Introduction: In most parts of China, diesel was used to generate electricity, and the cost remained high. Since the last century, people have begun to study solar photovoltaic power, until 2019, solar floodlights and so on have become popular. In Shenzhen, you can see many street lights. The lights in front of the store are all outdoor solar lights. Solar energy conservation and environmental protection, people can not help but care about the history of solar energy development.

    The technical development of China's domestic solar photovoltaic power system began in the 1970s, and in the early 1980s, enterprises began to produce in small quantities, but because the cost of photovoltaic power generation was very high, it stayed for the next ten years. In the stage of scientific research and demonstration. Photovoltaic power generation is likely to become an alternative energy source in the 21st century. However, from the realistic demand of the market, the home solar photovoltaic power system is mainly used for power-free population in areas without electricity or electricity.

    The western regions of China include Tibet, Guizhou, Gansu and Inner Mongolia. Qinghai, Xinjiang and Sichuan are the majority of people without electricity. Most of China's inhabited islands are about 15 to 100 km off the coast, mainly in Zhejiang, Fujian and Guangdong provinces. Some are distributed in Shandong and Liaoning, while the rest are in Hainan, Taiwan, and Guangxi. At present, some islands use diesel to generate electricity. Due to the high diesel transportation cost, the electricity price per kWh is sometimes as high as RMB 3~4.5. Such a high price makes it possible to supply only a few hours of electricity every night. Where diesel can not be used to generate electricity, only candles and kerosene lamps can be used for lighting. Some use batteries. Without electricity or electricity, the local economy is largely restricted.

    On the other hand, these western provinces and coastal islands in China are rich in wind and solar resources, and most of them can fully utilize environmentally friendly and economical renewable energy to solve their electricity problems. Since the 1990s, sales have developed and gradually formed a certain scale under the guidance, support and cultivation of the state and some international cooperation projects.

    By the end of 2005, about 750,000 home solar photovoltaic power systems had entered the user's home. Most of these users were pastoralists in pastoral areas. These households had relatively low power levels, and the average households only reached 20W. Left and right, generally only meet the basic lighting needs. In addition, there are also farmers and beekeepers in forest areas and agricultural areas, as well as small units such as roads, schools, shops, etc. that are not using electricity, and also use household solar photovoltaic power systems, as well as some urban residents in areas with power shortages. Become a user of home solar photovoltaic power systems. If these household solar photovoltaic power systems are kept at 80%, plus the national bright project and the photovoltaic power station that sends electricity to the township project, at least 1 million households in China currently rely on photovoltaic power generation systems to solve basic living lighting power. .

    By the end of 2005, China's photovoltaic power generation market has reached a total installed capacity of 70MW, of which about 43% is for rural power construction, and there are about 3 million households without electricity in the country. It is estimated that at least 1.5 million of them need to be In the next ten years, photovoltaic or wind-solar hybrid power generation systems will be used to solve them. Due to restrictions on living conditions, most of them can only use a decentralized power supply, that is, a home solar photovoltaic (or wind and solar complementary) power system. And many users who have already used PV systems will also upgrade and improve the level of electricity consumption. Therefore, China's PV market potential is still very large.

    Since 2001, domestic solar photovoltaic power systems produced by Chinese companies have been exported to many countries around the world, and the demand in the international market is gradually increasing. According to the survey and research results, in the present and future period, regardless of China or in many developing countries, the demand for rural power construction with the main goal of solving the problem of electrification of people in power-free areas will still be household solar photovoltaic power sources. The main sales market for the system. Due to the urgent and actual market demand, China's domestic solar photovoltaic power system research and development and production promotion work has been at the forefront of the world, and its marketization development is also the highest among the countries in the world.

    The corresponding degree of development of consumer protection mechanisms and market supervision mechanisms is relatively complete. For example, standards, testing, certification and other capacity building work are not falling behind, and have a good international and domestic market development environment. However, it should not be overlooked that in the products sold in the market (including some exaggerated words, pit consumers). It is worth noting that the related technologies and configurations of the home solar photovoltaic power system can be applied to more fields such as street lamps, insecticidal lamps, advertising light boxes, etc. through appropriate deformation or improvement. Also, low-voltage electronic light-emitting diodes (LEDs), as a new light source with many significant advantages and development prospects, have been increasingly used in solar photovoltaic power systems.

    Research on home solar systems has reached a certain level. The market development is also very perfect, but in order to avoid exaggerated products in the market, consumers are better to choose a regular store to buy. Nuusolar provides customers with high quality and economical solar lighting products.
