* Panel output is computed from cell manufacturer's data based on 0% reduction of cell efficiency after packaging of cell strings. Electrical output tolerance +/- 10%. Under irradiance of 100 mW / sq. cm, spectrum of 1.5 air mass, at 25 degrees Celsius, as per cell manufacturer's specifications.
Useful Tips
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.
