoelectric effect, which converts photons into electrons and converts sunlight radiation energy directly into electrical energy.

Photovoltaic industry refers to the general term of enterprises that provide raw materials, batteries, components and systems and ancillary products required for industrial development around the solar photovoltaic effect, and the photovoltaic industry in a broad sense can also include the subsequent parts of power generation, such as power grids.

According to Shi Lishan, deputy director of the New Energy Department of the National Energy Administration, at present, China's photovoltaic industry, the output of photovoltaic cells accounts for 40% of the world, and has become the world's most important photovoltaic cell production base, and the photovoltaic power generation market is also accelerating. Last year, more than 100,000 kilowatts of large-scale photovoltaic power stations were built.

The brief introduction of the photovoltaic project is as follows:

It is a plant engineering that uses solar power generation, and the key element of this technology is solar cells. Solar power generation refers to solar photovoltaic power generation, referred to as photovoltaic. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface.

Photovoltaic power generation system:

Off-grid photovoltaic system, off-grid photovoltaic power station includes village power supply system in remote areas, solar household power supply system, communication signal power supply, cathodic protection, solar street lamp and other leaky sock photovoltaic power generation systems with batteries that can operate independently.

Grid photovoltaic system, photovoltaic power generation example: Grid-connected photovoltaic power generation system is a photovoltaic power generation system that is connected to the power grid and transmits power to the power grid. It can be divided into grid-connected power generation systems with and without batteries. The grid-connected power generation system with a battery is dispatchable and can be incorporated into or out of the grid as needed, and also has the function of backup power supply, which can provide emergency power when the grid is out of power for any reason.

1. Photovoltaic is an industry about new energy.

2. Photovoltaic industry, referred to as PV, refers to the use of photovoltaic effect, so that sunlight irradiates silicon materials to generate electric current to directly generate electricity, and the industrial chain formed by the application and development of silicon materials is called "photovoltaic industry", including the production of high-purity polysilicon raw materials, solar cell production, solar cell module production, and related production equipment manufacturing.

3. Photovoltaic power generation is a technology that directly converts light energy into electrical energy by using the photogenerated volt effect at the semiconductor interface. The key element of this technology is the solar cell. Solar cells can be encapsulated and protected in series to form large-area solar cell modules, and then combined with power controllers and other components to form photovoltaic power generation devices.

The advantage of photovoltaic power generation is that it is less geographically restricted, because the sun shines on the earth; The photovoltaic system also has the advantages of safety and reliability, no noise, low pollution, on-site power generation and power supply without fuel consumption and transmission lines, and short construction period.

Agricultural and photovoltaic complementation, also known as photovoltaic agriculture, is the use of solar photovoltaic power generation pollution-free zero emission characteristics, and high-tech greenhouses organic combination, in the greenhouse part or all of the sunny surface of the laying of photovoltaic solar power generation device, it not only has the power generation capacity, but also for crops, edible fungi and animal husbandry to provide a suitable growth environment, in order to create better economic and social benefits, mainly photovoltaic agricultural greenhouses, photovoltaic breeding greenhouses and other modes.

From the perspective of combing the development of China's photovoltaic application market, the early development of ground power stations in the west has extended to the promotion of distributed photovoltaic power stations in economically developed areas in the southeast.

Agricultural production and power generation complement each other

Crops need to grow the light and photovoltaic power generation needs different light waves, photovoltaic solar greenhouse can achieve power generation and planting is not wrong, because the solar cell module will cause a certain shading, each greenhouse can be based on the light needs of different crops, using different installed capacity design, to meet the needs of plant photosynthesis for light.

For example, Mingchang bitter gourd, the growth process does not have high requirements for light transmittance, you can use crystalline silicon solar cell modules, install more battery modules, improve the installed capacity and generate more electricity; Nightshade vegetables such as colorful peppers and tomatoes with high light requirements are covered with improved solar coarse plexus energy cell modules with good light transmittance, reducing the installed capacity and enhancing light transmittance.
