Upsolar was established by Zhe Jiang in Hong Kong in 2006 and the company focuses on providing outstanding photovoltaic module solutions.

In leading German Öko-Test magazine's results, released in April 2010, only four module manufactured scored a “very good” top rating, and Upsolar was the only one of seven Chinese companies to achieve this. The tests, conducted by Photon Laboratory on behalf of Öko-Test, focused on the actual power output compared to the data sheets, tolerances, module efficiency, cell quality and presence of micro-cracks.

All Upsolar modules are fully MCS certified and offer great value for money.
