How to Charge an Electric Car with Solar Panels

Pairing an electric vehicle with solar energy is one of the smartest moves you can make in 2025. At RenovaEnergy, we explain how to charge your EV at home using solar panels—saving money and reducing your environmental impact with clean energy from your own rooftop.

Can you charge an EV using only solar panels?

Yes, absolutely. The key is knowing how much energy you generate, when you produce it, and how to schedule your charging. It’s all about designing a system that matches your usage and adapting your routine.

What do you need to charge an EV with solar?

• A solar panel installation sized to your household and vehicle consumption
• A charging station (wallbox) compatible with your home and EV
• (Optional) A solar battery to store power for night charging

How many panels are needed to charge an EV?

It depends on the car model and how much you drive. As a general reference:

• 10,000 km per year requires around 1,500–2,000 kWh
• This translates to about 6 to 8 solar panels dedicated to EV charging

How much can you save?

If you charge with solar energy, your cost per kilometer is virtually zero. Compared to a gas car, you can save over €1,000 per year on fuel alone—plus lower maintenance costs.

What if I don’t have a solar battery?

That’s fine. You can schedule your charging during daylight hours. With a good excess energy compensation rate, you’ll still save significantly.
