A US-based, federal laboratory known as the National Renewable Energy Laboratory (NREL) recently tested our X-Series Solar Panels. It was found these panels have reached 22.8% in energy efficiency, which is much higher than the usual 15 to 18% ratings of other panels.
Aside from the latest X-Series test results, we also have existing lines of panels which exceeded the 15 to 18% usual efficiencies among other modules. The E19 panels could produce 19.5% and E20 were at 20%, while X21 and X22 had 21% and 22% respectively.
