Company Profile

Since its establishment in 2002, Shandong Longguang Tianxu Solar Energy (hereinafter referred to as "Tianxu") has always engaged itself in the R&D, production, sales and service of high borosilicate glass tubes and new energy products including solar water heaters, solar vacuum tubes, solar heat collecting project, air source heat pump, photovoltaic products, etc.

Tianxu has 10 sets of electric furnaces, 70 sets of solar vacuum tube production line and 3 sets of solar water heater production lines. The annual output has reached one million tons of high borosilicate glass, over 16 million solar vacuum tubes makes Tianxu the largest manufacturing base of high borosilicate glass tubes and solar vacuum tubes.

In 2015, Tianxu established a joint venture company with Beijing Tsinghua Solar - the solar vacuum tube technology initiator in the world. The newly established company has the world's most advanced solar vacuum tube production lines.
