Photovoltaic analysis of the agricultural extension model

Polaris solar PV net news: first, the PV agricultural prospects

With the national authorities in the continued attention and support of new energy, photovoltaic power generation in a new climax in domestic applications, a lot of social capital of enterprises and the influx, PV Application market increased gradually. Meanwhile, available PV power station construction wasteland, barren hills, wasteland, and the roof and other less, have been far from enough to meet the market needs, photovoltaic PV of this groundbreaking new industries of agriculture products used in agriculture, fisheries, aquaculture, agriculture, Tourism tourism.

PV photovoltaic power generation and agricultural production in agriculture is combined roof solar power, Studio developing new photovoltaic systems engineering in agricultural production, is a new mode of modern agricultural development. Through agricultural production, ecological protection and photovoltaic power generation, combining tourism and pastoral landscape, agricultural production and agricultural ecological environment and ecological agriculture management model, raise the unit output of land, increase farmers ‘ income, in order to maximize the use of resources, increase of ecological and social benefits.

Second, the advantage of PV agriculture

PV agriculture is the traditional farming combined with photovoltaic power generation technology research and develop a new generation of photovoltaic power generation project. Shed roofs formed by the solar components, and white glass installation. Has a valid filter light, is harmful to the crops do not affect crops absorb sunlight for photosynthesis, inside temperature and humidity smart control. Outside solar power, greenhouse for growing vegetables, electricity generated by inter alia for Studio use, the allowance into the public power grid, enjoy the State policy of subsidizing new energy power generation. PV integration in agriculture, green and low-carbon dual pattern, a greenhouse is a biomass power plant.

Third, the photovoltaic characteristics of agricultural integration

1, the effective use of agricultural greenhouse roof, without occupying new land resources, belonging to the high efficiency facility agriculture projects;

2, greenhouses can be used for 25 years, long service life than traditional greenhouses, no film year, avoid repeated construction caused by waste of resources;

3, ultra clear tempered glass and solar modules improve their overall greenhouse insulation;

4 install solar insects-killing light, greenhouse, livestock, reducing the use of pesticides, and helps to improve the quality of agricultural products;

5, Studio using solar-powered LED fill light, extend the time, shorten the growth period;

6, temperature and humidity smart control, create a comfortable environment conducive to crop growth, increasing agricultural production;

7 sprinkler/drip irrigation, using the international advanced technology, electric operation is easy to use, save effort of mind;

8, green, environmental protection in line with the national ecological civilization and social development.

Four, PV extension model of agriculture

PV agriculture based on the different categories of agricultural production is divided into four modes:

1, winter-season solar agricultural greenhouses

Winter-season solar agricultural greenhouse grown mainly in-season fruits and vegetables dish, require a good winter thermal effect, such as with traditional vegetable greenhouse in greenhouse shed, rear wall wall insulation, roof steel structure, the use of solar panels and translucent glass instead of plastic sheeting commonly used. As this mode of greenhouses require high illumination time, solar component is typically installed on the rear of the roof, install three rows of vertical, 100 meters long, 10 meters wide North and South, cultivation zones transmittance 80%, covers an area of 1000 square meters of ceiling mounting kit 75-kilowatt, angle of 30 degrees, annual power generation at 91,000. Greenhouses and solar power generation system with a total investment of about 800,000 yuan, power generating annual revenues of $ 108,000 dollars, net farm income of 80,000 yuan, two income years up to 188,000 yuan.

2, low light solar agricultural greenhouses

Low light photovoltaic main agricultural greenhouses growing fungi such as low light crop, low light, high insulation requirements. This greenhouse shed roof steel structure, using solar panels instead of commonly used plastic film. Since this schema shelters do not need light, solar panel is usually installed, shed 100 meters, 10 meters wide North and South, covering an area of 1000 square meters of ceiling mounting kit 800 250W components, total PV installed capacity of 200-kilowatt in a shed, an angle of 30 degrees, years of power generation at 240,000-kilowatt. Greenhouses and solar power generation systems with total investment of 1.8 million dollars, generating income of 288,000 yuan, net farm income of 100,000 yuan, two income years may reach 388,000 yuan.

3, PV farmed agricultural greenhouse

PV agricultural greenhouses in farming mainly livestock, is a multi-span greenhouse steel structure mode. Photovoltaic greenhouses the pattern to maximize the use of land resources, canopy cover solar module, carried out under greenhouse farming. Greenhouse as a whole consists of a number of North-South width of 8 metres, length 8 m unit (cleaning channel of 50 cm wide), with greenhouses to install three rows of vertical component of face, angle to 30 degrees. 250W components can be installed in each unit 24, 6-kilowatt/cell. Can one megawatt per 30 acres, the year when power 1.2 million-kilowatt 1MW sheds and power systems with a total investment of 9.5 million Yuan, generating annual revenue of 1.44 million Yuan, rented breeding shed 30,000 yuan per MU, 1MW earned 600,000, two income years up to 2.04 million Yuan.

4, Yue Kwong complementary agricultural greenhouse

Complementary agricultural big canopy is mainly for fish farming and fisheries, fish ponds, lakes, water in the original installation of photovoltaic power generation system, through improved structures, without affecting the surface engaged in fish farming operations, but also ensures the generation effect, is a new type of solar energy utilization patterns. This pattern usually made open, the surface pile as a support, the whole consist of several North-South width of 8 metres and 8 metres in length units, shed you can install three rows of vertical component of face, angle to 30 degrees. 250W components can be installed in each unit 24, 6-kilowatt/cell. Can one megawatt per 20 acres, the year when power 1.2 million-kilowatt 1MW power generation system with a total investment of 9 million Yuan, generating annual revenue of 1.44 million Yuan, renting 50,000 yuan per Mu in breeding shed, 1MW earned 6 million, earnings two years up to 2.44 million Yuan.
