Shandong Yaoguo Solar Science and Technology Co., Ltd. (Short for Yaoguo Solar) was founded in September, 2009, located in No.88, Jixiang Road, New energy industry zone, Jisuo, Tengzhou, Shandong Province, China. The business scope of Yaoguo Solar is R&D, producing, wholesale, retailing and installation of solar energy products and solar energy products accessories, wind power equipment, solar thermal, optoelectronics, photovoltaic products.

Company introduced an advanced electric melting furnace production line, which supplies more than 20,000 tons high boronsilicate glass tube with all kinds of specification such as Φ37, Φ47,and Φ58 annually. Products are quite durable with high chemical stability, good mechanical performance, heat resistance and impact resistance,which ensure the stability of producing evacuated solar tubes.The glass tubes are environmentally friendly and energy saving, fully in line with the country's new energy industry policy, also means a very broad market prospects.
Solar vacuum tube is the core component of solar water heater and solar hot water project and heating engineering. Its performance determines the quality of solar heat utilization. Yao Guo Solar Thermal company introduced domestic advanced automated connecting tail machine, automatic eyelet machine, automatic washing machine, automatic drying machine and the the latest magnetron sputtering technology production line designed by Tsinghua University, to ensure the quality of coating, and make the thermal efficiency improved by more than 12%.Through strict control of vacuum technology, we can ensure the high heat efficiency and anti-attenuation performance of the solar evacuated tubes. Because of the advanced equipments and strict management,various types of vacuum tubes produced by Yaoguo have the characteristics of high temperature resistance, cold resistance, fast heating and so on.
