There are many factors that go into the how much power you are able to draw from your solar panels, and many are related to the design and orientation of your solar array. With that in mind, a safe average to assume with PowerFilm technology is 5%. Flexible panel technology, however, is still young compared to rigid panels, and as such is advancing all the time. There are widely varying standards within the industry for solar panel efficiency ratings and we encourage you to test different panels to find their actual power output.
