Electromobility is becoming increasingly important. An important aspect is the possibility of charging your electric car with self-generated solar power. The combination of photovoltaic system and electric car offers numerous advantages and contributes to the energy transition.
Why charge electric cars with solar power?
- Environmental friendliness: By using solar energy, you significantly reduce your ecological footprint.
- Cost savings: Self-generated solar power is usually cheaper than grid power.
- Independence: You are less dependent on rising energy prices and can partially cover your electricity consumption yourself.
- Promoting the energy transition: With every PV system installed, you are making a contribution to the energy transition and the expansion of renewable energies.
What is needed?
To charge your electric car with solar power, you basically need the following components:
- Photovoltaic system: This generates the electricity.
- Storage (optional): A storage system makes it possible to store excess solar power and use it when needed.
- Wallbox: The wallbox is a special charging station for electric cars and ensures safe and fast charging.
- Energy management system: This system optimally controls the flow of energy between the PV system, storage and electric car.
How does charging with solar power work?
The solar power generated is first converted into direct current. The inverter then converts this direct current into alternating current, which is needed to charge the electric car. Excess electricity can be temporarily stored in a storage unit or fed into the public grid.
What are the advantages of an energy management system?
An energy management system optimizes the charging process of your electric car. It ensures that your vehicle is preferably charged with self-generated solar power and uses the stored power efficiently. It can also adjust the charging power to the current solar radiation and thus preserve the lifespan of your battery.
Maximizing self-consumption
- Time of charging: Preferably charge your electric car during the day when the sun is shining and your PV system is producing the most electricity.
- Dynamic charging: Use an intelligent wallbox and an energy management system to adjust the charging process to the current solar power production. This means that your electric car is preferably charged with self-generated electricity.
- Storage solution: A battery storage system can store excess solar power and use it for times when your system produces little or no electricity, such as at night.
Conclusion
The combination of a photovoltaic system and an electric car offers numerous advantages and is an important step towards a sustainable future. Through careful planning and the use of intelligent technologies, you can optimally use the self-generated solar power to charge your electric car and thus reduce your energy costs.
