What is the efficiency of PowerFilm solar panels?

Overall efficiency is strongly dependent on the module design configuration which determines the percentage of the area which is actually collecting sunlight. You can use 5% as a starting point. We have ongoing research and development programs to continue to improve the efficiency of PowerFilm panels. Note: There are widely varying standards for panel efficiency numbers. We encourage you to test actual commercially manufactured panels on a consistent basis.
