The industry analysts believe that the "13th Five-Year Plan" is an important period for the development of the photovoltaic industry, and it is estimated that the annual installed capacity will reach 20 million kilowatts. In this period, we must first vigorously develop distributed photovoltaic applications. Secondly, we must rely on the leader plan to bring market to advanced enterprises and technologies. The third is to vigorously develop photovoltaic poverty alleviation. Finally, we must accelerate technological progress and industrial upgrading. Especially since entering 2016, due to the downward adjustment of the “6.30†subsidy policy, PV development is entering the “small†era, because distributed photovoltaic power generation, especially rooftop photovoltaic power generation, can take advantage of the advantages and characteristics of photovoltaic power generation because it is not currently Due to the limitation of scale, there is no impact of power cuts, and the amount of subsidies is relatively high, and the issuance of subsidies is relatively timely. Therefore, rooftop distributed photovoltaic power generation has received more and more attention from the industry. Li Wenhua, president of Leye Photovoltaic Technology Co., Ltd., said that in 2013, China launched the standard tariff policy for photovoltaic Internet access and distributed subsidy policy, and China's PV market grew to become the world's largest PV market. In 2015, the domestic installed capacity of new PV reached 17.6GW, accounting for more than 30% of the global market. In domestic PV installations, mainly concentrated on ground-based power plants, distributed PV accounts for a relatively low proportion. According to domestic energy statistics, as of the end of the first quarter of 2016, the cumulative installed capacity of distributed PV in the country was 7GW, far lower than 43.3GW centralized ground power station. However, in the photovoltaic utilization, the “13th Five-Year†development plan, the distributed installed capacity will reach 70GW in 2020, which means that within a few years, the distributed annual installed capacity will reach at least 12.6GW, and the development of distributed PV is justified. Time. Li Wenxue also pointed out that the characteristics of distributed photovoltaic and solar energy dispersion are very well matched, on-site collection, local consumption, to achieve a good balance between supply and consumption. Li Wenxuan also cites that Germany is the first country to promote photovoltaic applications. Nearly 50% of the power grids use renewable energy during peak periods, most of which use distributed photovoltaic power generation. The distribution is promising, especially for rooftop PV. Wang Junjuan, chairman of the Guangdong Photovoltaic Industry Alliance and chairman of the Shenzhen Solar Energy Society, believes that rooftop photovoltaic power generation faces the industrial and commercial roof of thousands of households, facing the roof for reinforcement, is a static power generation technology, and the cost of subsequent operation and maintenance. It is relatively low, easy to standardize and green development, and has a good development prospect. However, Wang Junjuan also pointed out that there are still many problems in the development of rooftop distributed photovoltaic power generation. She believes that the primary problem stems from the roof resources, the roof resources should be well structured, the property rights are clear, and it is difficult for 25 years. Second, the state does not subsidize or state subsidies are not in place. The country's PV subsidies, especially distributed subsidies, are not in place. Although there is some easing now, the lag is still serious. Thirdly, the capital issue is difficult to solve. After the introduction of the national PV policy, financial institutions have also introduced a series of financial support, but there are few financial projects that do roof-supported PV support, so the support for reforming financial financing is also urgent. Wang Junjuan also believes that the current service of photovoltaic enterprises is not in place and is an important factor restricting distributed photovoltaic power generation. At present, PV is easy to install and easy to use, but once the product has a problem, at present, the service of the enterprise is not in place. Wang Sicheng, a researcher at the Energy Research Institute of the National Development and Reform Commission, also pointed out that distributed is a relatively complicated one. Unlike large power plants, large power plants have only one business model. Distributed is very complicated. First, you must choose your own business model. , communicate with the grid. Wang Sicheng also believes that distributed photovoltaic power generation is currently developing slowly, from many factors. First, the natural conditions are very poor, followed by construction problems. Because 60% of the building land in our country is residential, it is said that the construction is difficult to make a very large Obstacles, the risk of this transaction is very large. The other is the risk of installation. Is it a long-term disrepair? Is there a problem with leakage? These problems have also caused difficulties. There is also the proportion of spontaneous use of electricity, you do not have to consider your main installed machine, but also consider the reverse power flow, this is required for large power plants, and there are some installation conditions are also diverse. Again, this is not the same as a large power station. Wang Sicheng also pointed out that for distributed photovoltaic power generation, safety is also a very important factor, and the insulation system should be monitored in real time. To do distribution is to be a craftsman's spirit to do a good job of distribution. "In the future, energy storage may be an indispensable means. It plays a big role in solving the reverse power flow. In order to maximize the benefits of distributed photovoltaics, it is necessary to increase energy storage and save excess electricity during the day. It is very typical for distributed power generation at night." Wang Sicheng also believes.
