Photovoltaic has broad prospects in the countryside, but there are still problems.
in the bleak winter, where is the way out for China's photovoltaic products, which have been hit by the "double anti" of Europe and the United States? The recent introduction of many new policies shows that the relevant government departments have realized that only by opening up the domestic terminal market can China's photovoltaic industry bring vitality to the bottom
since May this year, the Ministry of industry and information technology has conducted intensive research on the application of solar photovoltaic in rural areas across the country, and has recently announced that it will take the lead in organizing and implementing a "photovoltaic to the countryside" plan. On December 19, at the executive meeting on photovoltaic industry, the State Council also proposed for the first time to "encourage households to install and use photovoltaic power generation systems", which means that the door of distributed photovoltaic power generation applications may soon be opened to the rural market
Wen Jianhua, chief operating officer of Hunan Gongchuang Photovoltaic Technology Co., Ltd., said, "we have been looking forward to the policy of photovoltaic going to the countryside for a long time, which is the only way for solar energy to truly benefit the people."
at present, photovoltaic power generation in rural areas of China is almost a "vacuum zone", and it is very important for China's photovoltaic products to develop this potential terminal market
Li Junhua, a researcher of China business intelligence industry, told China Science Daily that from the perspective of resource advantages, technological level, production capacity and industrial foundation, China has the conditions and foundation to accelerate the start of the photovoltaic market, and the rural market, which urgently needs the production and living electricity and has rich land resources, will become a new growth point of photovoltaic domestic demand
for example, the inclined surface of agricultural plastic greenhouse can be used to install solar cell modules, and a new greenhouse composed of transparent photovoltaic glass can be built, which can not only generate electricity while planting vegetables, but also use photovoltaic cell technology to promote the photosynthesis of plants in the greenhouse
it is reported that the standardized agricultural greenhouse area in China has reached 50million mu. If the photovoltaic integrated system is fully completed, it will drive a huge market of 250billion yuan
Wen Jianhua further pointed out: "in fact, as far as agricultural production is concerned, the greenhouse we know best is only a typical application, not all."
he said that due to the vast area of rural areas in China, there are many places where electricity is used in the fields. It is unrealistic to use all electricity access, and photovoltaic power generation can make up for corners that cannot be covered by electricity. For example, a kind of insect killing lamp used in field pest control can be powered by small thin-film solar cells. In addition, photovoltaic products can also be used in water supply and irrigation systems
compared with production applications, photovoltaic is more widely used in daily life. Wen Jianhua said that the photovoltaic building integration currently being promoted by the country is not only suitable for cities, but also suitable for rural areas. He once made a detailed survey in rural areas in the South and found that in some richer areas, several families often live in the same building, and the household electricity consumption is even higher than that of urban residents
"I have been to a farmer's house, which has a total of three floors and more than a dozen rooms. Excluding the balcony, the total area is nearly 400 square meters. The whole family uses electricity for cooking and baking, and the monthly electricity charge is as high as more than 1000 degrees. Such a family is very suitable for transforming into a photovoltaic integrated building." Wen Jianhua said
is not a "roadblock"
however, PV to the countryside is not everywhere a broad road surrounded by flowers. It can be predicted that in the future, photovoltaic power generation equipment built by a considerable number of farmers will not be fully used for their own use, and the surplus electricity outside production and life will be incorporated into local electricity in exchange for economic benefits, and the merger problem will become the biggest "stumbling block"
Li Junhua said that the excess electricity was incorporated into the local rural electricity 9 Input voltage: when exchanging 10% of 380V, it involves approval and technical obstacles, which is indeed a thorny problem that needs to be solved urgently when photovoltaic goes to the countryside
it is understood that in order to accelerate the promotion of distributed photovoltaic, State Grid Corporation of China has issued the "notice on doing a good job in distributed photovoltaic power generation and service" (hereinafter referred to as the "notice") at the end of October this year. The notice requires that if the total installed capacity of a single point of consolidation does not exceed 6 MW, the public power transformation costs caused by the time of consolidation shall be borne by the power enterprise, and the costs of the access system engineering shall be borne by the power enterprise and the owner respectively depending on the combination and non combination. However, if not only do they have to sell electricity, owners need to be equipped with more two-way smart meters
since the issuance of the notice, 521 distributed photovoltaic power generation and related consulting businesses have been accepted nationwide in November this year, 123 installation applications have been accepted, and the total installed capacity has reached 176.4 MW
on December 21, a distributed photovoltaic power supply in jialinggou community of Qingdao was successfully incorporated into Qingdao power, marking the official merger of the first distributed photovoltaic power supply for residential users in China
it can be seen that the country has taken a substantial step in promoting distributed photovoltaic power generation, which will gradually clear the policy obstacles for the future of photovoltaic to the countryside
Wen Jianhua believes that when the government promotes photovoltaic to the countryside recently, the ideal situation is still spontaneous self-use, that is, distributed, separated, or first adopt nearby integration, but only use (electricity). In the future, when it is slowly developed and sold, it can be household units or village and town units
he frankly said that there is a certain gap between the conditions of rural areas and cities. It is only a township in many places that determines to a large extent that the use of this kind of plastic and rubber has a substation. The distance between the farmer's residence and the substation is too far, which also causes some difficulties. "But with the new rural construction and urbanization process, I believe these difficulties will be gradually solved."
there is an urgent need for subsidies and supporting facilities
at present, a considerable number of views in the industry believe that rural families may not be able to bear the cost of thousands of yuan to build simple household photovoltaic power stations, which will seriously hinder the promotion of photovoltaic in the countryside
however, a recent survey conducted by Hunan Gongchuang Photovoltaic Technology Co., Ltd. in rural Hunan shows that according to the current construction cost and level, if it is invested by users themselves - even if the state has no special subsidies for construction and transformation, only the industry has issued a power generation subsidy standard of 1 yuan/kWh. Whether it is not, it can recover the capital within 6 to 8 years, with a yield of about 12% to 15%
Wen Jianhua said: "the survey results will help improve the enthusiasm of rural families to participate."
he said that even if rural users have no money to invest, they can entrust energy contract management companies to invest and manage in advance. They only need to hand over the income from the later generation to the latter, and only use part of the electricity to maintain production and life
Li Junhua suggested that in the early stage when farmers do not understand the return income, the government can adopt the promotion method of direct investment and subsidies to enterprises. "Some rural photovoltaic power stations can be directly invested and constructed by the government or shared, and the local or users are responsible for the management and operation, but the government investment will be large, or enterprises can be encouraged to invest and construct, and the government will give enterprises reasonable subsidies."
however, he reminded that no matter which way, it is difficult for China to promote and implement on a large scale in a short time
in addition, if the resolution of the national power value can almost reach 1 in 100000, the photovoltaic power will be purchased to the countryside at the price of 1 yuan/kWh set by the development and Reform Commission, while the current sales price of the national power is generally about 0.5~0.6 yuan per kWh. How the government subsidizes the loss acquisition of the national power will become another key to the success or failure of the plan
Li Junhua also pointed out that due to the absence of supporting subsidies and relevant supporting policies for photovoltaic to the countryside, enterprises lack clear investment return expectations in this field
the latest good news is that the highly concerned distributed generation subsidy policy was finally confirmed at the executive meeting of the State Council on December 19. The market predicts that the subsidy standard to be introduced is 0.4~0.6 yuan/kWh. Guifangxiao, an industry analyst at Great Wall Securities, believes that this standard has investment attraction
"the introduction of photovoltaic to the countryside should take the lead in areas with relatively good lighting resources and relatively easy building reconstruction. At the same time, the state should make overall planning and joint promotion from the aspects of building specifications and subsidy policies, and introduce more detailed operating methods in project application, docking and qualification approval."
