How does an electric car affect the economy in combination with solar panels?

When you combine an electric car with solar panels, you can achieve even greater financial benefits while making your energy supply greener and more independent. A normal household with an electric car typically has an annual electricity consumption of approx. 11,000 kWh – of which the electric car can use between 2,000 and 4,000 kWh depending on driving patterns. Here, we often recommend a solar panel system of around 10 kWp to cover both the household's regular consumption and the charging of the electric car.

Charging and optimization in practice

On a typical weekday, you can charge your electric car primarily between 3 PM and 7 PM, when the solar panel system is still producing electricity. On weekends and holidays, when the family is often at home, the electric car can be charged almost all day directly from the solar panels – completely free and green. With battery storage, you can also store solar energy produced midday and use it for charging in the evening, meaning you minimize the use of expensive electricity from the grid. At the same time, our AI control system ensures that surplus electricity is automatically sold to the grid at favorable prices, and you can follow the entire process live via your app. This intelligent control means that your solar panel system not only saves you money but also increases your flexibility and makes electric car charging as economical and simple as possible.

Visualization: Monthly financial return without and with an electric car

Conclusion: Investing in solar panels is financially advantageous both with and without an electric car, but the extra load from the electric car significantly increases your electricity consumption, which the solar panel system can cover and optimize via intelligent control. This means larger monthly savings, increased independence from electricity prices, and a faster payback period.
