"U.S. Soldiers have been using solar power in the Afghanistan war for a couple of years now, with everything from solar backpack kits to large stationary arrays. One project especially worth noting is a group of ten 28-kilowatt hybrid solar/diesel generators that have been deployed for Special Forces Soldiers in remote outposts. When you tote up the benefits, it’s clear that solar power is a winner, at least in war zones.
1. Solar Power Saves Money
Richard G. Kidd IV, deputy assistant secretary of the Army for Energy and Sustainability, recently described the project in detail for David Vergun of the Army News Service.
One key benefit, of course, is cutting down on the cost of fuel. According to Kidd, the overall daily fuel use per soldier averaged one gallon during WWII and now it has zoomed up to 20 gallons. A good chunk of that amount goes to electricity needed for powering today’s geared-up operations.
The hybrid solar/diesel units, provided by the company SunDial Capital Partners, cut that in half, to roughly 10 gallons.
Given the high cost of shipping fuel to remote outposts in Afghanistan ($400 per gallon, according to the Pentagon), it’s no surprise that the units paid for themselves in less than three months."
