Analysis Of PV Development Prospects In 2018 And How Will Solar PV Develop In The Future
- Jun 06, 2018 -


The traditional fuel energy is decreasing day by day, and the harm to the environment is becoming more and more serious. At the same time, 2 billion people still can not get the normal energy supply. At this time, the world has focused its eyes on renewable energy, hoping that renewable energy can change the energy structure of human beings and maintain long-term sustainable development. Solar energy has become the focus of attention because of its unique advantages. Abundant solar radiation is an important source of energy. It is an inexhaustible, pollution-free, cheap, and free energy source for human beings. Solar energy reaches 800 thousand kilowatts per second to the ground. If the solar energy of 0.1% of the earth's surface is converted to electrical energy, the conversion rate is 5%, the annual power generation capacity can reach 5.6 * 1012 kilowatt hours, equivalent to 40 times the energy consumption in the world.


Solar energy resources are abundant and widely distributed. It is the most potential renewable energy in twenty-first Century. With the increasingly prominent global energy shortage and environmental pollution, solar photovoltaic power generation has become a new industry in the world because of its clean, safe, convenient and efficient characteristics. Against this background, the global photovoltaic industry is growing rapidly, and the scale of industry continues to expand, and the cost of products continues to decline. China's photovoltaic power industry has also developed rapidly, and has become a few industries in China, which can participate in international competition synchronously, and can reach the international leading level.


In recent years, the installed capacity of photovoltaic power generation in China has been the first in the world for 5 consecutive years, and the total installed capacity has ranked 3 in the world for the first time in a row. Photovoltaic technology is constantly innovating and breaking through, leading the world, and has formed a complete photovoltaic industry chain with international competitiveness. Many investors are very interested in the analysis of the development prospects of solar photovoltaic in 2018. How will solar PV develop in the future?

National Energy Strategy: under the background of national non renewable resources and energy security, distributed new energy has become a very important part of the national energy strategy. It is one of the effective ways to alleviate the serious shortage of electricity in China and ensure the sustainable development strategy, and has great potential for development. As one of the new distributed energy sources, photovoltaic power, to a certain extent, reduces the coal and other pollution caused by coal, such as coal fired boilers in factories and families.


Environmental pollution needs: speaking of environmental pollution, the first to bear the brunt is air pollution, how to reduce air pollution, mainly in two aspects. On the one hand, industry reduces the use of pollution like energy, such as prohibiting the burning of straw, such as reducing coal use, on the other hand, strengthening the use of new energy generation, thus solar photovoltaic is particularly important. It's important.


Market needs: in the face of China's large 1 billion 300 million population base, whether in cities, towns or in rural areas, whether factories or residents, electricity is the necessary product for people's life. For the installers, the use of "spontaneous self use, allowance for Internet" can reduce the cost of electricity, at the same time Surplus electricity can also create revenue, the so-called "one stone", for dealers, the state's preferential policies, strong support, according to the development and reform department, the national photovoltaic project price policy has been introduced in 2018, the "spontaneous self use, allowance for the Internet" model of distributed photovoltaic power project countries still give priority to support . Solar photovoltaic has become a direct industry, of course, it will be in full swing. In the next 3 years, there will be 200-300 million households to install photovoltaic power stations, which is a huge market space. According to the statistics of the latest National Bureau of statistics, solar power increased by 46.8% in December 2017. Lei Jun, the founder of the millet mobile phone, once said, "standing on the tuyere, even the pigs can fly." At present, we are standing on the high speed development of solar PV. We should consider how we can fly higher and farther.

Photovoltaic energy storage and storage need to be protected. Photovoltaic power storage mode is expected to be promoted.


In October 11, 2017, the national development and Reform Commission, the Ministry of finance, the Ministry of science and technology, the Ministry of technology, the Ministry of industry and the Energy Bureau, and the Energy Bureau jointly issued the first industry policy of the energy storage field, "guidance on promoting the development of energy storage technology and industry in China", clearly proposed to promote energy storage and upgrade the utilization of renewable energy, and encourage the rational distribution of renewable energy stations. The storage energy system is set up to promote the coordinated operation of the energy storage system and the renewable energy, and to establish the compensation mechanism for the side energy storage of the renewable energy field station, and to support a variety of energy storage to promote the renewable energy dissipation.


If the energy storage system is applied to the photovoltaic power generation, it can provide a certain buffer for the power grid connected to the photovoltaic power station, and play the role of smoothing and energy scheduling, thus improving the power quality, improving the predictability of the new energy generation, and improving the utilization rate. To a large extent, the problem of "volatility" can be solved.


According to the latest photovoltaic subsidy policy, the distributed photovoltaic power generation project, which adopted "spontaneous self use and surplus net" mode after 2018, is 0.37 yuan per kilowatt hour (including tax), down 0.05 yuan from the previous year. In order to achieve the PV parity, the gradual withdrawal of state subsidies will be an inevitable trend, and the future user revenue will become more and more dependent on the utility price gains. Due to the time lag between the peak period of photovoltaic power generation and the peak period of user power consumption, the current utilization rate of users is relatively low, and some of them are less than 30%. If the energy storage system is introduced, energy storage during the peak period of photovoltaic power generation and power consumption at peak hours during the night will enhance the utilization rate of PV and increase user returns. With the decrease of energy storage cost, it is expected that energy storage in the field of distributed photovoltaic will steadily increase in the future.


Solar photovoltaic power generation will occupy an important seat in the world's energy consumption in the near future, not only to replace some conventional energy, but also to be the main body of the world's energy supply. It is expected that by 2030, renewable energy will account for more than 30% of the total energy structure, and solar photovoltaic power generation will account for more than 10% of the total power supply in the world. By 2040, renewable energy will account for more than 50% of the total energy consumption, and solar photovoltaic power will account for more than 20% of the total power. By the end of twenty-first Century, renewable energy will be renewable. In the energy structure will account for more than 80%, solar power will account for more than 60%. These figures are enough to show the development prospect of solar photovoltaic industry and its important strategic position in the field of energy.
