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

Why photovoltaics and e-mobility harmonize perfectly

Using solar power for electric vehicles is a clever way to reduce costs while also contributing to environmental protection. By using the 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 that runs on solar power is almost emission-free. Unlike vehicles with combustion engines that require fossil fuels, your electric car uses a renewable energy source that is environmentally friendly and almost inexhaustible: the sun. By combining photovoltaics and e-mobility, you can significantly reduce your CO₂ footprint and actively contribute to climate protection.

cost savings through solar power

A key benefit of this combination is the ability to significantly reduce your electricity costs. If you charge your electric car with self-generated solar power, there are no additional costs once the system is installed. Compared to public charging stations, where electricity prices are higher, or electricity from the grid, 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 the home grid or stored in a battery storage unit. This electricity can then be used to charge your vehicle via a wallbox, i.e. a charging station for electric cars.

direct charging during sunshine hours

The most effective way to charge your electric car with solar power is to charge it directly during the hours of sunshine. 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.

use of a battery storage system

A battery storage system allows you to store excess solar power and use it later - for example in the evening or at night when the sun is not shining. This means you can charge your electric car even when the system is not producing electricity. This flexibility increases your own consumption of solar power and makes you less dependent on the power grid.

Intelligent charging control

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

How much electricity does an electric car need?

The power requirement of an electric car varies depending on the model, but is on average around 15 to 20 kWh per 100 kilometers. If you drive 15,000 kilometers per year, you will therefore need between 2,250 and 3,000 kWh of electricity per year. A typical photovoltaic system with an output of 5 to 10 kWp can easily cover this requirement, so you can charge your electric car almost entirely with self-produced solar power.

Tips for the optimal combination of photovoltaics and e-mobility

• Properly dimension your photovoltaic system: Make sure your photovoltaic system is sufficiently dimensioned to cover the electricity needs of your household and your electric car. Bear in mind that you may need more electricity if you regularly drive long distances.
• -Consider storage solutions: A battery storage system can increase the self-consumption of your solar power by storing excess electricity that can later be used to charge your electric car.
  
• Use intelligent charging systems: By using intelligent wall boxes, you can control the charging process so that your electric car is charged primarily with solar power. This way you avoid unnecessary grid power consumption and optimize 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 mobile in an environmentally friendly and cost-effective way. By using solar power to charge your electric car, you can significantly reduce your operating costs while actively contributing to reducing CO₂ emissions.
