Powering Your Electric Vehicle with Solar

Powering Your Electric Vehicle with Solar

By Drew Chandler, Energy Specialist 

Getting Rid of Gas

So you ditched your gas guzzling internal combustion engine vehicle (ICE) for an electric vehicle (EV)–congratulations! In addition to being quiet, low maintenance, and fun to drive, EV’s powered by the electric grid are undoubtedly cleaner than their ICE counterparts. According to the US Department of Energy’s Alternative Fuels Data Center, the average gas-powered vehicle emits the equivalent of 11,435 lbs of carbon dioxide per year. An average EV charged by the electric grid in North Carolina, which is powered mainly by burning fossil fuels, is responsible for releasing roughly 4,185 lbs of CO2 into the atmosphere each year.

While EV’s powered by the electric grid offer close to a threefold reduction in emissions compared to ICE vehicles, this barely scratches the surface of an EV’s potential to decrease greenhouse gas emissions. Many of our EV driving clients want to take it a step further by using solar photovoltaics and battery backup, like Tesla Powerwall, to generate and store the electricity needed to power their vehicles, thus reducing their transportation related emissions to zero.

Charging EV’s with Solar Makes Sense

It may come as a surprise to people that it is not only completely feasible to power your EV with a home solar system, it is also usually cheaper than charging your car with electricity from the grid!

Below, we have put together a table showing what size solar array you would need to offset your EV’s charging needs, as well as the cost per kWh of solar electricity, and the cost per kWh of electricity purchased for the grid. Most solar panels have a 25-year power production warranty and will continue producing electricity well beyond the 20 years foretasted here.  *Below are estimations & averages, please contact us and we will provide a free customized analysis.
