Several years ago, when gas prices were higher and an industry need arose to reduce costs and seek alternative solutions, conversations about harnessing the sun intensified. Combined with advances in electric vehicle technology, the possibilities of what manufacturers and fleets could do in this realm began to grow.
Solar power began to be used to extend the range of some electric and plug-in hybrid electric vehicles. And a full-size electric pickup truck using solar to extend its range was introduced at the 2014 North American International Auto Show.
Given the evolution of solar power use in vehicles over the years, where are we today?
As it turns out, on a slightly different course than one may have assumed. Rather than focus on the use of solar to add range to electric vehicles, utility fleets are, for example, adding panels as components of larger energy management systems. Solar power may be used to recharge vehicle starting and auxiliary batteries. It also can supplement battery charging while a vehicle is being driven or while it’s stopped – a valuable feature where legislation may prohibit idling. Additionally, solar power paired with an inverter system converts DC battery power to AC household power to charge cordless tools, laptops, test equipment and other work truck loads that require AC power without draining the battery.
