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.

We are now working on new solar panels with highly increased efficiency potential that could be used nationwide.

During the last two years, Spectrum carried out many installations with the use of E20 modules. The series could generate more power within a same amount of space, in comparison to other panels. With E20’s power-tolerant cells and compatibility with transformer-less inverters, Spectrum’ technicians were further geared to install high-performance and money saving equipment for homes.
