Curious about the impact of solar panels on electric vehicle (EV) charging costs? A dedicated EV owner, who recently installed a home solar system, shares compelling insights from his experience. After driving 14,000 miles, he reveals some surprising data that offers a real-world perspective on solar-powered EVs.
On PeakD’s Solar Energy forum, user KSteem unveiled his findings from powering his 2024 Chevy Blazer RS AWD with home-generated solar energy. Over two years, he’s clocked more than 14,000 miles, averaging about 3.4 miles per kWh. “I don’t drive a whole lot of miles compared to some,” KSteem notes. He adds, “I like to punch it and feel the acceleration way too much, so you could say these are conservative estimates, lol.”
Comparing the costs of driving similar distances in a traditional vehicle, KSteem estimates expenses would reach approximately $2,100 at 20 mpg or $1,400 at 30 mpg. However, his solar-powered EV costs were significantly reduced to just $617.65 at an average of $0.15/kWh.
“So as you can see, generally half or one third the cost of gas for the vehicle,” KSteem explains, also highlighting additional savings from reduced maintenance needs such as oil changes and brake replacements, thanks to the EV’s regenerative braking system.
Remarkably, his only maintenance in two years was a tire rotation.
Analyzing the Data
The data visualization by Notebook LM outlines the costs of various charging sessions on KSteem’s Autel home unit. Even at peak demand rates, the maximum “top-off” charge remains under $10, with most sessions costing under $2.00.
“You will definitely want a Level 2 charger,” KSteem advises. He installed a 50 Watt 220-volt power breaker to facilitate his charger, which can recharge about 33 miles per hour. This setup ensures a full charge by morning, with a typical range of 285 miles from a full charge.
The Solar Impact
In 2025, KSteem’s home consumed 27.4 MWh but generated 17.5 MWh through solar, reducing his energy bills by around $2,300. His solar system generated more energy than his EV consumed, highlighting the advantage of producing one’s own fuel.
“How much do you spend on gas and oil for your legacy fossil fuel car?” KSteem asks, proudly noting his average monthly energy cost is less than two oil changes.
