Included standard with Offgrid solar backpack.
Specifications for a Single Solar Panel (Many of our products have 2 of these panels)
Dimensions: 135 x 112 x 5mm
Weight: 4 ounces, 120 grams
Substrate Type: 3mm Aluminum/Plastic
Cell Type: Monocrystalline
Cell Efficiency: 18%
Open Circuit Voltage: 7.0V
Peak Voltage *: 6.0V
Peak Current *: 333 mA
Peak Watt.: 2.0 Watts
Connector: 3.5 x 1.1mm plug
Mount: 4 stainless steel screws
* 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.
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.
Approximate Charge Times from 2 Panels in Direct Sunlight*
Voltaic Battery Pack: 7 hours
iPhone or Smartphone via a Voltaic Battery Pack: 4-5 hours
Digital Camera: 4-8 hours
* Charge times may be increased in cloudy weather, high temperatures, or where panels are not angled towards the sun.
