Voltaic 18 Watt Solar Laptop Charger Kit

Combine the V72 universal battery with three lightweight and waterproof 6 Watt solar panels to make an 18 Watt, 18 Volt solar laptop charger. Attach the panels to webbing or any thin material. (Voltaic have a blog post with a suggestion) If you're looking for a minimal, but ultra-tough and fast solarlaptop charging solution, this is it.  The kit includes:

  • 3 x 6W Solar Panels
  • 1 x 3 Panel Circuit Box
  • 1 x V72 Laptop Universal Battery with connectors

6 Watt Panel Specifications (single panel)

  • Dimensions: 220 x 175 x 5mm
  • Mass: 241 g
  • Substrate: 3 mm Aluminum/Plastic
  • Cell Type: Monocrystalline
  • Cell Efficiency: 18%
  • Open Circuit Voltage: 7.0 V
  • Peak Voltage*: 6.0 V
  • Peak Current*: 975 mA
  • Peak Power: 5.85 W
  • Connector: 3.5x1.1 mm plug
  • Mount: 4 stainless steel bolts

*Panel output is computed based on cell manufacturer's data assuming 0% reduction of cell efficiency after packaging of cell strings. Electrical output tolerance +/- 10%. Under irradiance of 100 mW/cm2, absolute air mass of 1.5, at 25 °C, as per cell manufacturer's specifications.


Applications and Charge Times

  • This is Voltaic's most powerful kit for charging laptops via the V72 battery. Since there are three panels, you should have a plan for managing them in your application (attach to fabric or some other material). This kit also works well for digital camera charging with a suitable charging cradle.
  • Approximate Charge Time from three 6 Watt Panels**
  • Voltaic V60 Battery (18V Setting): 7 hours
  • Smartphone via Voltaic Battery: 1 hours
  • Digital Camera: 2 hours

**For maximum power output, orient the panels towards the sun. When not angled towards the sun, output will be reduced. Dirt and scratches on the face of the panels will reduce the amount of light hitting the solar cells. Clean the panels with a damp non-abrasive cloth. Charge times are estimated based on optimal conditions and may increase in cloudy weather, high temperatures, or when panels are not angled towards the sun.
