The structure of the solar power system, with high performance solar cell assemblies, is centralized on the roof and is organized into a solar array. Solar arrays absorb solar light and generate direct current electricity, which is converted by reversers to communication power available for domestic appliances, and the remaining electrical power can be stored in the storage cells. When the batteries are full, the remaining power can be uploaded to the grid and the corresponding price obtained to achieve the target. Hpv has been active in the development and development of advanced film solar technology since its entry into the membrane generation industry, and has continued to buy and sell a number of thin film technology companies overseas, including solibro in germany, mia solé in the united states, global solar energy in the united states and alta davis in the united states; these companies possess globally advanced copper and arsenic (cig) technology, and have advanced equipment and manufacturing capabilities in production lines. In many parts of the world, including the united states, germany, sweden, beijing and sichuan, han pv has a professional and good team of scientists who continue to upgrade the performance of thin film-generated solar technology, enabling us to provide customers with advanced turnkey production line solutions. Hanhua is a new generation of both clean power generation and high-level functionality that can be introduced by han, and which is more in line with modern architectural aesthetic needs. Hanwald has a two-storey adhesive adhesive process for a flexible copper (cigs) film solar chip at the hancan global level, which is sealed in the inner layer of the high-photoscale glass and integrated with the roof of the house. More than 91. 5 per cent of the photometric rate and 17. 5 per cent of the volume conversion rate of chips allow hanwa to convert solar energy to electrical power in a limited way, producing qualified economic benefits, and to meet the architectural integrity and aesthetic design needs, which are the product of the upgrading of the market's existing distributed solar products and traditional roofs. Its large-scale extension would make a positive contribution to the promotion of energy alternatives. The han-pv operation includes the production of upstream thin film equipment and downstream photovoltaic applications, with a focus on the manufacture of integrated and distributed energy-voltaic power systems, including the integrated photovoltaic construction operations (bipv), the photovoltaic construction enterprise (bapv), the operation of civil roof power stations for household power generation, the business and commercial operation of roof stations for power generation, the operation of photovoltaic agriculture applications, the electrical curtain wall and mobile energy products with photovoltaic products。
