China's growth of distributed solar photovoltaic power generation and challenges

Since 2010, the global solar photovoltaic power generation booming development, annual growth rate of 40%. China as a leader of solar photovoltaic (pv), by 2017, the solar photovoltaic capacity has up to 130 GW, among them, the growth speed of distributed photovoltaic significantly faster than large solar power plants. On August 29, 2018, a new energy distributed in China are reviewed the development status of solar photovoltaic power generation, analysis the reason of the rapid growth of China's distributed solar photovoltaic power generation, and looking forward to the new policy situation, China distributed solar photovoltaic power generation will face the challenges and opportunities.

　　1. The current situation of the development of distributed photovoltaic

at present, the major distributed solar photovoltaic power generation device installed in China's economy the most prosperous east and south, about 52% of the capacity from zhejiang, shandong, jiangsu and anhui four provinces. In 2017, China is about 19 distributed solar photovoltaic power generation capacity. 4 GW, 3 higher than in 2016. 6 times, solar photovoltaic power generation in China in the total installed capacity of 27. 1%, 13. 7 TWh of electricity, enough to all families in Beijing power supply 7. Five months.

national goals

in 2016 issued by the China's solar energy development & other; Much starker choices-and graver consequences-in & throughout; Planning, distributed solar photovoltaic capacity should be rising at an annual rate of 100000 kilowatts, in 2020, at least 600000 kw. At the same time, to build 100 distributed solar photovoltaic demonstration area, 80% of the new building roof and 50% of existing buildings equipped with distributed solar photovoltaic system. In addition, in 2014, China launched a solar pv plan for poverty alleviation, support the development of distributed solar photovoltaic, and allows families free use electricity or sell it to the grid.

incentives

to achieve national goals, since 2013, China introduced a series of incentives in the development of solar photovoltaic (pv) policy. One of the most influential is subsidies distributed solar photovoltaic system. In addition to the national solar subsidies ( 0. 32 yuan/kW· h） , 10 provincial, 36 regional and 10 at the county level and is introducing local subsidies. Durability of photovoltaic solar power systems and related incentive policy makes the distributed solar photovoltaic power generation has become one of the most attractive investment projects.

down cost and improve efficiency

2010 & ndash; In 2017, the global solar photovoltaic components fell by an average of 79%, at the same time, technological progress significantly improve the efficiency of solar photovoltaic power generation. Influenced by these factors, in 2017 China solar power average cost is about 0. 5 yuan/kW· H, was 75% lower than in 2010. A sustained drop in cost to further improve the distributed solar photovoltaic projects to attract private companies.

profitable business models

China's commercial and industrial electricity price is much higher than family. Therefore, the enterprise more distributed solar photovoltaic power generation device installed, to self-sufficient in power and cost savings. In addition, combined with agriculture, fisheries, animal husbandry, & other; Solar photovoltaic (pv) + & throughout; Is showing the potential of solar photovoltaic power generation more in the future. China distributed solar photovoltaic power generation will face the challenge and opportunity

challenge

at present, the distributed solar photovoltaic power generation pilot project provides developers with three possible choices: (1) to select an existing local subsidies. However, these subsidies may be due in the coming years. (2) wait for next year's national subsidies, quotas ( Has yet to be announced) 。 (3) without subsidies development projects.

despite China's solar energy policy has been a huge success, but in the current new policy situation, distributed solar photovoltaic projects will continue to prosper there is great uncertainty. Opportunity for

distributed photovoltaic solar pilot project may be in the challenge to create opportunities for developers. China's National Energy Administration ( 国家能源局,NEA) Launched the distributed generation of point-to-point trading pilot program, it is a win-win for power producers and consumers. The pilot put forward three patterns: (1) direct selling. Electricity generators to sell directly to consumers distribution, and to pay charges for electricity transmission grid companies. (2) commissioned sales. Power grid company representative generator sell distribution power to consumers. (3) grid sales. Generator according to the local large-scale solar power plants of feed-in tariffs to sell electricity grid company. If can win power grid company's investment, therefore, the sustainable growth of distributed solar photovoltaic (pv) in the future will be secure.
