More than half of the homeowners we talk to either own or are, in the near term, considering purchasing an electric vehicle. Part of the combinatorial interest -- clean energy + clean vehicle -- is values based. However, most homeowners who go solar and fuel their transport with sunshine do it for pragmatic reasons: Solar electricity is significantly less expensive than PG&E's energy, and fueling an electric vehicle is much cheaper than pumping gas. Here's a prior post quantifying the economics of solar + eVs.
Though the math is simple, the decision -- which car to purchase or lease, at what time, and how to size my solar system to cover my electric vehicle charging -- has more to it. To wit, there's a delightful new tool for California homeowners to determine if a solar-powered vehicle makes sense. In a few minutes, you can compare options and model the economics/scenarios. Take a peek, poke around, and (we're confident) you'll be impressed by the savings.
And, of course, feel free to contact us if you have questions about electric vehicles and the potential to power your eV with solar. We will perform a no-cost assessment for you, modeling various alternatives and quantifying the impacts.
