What are the technologies of photovoltaic agriculture?

With the large-scale development of photovoltaic agriculture, photovoltaic technology plays an increasingly important role in agriculture. The so-called photovoltaic agriculture is a combination of solar power generation, modern agricultural planting and breeding, and efficient facility agriculture. On the one hand, solar photovoltaic system can use agricultural land to generate electricity directly at low cost; On the other hand, because a major feature of thin-film solar cells is that they can be made transparent, the main light sources needed for animal and plant growth can penetrate; In addition, infrared light can penetrate, store heat energy, raise the temperature of greenhouse, which is beneficial to the growth of animals and plants and save energy in winter. The following are some of the latest photoelectric agricultural technology applications:

Multifunctional agricultural facilities integrating photovoltaic power generation and characteristic spectrum led lighting.

The utility model relates to an agricultural facility, in particular to a multifunctional agricultural facility integrating photovoltaic power generation and characteristic spectrum led lighting, which comprises a greenhouse with a ceiling and side walls, and is characterized in that a spectral thin-film solar panel is arranged on the ceiling of the greenhouse, and the solar panel can absorb the light in the short wavelength band (below 570nm) of sunlight and transmit part of the light in the long wavelength band (above 600nm), so that photovoltaic power generation can be carried out at the same time, and the required illumination can be provided for cultivated plants. There is a characteristic spectrum led lamp in the greenhouse, and the spectrum and half-wave width of light emitted by the characteristic spectrum led lamp are suitable for the characteristic spectrum of cultivated plants to meet the needs of plant growth. The facility is not only energy-saving and electricity-saving, but also conducive to plant growth and improve the yield and quality of agricultural products.

Trapping and killing device for solar crop pests

The invention relates to a trap and kill device for crop pests, which takes solar energy as a source of electric energy and heat energy and has dual functions of physics and biology. According to patent search, the invention is currently in the leading position in the world.

This technology includes photovoltaic power generation technology, solar photothermal technology, light sensing three-position tracking technology, high voltage discharge technology, semiconductor ultraviolet emission technology and insect sex hormone release technology. Through an independent solar energy system, the invention can automatically track solar power generation in the field, accumulate electric energy through a specially designed energy storage device, and collect and store the heat energy generated by the photocell. At night, the system automatically starts the black light generator and high-voltage electrical appliances to trap and kill phototaxis pests, and at the same time opens the sealed container of sex hormones invading pests in hot water, so that the sex hormones slowly and evenly volatilize and spread, and a large number of phototaxis pests and pests attracted by sex hormones pounce on the device and touch the high-voltage line outside the device to kill them, so that a large number of pests can be killed.

Household self-sufficient roof photovoltaic power generation system equipment

This technology combines the high permeability and self-cleaning of nano-composite film into one and applies it to lighting glass. It is planned to invest 5 million yuan, and the goal is to apply this product to solar cover glass, which can significantly improve the photothermal and photoelectric conversion efficiency of solar products.

This technology aims to study the key component of solar street lamp-LED lamp holder and the technology to reduce the energy consumption of the whole system. Its goal is to use this product on a large scale in enterprises and projects, so as to save energy, reduce consumption and protect the environment. The application of this technology has made a major breakthrough. This technology has the characteristics of industrialization.

Photovoltaic water pump

Photovoltaic water pump system is an optical, mechanical and electrical integration system that has developed rapidly in recent years. It uses the electric energy generated by solar cells to drive DC permanent magnet motor or high-efficiency asynchronous motor to drive high-efficiency water pump after maximum power point tracking, conversion and control. The system can be used in farmland irrigation, landscape fountains, fish pond oxygenation, highway greening, water supply and drainage of coastal saltworks and other fields. In today's energy shortage, the popularization and application of this technology will certainly produce good economic and social benefits.

Solar photovoltaic broad-spectrum insecticidal lamp

The utility model discloses a solar photovoltaic broad-spectrum insecticidal lamp, which comprises a solar panel and a storage battery installed on an upright post, wherein the lamp body of the insecticidal lamp is hung on the upright post, a power grid is arranged around the lamp body, an insect catching bag is arranged below the lamp body, and a lamp tube connected with a frequency conversion controller is arranged in the middle of the lamp body. Due to the adoption of the above structure, the starting lamp tube connected with the frequency conversion controller of the utility model can trap different kinds of pests in different environments, which has great lethality to pests and wide target range, and the frequency can be controlled according to the size of the site, so that the insecticidal lamp can achieve the best working efficiency.
