What photovoltaic applications can benefit farmers?
1, agricultural photovoltaic greenhouse
Photovoltaic agricultural greenhouse power generation does not occupy the ground, nor will it change the nature of land use, so it can save land resources. It can play an active role in effectively reducing the large number of cultivated land under the large population increase. On the other hand, the PV project construction in the original agricultural land, land quality, conducive to the development of modern agricultural projects, the development of modern agriculture, agriculture is conducive to supporting the industry and the second, third industry combination. And it can directly raise the income of local farmers. In addition, the use of roof power to meet the needs of agricultural greenhouse, such as temperature, irrigation, etc. can also be lighting lighting, power grid sales to Power Grid Corp, with state subsidies, to achieve income.
2, the photovoltaic pumping system
China's agricultural terrain, irrigation area, irrigation is needed in every drought, rural power load together around the Internet, caused a lot of pressure on the already very tense because of power grid, agricultural irrigation and reduce phenomenon often appear without security. The emergence of agricultural photovoltaic pumping system to solve this problem, reduce the agricultural water conservancy and electric energy transmission construction cost, expand the scope of supply, completely solve the remote mountainous areas without electricity shortage areas and agricultural problems of hydropower. Now, in the agricultural irrigation field in our country, to daily irrigation has been very common use of solar photovoltaic pumping system.
3, photovoltaic street lamp
That is, people familiar with the solar street lamps, in the rural areas throughout the construction of beautiful, photovoltaic street lamps have been widely used. It can be said that photovoltaic street lamps are suitable for rural photovoltaic products, there are four main advantages:
Convenient installation and provincial expenses. When the utility model is installed, the complicated circuit is not needed, only a cement base is made, a battery pit is used, and the zinc bolt is used for fixing. It does not need to consume a lot of manpower, material resources and financial resources.
Maintenance cost is low, primary investment and long-term benefit. Because the circuit is simple, maintenance costs are not generated, and expensive electricity charges are not generated. 6-7 years to recover costs, 3-4 years to save about 1000000 of the electricity and maintenance costs. But the city circuit lamp electricity charge is high, the line is complex, needs the long-term uninterrupted line overhaul.
Energy saving and environmental protection. Photovoltaic street lamps utilize natural light sources in nature, reducing the consumption of electrical energy, pollution-free and non radiation, and meeting the concept of modern green environment protection.
Safety. City Electric lighting street lamps may exist because of the construction quality, material aging, power supply and other reasons caused by the hidden dangers. But the street light does not use the alternating current, uses the accumulator to absorb the solar energy, transforms the low voltage direct current into the light energy, does not have the security hidden danger.
4, household photovoltaic power plants
The roof of the farmers use their own idle resources, you can build a domestic photovoltaic power plant installed capacity ranging from three thousand watts, more than ten kilowatts, 20 kilowatts, to save electricity, and can also get state subsidies, electricity can not use up the return back to the grid, stable and reliable, clean energy utilization state are recognized and popularized, and even become a main application model of photovoltaic poverty alleviation.
