With the increasing depletion of traditional energy on the earth, the energy problem remains to be solved.As an inexhaustible new clean energy, solar energy has gradually become the main new energy in the future.

Solar photovoltaic is widely used in large power plants and home distribution. So what is photovoltaic distribution? The so-called distributed photovoltaic system, refers to the small-scale photovoltaic power generation system installed in the household or industrial and commercial buildings roof and courtyard, to the owner of "spontaneous self-use, surplus electricity grid" mode of operation. Germany, Japan and other developed countries are mainly distributed photovoltaic, using the "spontaneous self-use, surplus electricity grid" way to solve the problem of photovoltaic power generation, but also to avoid large-scale ground power stations "optical limit" phenomenon.

A considerable proportion of our components are exported to Japan. The client of long-term strategic cooperation is Hansen.

Overseas, 20% of Australian households have installed PV systems, 50% in Germany and 80% in Japan.In China, although there are 200 million independent houses and 5 million villas, only less than 1% of the PV power generation system is installed. The utilization rate of new energy is still very low. There is still much room for PV power generation in the domestic market.The top three of the global installed capacity of photovoltaic power generation are Germany, China and Japan.

Comparison of government subsidy methods at home and abroad

Germany: encourage voluntary use.In Germany's 2013 policy, photovoltaic power generation systems below 500 kW can adopt the policy of "spontaneous self-use, surplus power to the grid"; systems larger than 500 kW can implement the policy of "grid tariff".2MW or above will not be subsidized.Distributed generation (DG) in Germany has experienced an explosive growth in 2008-10 years. In 13 years, DG installed in Germany accounted for 75% of PV generation.

Japan: Japan's rapid development of photovoltaic power generation is due to its high tariff subsidy policy, the price of residential subsidies to the grid as high as 42 yen, equivalent to 2.57 yuan. Japan's high subsidies for new energy are mainly due to the Fukushima nuclear power crisis in 2011, so the Japanese people and government are particularly in need of new energy, the 2020 Summer Olympics and other major events have also promoted the development of solar energy in Japan.However, in recent years, Japan has gradually reduced the subsidy tariff.

The United States: As a developed country, the U.S. government's support for solar power as long as it is still in the bad investment environment, including investment tax returns, accelerated depreciation, direct investment subsidies and other preferential policies.

China: In 13 years, China promulgated the Notice of the State Development and Reform Commission on the Promotion of the Healthy Development of the Photovoltaic Industry by Playing a Price Leverage Role, which clearly stipulated that the annual subsidies for photovoltaic power generation should be 0.42 yuan per kilowatt-hour, unchanged in principle for 20 years.The price of electricity for three types of photovoltaic power generation areas is also specified.

However, the market share of distributed photovoltaic power generation in China is quite different from that in other countries.The proportion of distributed PV installed in China is far below that of foreign countries.

Different countries have different national conditions, and the proportion of distributed photovoltaic generation is different.For China, the market needs to be distributed rapidly, and distributed really has a lot of market development space.Next is the choice of users.
