How Many Solar Panels Do You Need to Offset an Electric Vehicle?

Charging an electric vehicle (EV) with solar power is one of the smartest ways to reduce both your energy costs and carbon footprint. In most cases, an EV driven 12,000–15,000 miles per year will use about 3,000–4,000 kWh of electricity annually. To cover that charging entirely with solar, most homeowners need 8–12 solar panels, depending on panel wattage, roof orientation, and local sunlight.

If you already have a solar array, your installer can review your usage and determine whether expanding the system is worthwhile.

Offsetting EV charging with solar not only lowers your operating cost—it also ensures your clean vehicle is powered by clean energy. It’s a simple upgrade that delivers long-term savings and a more sustainable daily drive.
