Mobile WebSiteDistributed photovoltaic power generation refers to the location of the user or near the construction and operation to the user side of the spontaneous use of self, with excess power online and in the distribution system balance characteristics of the photovoltaic power generation facilities. The state has been actively encouraged by the distributed photovoltaic power generation system, and introduced a series of support measures. In particular, the end of the introduction of the "power development" thirteen five "planning" on the distributed photovoltaic set extraordinary goals: "2020, solar power installed capacity of 110 million kilowatts or more, distributed photovoltaic 60 million kilowatts or more." There are indications that distributed PV, especially home distributed photovoltaic, is about to usher in a period of rapid development.
First, the development of distributed photovoltaic speed, but the gap with the developed countries is still large
Over the years, the state to reduce Europe and the United States on China's PV double reverse policy on the impact of enterprises, the state introduced a series of policies for domestic photovoltaic power plant construction. Although this policy effectively solve the problem of excess capacity of PV modules, but it led to the extraordinary development of China's solar power plants, and the development of distributed photovoltaic slow, the proportion of serious imbalance.
At the same time, compared with developed countries, the proportion of China's distributed photovoltaic is seriously low, the proportion of foreign distributed photovoltaic Germany is about 80%, the United States and Japan about 50%. China as of the end of 2016, the cumulative installed capacity of photovoltaic power generation 77.42 million kilowatts, of which the cumulative cumulative installed capacity of 10.32 million kilowatts, accounting for 13.3%. Japan and Europe and the United States developed countries, large-scale power plants and the proportion of home-based PV to maintain a healthy development in the 1: 1, while China's large-scale photovoltaic power plant accounted for up to 80%. As large-scale power plants are mostly built in the remote areas of the northwest, simply can not really solve the residents of electricity, and because of grid construction lag, resulting in the phenomenon of abandoned light frequently, serious waste of resources.
Second, the future rapid development of distributed photovoltaic can be expected, the policy is the biggest driving force
At present, the relevant national energy planning on the distributed photovoltaic has made extraordinary development goals. "Power development" thirteen five "plan" proposed to "2020, solar power installed capacity of 110 million kilowatts or more, distributed photovoltaic 60 million kilowatts or more." From the scale of distributed PV installed capacity, the new installed capacity of 4.24GW in 2016, an increase of 200%, the cumulative installed capacity of 10.32GW, from 2020 planning targets and 50GW space, the next four years, an average of at least 12GW new installed capacity, with Huge development space. To ensure the realization of the objectives, the state introduced a series of policies to be supported, the most typical is the price policy support.
At the end of 2016, the National Development and Reform Commission issued "on the adjustment of photovoltaic power generation onshore benchmarking price of electricity," the proposed sub-resource area to reduce the photovoltaic power plant, onshore wind power benchmarking price, and distributed photovoltaic power subsidies and offshore wind Adjustment. After January 1, 2017, the benchmark price of the new PV power plant in the first class to the three types of resource areas was adjusted to 0.65 yuan per kilowatt-hour, 0.75 yuan and 0.85 yuan respectively, down 0.15 yuan per kilowatt-hour price of 2016 yuan , 0.13 yuan. National Development and Reform Commission at the same time clear that the future price of PV benchmark price changes according to the cost of adjustment once a year. Relative to the ground centralized power plant subsidies down, distributed photovoltaic projects are still strong, to maintain 0.42 yuan per kilowatt electricity price, profit is relatively rich, as the rapid development of distributed photovoltaic to promote the biggest positive factors.
In addition to price support, the central government departments have also introduced a series of policies to support the distributed photovoltaic. February 27, 2013, the State Grid held a press conference to the community, "on the distributed power supply and network service work advice" to solve the problem of distributed photovoltaic grid difficult. In January 2014, the National Energy Board issued the Notice of the National Energy Administration on Releasing Newly Built Scale for PV Generation in 2014 to determine the scale of new PV construction in 2014. The total scale of the new record is 14GW, 8GW. On September 4 of the same year, the National Energy Board promulgated the Circular on Further Implementing the Policies on the Implementation of Distributed Photovoltaic Power. To promote the development of distributed PV, the policy made significant adjustments to its connotation and denotation: Electric Internet "or" full Internet "in a model.
In 2014, dozens of policies issued around the country on the promotion of distributed photovoltaic, both Jiaxing Xiuzhou eye-catching 2.8 yuan subsidy price, and Jiangxi to the mainstream of distributed photovoltaic high-profile debut. In 2014, the National Energy Board introduced about 13 of the PV industry policy, which clearly on the distributed photovoltaic up to 5.
Third, the domestic distributed PV market space is huge
From the experience of developed countries, the PV industry has its own development characteristics, the trend is generally from the concentration to the distributed development, which is determined by the characteristics of photovoltaic.
At present, China's PV market, there are electricity tariff cut, abandoned light limit, renewable energy subsidies in 2017 is expected to exceed 60 billion yuan and other issues, and these problems with the development of ground power plants continue to accompany the short term these problems are difficult to solve The At the same time, the ground power station is mainly driven by the leader plan, its installed capacity has been relatively limited. The distributed PV is suitable for installation in industrial parks, economic development zones, large industrial and mining enterprises and shopping malls school hospitals and other public buildings roof, the advantage is close to the user side, low cost. In addition, the roof made photovoltaic can play a role in insulation, both power, but also electricity, serve two purposes. It is estimated that China's distributed PV market with a future capacity of 6 trillion power carrying capacity. In a series of factors under the birth of the future more new installed capacity will rely on distributed photovoltaic to achieve.
In addition, the electricity to change in the placement of the electricity side of the advance, especially the gradual establishment of electricity market transactions, will also push up the construction of distributed photovoltaic project demand is expected to push the energy department for many years of distributed photovoltaic will start from 2017 Rapid growth.
For a long time, the rapid growth of the scale of the western new energy power station and the lack of cross-regional transmission capacity is a significant contradiction. For the photovoltaic power station, the Energy Bureau early and clear development priorities, limit the amount of power stations in the west, to guide the industry to distributed. At the same time, distributed power generation close to the electricity load, and in line with intelligent distribution, power development direction, the future will become an important direction for the development of domestic photovoltaic.
"Thirteen five" there is a very important idea is that the development of renewable energy more attention to the use of near consumption, the nearest use of distributed photovoltaic fully in line with this principle is the future direction of development. Compared to large power plants, distributed to solve the long-distance transmission of large power plants and grid pressure. At present, with the promulgation of national electricity reform policy and the development of energy Internet, China has more and more companies from the power consumption side of the business model, to enable the power supply side of the Internet, is expected to achieve energy demand side management and energy Internet real Landing. With the development of technology, energy Internet landing, distributed weaknesses such as business model is unclear, electricity collection difficulties will be resolved.
Fourth, the distributed high rate of return on investment, highlighting the investment value
At present, the state strongly encourages the distributed PV application form, the implementation of distributed photovoltaic projects is the "basic price + subsidy" price policy. Among them, the state-level subsidies 0.42 yuan / kWh; many powerful provinces, cities and counties, on the basis of the state subsidies and the introduction of local subsidies.
Shanghai 5kWp solar system, for example, with an annual output of 6000 degrees, 30% for their own, 0.977 yuan third ladder price, the proceeds include three parts: First, the state and local full subsidies, the national subsidy of 0.42 yuan per degree, Shanghai The annual savings of 49 yuan; the second is to save their own electricity, 5kW system can save 1758 yuan per year; third is to send the national grid sales power, 5kW system can sell 1830 yuan a year. All calculated down, the annual income of about 8500 yuan, while the 5kW system investment of about 50,000 yuan, the static return on investment as high as 17%.
Over the next few years, with the national and local solutions to the problem of distributed photovoltaic dilemma introduced, the gradual implementation of tax incentives, distributed PV project revenue is expected to further improve. The market volume of mature distributed photovoltaic has led to a variety of enterprises, capital influx. Only in the first quarter of 2017, "grab roof" war will be carried out in full swing.
Fifth, the family of distributed photovoltaic may usher in explosive growth
As the closest living from the people of the distributed photovoltaic, because of its quick, small investment, and simple network, the advantages of timely subsidies, is currently the most development potential of the field.
The first is quick. Home photovoltaic power plant is the fastest application process, the fastest installation, the fastest network, get the fastest application of subsidies. Access to the power company can know that usually the family power plant only 10 working days, you can get access to the views of the application. The entire installation process is usually not more than 3 days, and network acceptance generally does not exceed 7 days, the general payment is not more than 3 months a cycle. Therefore, the entire process can be completed up to 15 days.
Followed by small investment. In China, the general urban villa household electricity consumption is large, but China's villas are mostly European roofs, roof facing more, so the installation capacity of most of the 5-8kWp between the individual villas or high roof, you can install 10kWp ; And 5-8kWp solar energy system investment, only only 6-10 million. Although the general rural villa larger roof, but China's subsidy for self-use superfluous Internet, the general electricity consumption will not be too much, therefore, the rural roof installation capacity is generally 3-5kWp. This, put in 3-5 million, rural areas can enjoy the solar system.
Again, the grid is simple. Grid-connected process as long as the certificate issued to ensure that there are grid installed meter, you can apply for free distributed photovoltaic power generation access. At the same time, the power company free of charge to provide two meters, free access design. Installation does not require special access equipment, and network switch, in line with national requirements of the components, the inverter can be.
Finally, the subsidy is timely. At present, the distribution of distributed household power plants is the fastest of all new energy projects. Large-scale power plants are delayed to pay subsidies for up to 24 months. This has seriously affected the enthusiasm and market of investing in solar energy and greatly raised the risk of investment enterprises increase. The family project, usually 3 months to implement once, the longest no more than 6 months. This allows all solar roof customers to see the benefits, believe that the return on investment in solar energy.
