Charging an electric car at home with solar panels – does it really work?
Jun 19, 2025
Today, you no longer have to search long for green license plates while navigating the roads, as more and more people are choosing electric cars, and it's becoming evident. Thus, the question arises more frequently: how can we use this in a greener, more efficient, and sustainable way? For many, the answer is straightforward: with solar panels. But does charging an electric car at home with solar energy actually work? And if so, how can this be done effectively?
Green energy for your car – a logical step if you're already generating electricity at home
If you have solar panels on your roof, you are already using part or all of your own energy. Why not use this to charge your car as well? Solar energy is free (of course after the installation costs are recouped), and it is also clean – it does not pollute the air, it is not noisy, and in the long run, it is much more economical than traditional energy sources. Charging an electric car at home with solar panels is a logical continuation of this line of thought. It should also be mentioned that the energy generated by the solar panel is not constant, but this is where energy management and the range of smart charging options come into play. A system like Voltie has been developed to make the best use of the available green energy.
What charging modes are available if you want to charge with solar panels?
Voltie chargers offer three modes tailored for solar systems:
Green mode – Starts charging only when there is excess energy generated exclusively by the solar panels available. This way, your car really charges 100% green.
Eco mode – Continuously senses how much renewable energy is currently unused and supplements it from the grid as needed. This allows for faster charging while still being environmentally conscious.
Dynamic mode – Monitors the total energy consumption of the home and regulates the charging so as not to overload the system, while also optimally utilizing the generated energy.
As you can see, you can vary the different settings according to your needs. This is useful in several respects: you can save energy and money, while also easing the load on the grid and the vehicle's battery. You don't have to manually juggle the timings, the system takes care of that for you.
How to align charging and production?
You will achieve the best results if you can time the charging for the period of the day when production is highest - usually between 10 AM and 3 PM (during these hours, the intensity of sunlight is typically the greatest).
With the Voltie app, you can easily set this up, and you can even plan for days or weeks ahead. For example, if you don't use the car on the weekends but the sun is shining, you can schedule it to charge only when there is the most solar energy.
The system will also show how much energy you used from solar panels on a given day, and how much savings or CO₂ offset it represents. This feedback is particularly useful and motivating, as it makes visible how much you have done for the environment.
Charging an electric car at home: green, smart, simple
As you can see, solar charging works well, and it's one of the best decisions if you use an electric car. Moreover, with the Voltie system, it doesn't require any special technical knowledge: everything is easy to set up, the operation can be automated, and the data can be transparently tracked.
