The perfect combination of photovoltaics and e-mobility: How to charge your electric car with self-generated solar power

The combination of photovoltaics and e-mobility is a smart choice for anyone who wants to travel in an environmentally conscious and cost-effective way. With a photovoltaic system on your roof, you can use the generated electricity to charge your electric car almost free of charge. This combination of solar energy and electromobility not only offers financial advantages but also represents a significant step towards sustainability. In this article, you will learn how to charge your electric car with solar power and why this solution is so beneficial.

Why photovoltaics and e-mobility harmonize perfectly

Using solar power for electric vehicles is a smart way to reduce costs while also contributing to environmental protection. By using electricity from your photovoltaic system for your electric car, you become largely independent of rising electricity prices and reduce your dependence on external energy sources.

Sustainability and environmental benefits

An electric car powered by solar energy is virtually emission-free. Unlike vehicles with combustion engines that require fossil fuels, your electric car uses a renewable energy source that is environmentally friendly and virtually inexhaustible: the sun. By combining photovoltaics and e-mobility, you can significantly reduce your carbon footprint and actively contribute to climate protection.

Cost savings through solar power

A key advantage of this combination is the potential to significantly reduce your electricity costs. Charging your electric car with self-generated solar power incurs no additional costs once the system is installed. Compared to public charging stations, where electricity prices are higher, or to grid electricity, solar power offers an extremely cost-effective solution. The more you use the solar power yourself, the faster your photovoltaic system will pay for itself.

How does charging an electric car with solar power work?

Charging an electric car with solar power is straightforward. Your photovoltaic system generates electricity during the day, which is either fed directly into your home's electrical grid or stored in a battery. This electricity can then be used to charge your vehicle via a wallbox, i.e., a charging station for electric cars.

Direct charging during sunlight

The most effective way to charge your electric car with solar power is direct charging during daylight hours. If your photovoltaic system produces enough electricity during the day, you can feed it directly into your electric vehicle. This is particularly useful if you are at home or at work during the day and have a charging station there.

Using a battery storage system

A battery storage system allows you to store excess solar power and use it later – for example, in the evenings or at night when the sun isn't shining. This way, you can charge your electric car even when the system isn't producing electricity. This flexibility increases your self-consumption of solar power and makes you less dependent on the grid.

Intelligent charging control

Modern wallboxes offer intelligent charging control that ensures your electric car is charged primarily when sufficient solar power is available. The wallbox optimizes the charging process so that the electricity from the photovoltaic system is used as efficiently as possible and the use of grid power is minimized.

How much electricity does an electric car need?

The electricity consumption of an electric car varies depending on the model, but averages around 15 to 20 kWh per 100 kilometers. With an annual mileage of 15,000 kilometers, you would therefore need between 2,250 and 3,000 kWh of electricity per year. A typical photovoltaic system with a capacity of 5 to 10 kWp can easily cover this demand, allowing you to charge your electric car almost entirely with self-generated solar power.

Tips for the optimal combination of photovoltaics and e-mobility

• Properly sizing your photovoltaic system: Ensure that your photovoltaic system is adequately sized to cover the electricity needs of your household and your electric car. Keep in mind that you may require more electricity if you regularly drive long distances.
• -Consider storage solutions: A battery storage system can increase your self-consumption of solar power by storing excess electricity that can later be used to charge your electric car.
  
• Utilize intelligent charging systems: By using smart wallboxes, you can control the charging process so that your electric car is primarily charged with solar power. This avoids unnecessary grid electricity consumption and optimizes your solar system for maximum efficiency.

Conclusion: The ideal combination for sustainability and cost savings

Combining photovoltaics and e-mobility is one of the best ways to be both environmentally friendly and cost-effectively mobile. By using solar power to charge your electric car, you can significantly reduce your operating costs and actively contribute to reducing CO₂ emissions.
