Voltaic Portable Solar Laptop Kit 17WK Panel and V72 Universal Laptop Battery - V17W72

Sold Out - Backorder Available

The Voltaic 17 Watt Charger Kit with 72V Battery provides solar power for Laptops and other smaller devices.


17 Watt Panel Kit provides more solar power for faster charging than the 10W Fuse or Array, but it does not come with a bag for storage. However it easy to mount on roofs etc and run the power cable inside to your battery. The solar panel generates power whenever there is sunlight and your battery stays dry. If your laptop is a power hungry and you need a bit more power than the Array or 10W Fuse, this is a good option.


The Kit includes :

  • A 17 watt solar panel
  • A V72 battery with adapters for mobile phones and laptops.
  • A rugged, lightweight and waterproof solar panel with an output of 17 Watts at 18V. You can easily slip this panel in a backpack for portability or mount it wherever you need power.
  • Solar power laptops, tablets and phones via the V72 laptop battery.
  • Pair with a charge controller to power 12V lead-acid batteries.
  • Pair with a car charger socket and camera cradle such as the Freeloader Camcaddy for charging large video camera batteries.

See Voltaic's blog regarding solar charging a Panasonic Toughbook, it mentions the 15W solar panel which has now been upgraded to this 17 Watt panel. Please also note the comments below regarding applications and charge times.

Applications and Charge times

With a few exceptions for rugged laptops, Voltaic recommend charging laptops via a battery like the Voltaic V72, not directly from a solar panel. Cameras can be charged directly from the panel as most camera cradles are looking for 12 to 24 Volts.

  • Approximate Charge Time from 17-Watt Panel**
  • Voltaic V72 Battery: 7 hours
  • Smartphone via Voltaic battery: 1-2 hours
  • Digital Camera: 1-3 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.

You can calculate the Watt hours of the battery(s) you'd like to charge. For every Watt of panel it takes 2.5 hours of direct, clear sun to power about 1 Watt hour of battery charge.
