    The use of solar energy is mainly divided into the following aspects: household small solar power stations, large grid-connected power stations, building integrated photovoltaic glass curtain walls, solar street lights, wind and solar hybrid street lights, wind and solar hybrid power supply systems, etc. The main application methods are building integration and wind and solar power systems. Complementary system. Advantage 1. Solar energy is inexhaustible and inexhaustible. The solar radiation energy received on the earth's surface can meet 10,000 times the global energy demand. As long as solar photovoltaic systems are installed on 4% of the world’s deserts, the electricity generated can meet global needs. Solar power generation is safe and reliable, and will not suffer the impact of energy crisis or unstable fuel market; 2. Solar energy can be everywhere, and power can be supplied nearby without long-distance transmission, which avoids the loss of long-distance power transmission lines; 3. Solar energy does not use fuel, and the operating cost is very low; 4. Solar power generation has no moving parts, is not easy to use and damage, and is simple to maintain. It is especially suitable for unattended use; 5. Solar power generation does not produce any waste, has no pollution, noise and other public hazards, and has no adverse effects on the environment. It is an ideal clean energy; 6. The solar power generation system has a short construction period, is convenient and flexible, and can add or reduce the amount of solar power arbitrarily according to the increase or decrease of the load to avoid waste. We are committed to the design and production of complete solar photovoltaic power generation system equipment, focusing on household solar power generation systems. Widely used in industrial and commercial rooftops, residential rooftop photovoltaic power generation, photovoltaic agriculture and animal husbandry power generation, remote areas photovoltaic off-grid power generation systems and small solar generators, solar energy application products R & D, production, sales, installation, and service as a professional company. Reliable products, efficient services, and more professional solutions.

    Although solar power generation is affected by day, night, rain, and seasons, it can be carried out in a distributed manner. Therefore, it is suitable for each household to generate electricity separately, and it must be connected to the power supply network so that each household can sell it when the electricity is abundant. The power company can buy from the power company when it is insufficient. The technology to achieve this is not difficult to solve, the key is to have corresponding legal protection. Developed countries such as the United States and Japan have enacted corresponding laws to ensure the benefits of households that use solar power and encourage households to use solar power. Japan has realized the interconnection of the solar power system with the power grid of the power company in April 1992, and some households have begun to install solar power equipment. The Ministry of International Trade and Industry of Japan has implemented a system of subsidizing two-thirds of the cost of purchasing solar power generation equipment for personal homes in 1994. It is required that 1,000 households in the first year and 70,000 households in 2000 are equipped with solar power equipment. According to estimates by Japanese authorities, if 80% of Japan’s 21 million individual homes are equipped with solar power generation equipment, 14% of the country’s total electricity needs can be met. If solar power is also used in factories and office buildings, solar power generation Will account for 30%-40% of the national electricity. The most important factor hindering the popularization of solar power generation is the high cost. In order to meet the electricity needs of ordinary households, the 3 kilowatt power generation system requires 6 to 7 million yen, not including the installation wages. Relevant experts believe that solar power can be truly popular when it is reduced to at least 1 million to 2 million yen. The key to reducing costs is that solar cells improve conversion efficiency and reduce costs. Not long ago, Texas Instruments and SCE announced that they have developed a new solar cell. Each unit is a small bead less than 1 mm in diameter. They are densely and regularly distributed on soft aluminum foil, just like many silkworms. The egg is close to the paper. There are 1,700 such units distributed over an area of approximately 50 square centimeters. The characteristic of this new battery is that although the conversion efficiency is only 8%-10%, the price is cheap. Moreover, the aluminum foil backing is soft and strong, can be folded freely like cloth and durable, and can generate electricity when hung in the sun, which is very convenient. It is said that using this new solar cell, the equipment with a power generation capacity of 1.5 to 2 US dollars per watt, and the cost of each kilowatt-hour of electricity can also be reduced to about 14 cents, which can completely compete with the electricity generated by ordinary power plants. Every f...

    Advantages of solar photovoltaic power generation 1. The solar energy will not produce pollution that endangers the environment during the conversion process. 2. Solar energy resources are spread all over the world and can be exploited in scattered and regional areas. About two-thirds of our country can make better use of solar energy resources. 3. Photovoltaic power generation is intermittent. It only generates electricity when there is sunlight, and the power generation is directly proportional to the strength of the sunlight. 4. Photovoltaic power generation is static operation, no moving parts, long life, no or very little maintenance. 5. Photovoltaic systems are modularized and can be installed in places close to power consumption. In areas far away from the grid, it can reduce transmission and distribution costs and increase the reliability of power supply facilities. Solar power generation is mainly divided into two systems: on-grid and off-grid power generation. The on-grid power generation system is the direct current generated by solar modules is converted into AC power that meets the requirements of the mains grid through a on-grid inverter and then directly connected to the public grid. Due to the advantages of small investment, fast construction, small footprint, and large policy support, it is the mainstream of on-grid power generation at present. Off-grid solar power generation systems are systems that exist independently of the power grid. It is widely used in remote mountain areas, areas without electricity, islands, communication base stations and other applications.
