Established in 1984, the 150l solar limited is one of china's early professional enterprises involved in the development, production, sale and servicing of solar thermal products. The funds registered are tens of thousands of dollars, mainly for solar photovoltaic products, solar photovoltaic products, coal-efficient stoves, etc. These include, inter alia, solar photovoltaic equipment, solar water heaters, large-scale solar water heaters, wall-mounted solar water heaters and biomass stoves. The marketing area covers the autonomous regions of hebei, henan, shanxi, shaanxi, xinjiang, nemong, hubei, liaoning, anhui and gansu provinces, and has established a well-established marketing network and after-sale service system. It has now developed into a powerful hebei province, with a highly marketed solar energy thermal power company. The company has a strong team of technology founders, headed by the senior engineer general zhao tsaily, who receives a special government allowance, which has resulted in the upgrading of the product and a steady improvement in its quality, which has been at an advanced level in the country for many years. In order to meet market demand and scale up production, a smart choice of $340 million has been made in the economic development areas of china, with 150l solar energy production research bases covering 145 acres, creating an automatic line for the production of 200,000 square metres of solar collectors annually, an automatic line for the production of 800,000 square metres of vacuum pipe solar water heaters annually and 100,000 coal-efficient stoves. The construction of integrated office buildings, research and development centres for thermal use of solar energy, production workshops, warehouses, etc., are well equipped and well equipped and integrated into research and development, production and marketing. A solid foundation has been laid for the development of solar energy carriers throughout the province. In order to optimize industrial structures and product upgrading, the company has signed a technical cooperation agreement with the south-east university for the joint research and development of a solar curvature curvature pv system, which has been patented for five inventions. The system can generate solar heat sources of more than 400°c and its industrialization will provide solar power for new technological areas such as solar thermal power generation, solar air conditioning and desalination。
