Tips of Use
For maximum power output, angle the panels towards the sun. When not angled towards the sun, power declines about 20%. When angled away from the sun, the power drops off 80-90%. Dirt and scratches on the face of the panels will reduce the amount of light hitting the solar cells. Clean them with a damp non-abrasive cloth.
