Electricity is good, but charging your car solar energy, it’s even better! In addition to saving money, it’s also a more environmentally friendly way to charge your car… But not all charging stations are the same. A well-known German association ADAC conducted tests on eight special Wallboxeswith an amazing result!

Recharge your car with solar energy

If you have your own photovoltaic installation on the roof you can charge your electric car at an unbeatable price. With such a system, your electricity production costs are only 10-12 cents per kilowatt-hour. Therefore, the installation pays off quickly! In France, you can get help depending on the region indicated on this government site.

But to charge solar electricity from its panels directly into your car’s batteries as efficiently as possible, you need Special wall box.

Several testing criteria

To make the right choice, ADAC tested eight suitable models against several criteria: their cost, their functioning and them level of reliability.

The overall rating is evaluated as follows: ” fine ” (a dark green), “FINE” (light green), “satisfactorily” (YELLOW), “sufficient” (orange) and finally “insufficient” (red).

The cheapest Wallbox is the best

On eight models were testedonly three Wallboxes have a phase switching system. This makes it possible to charge an electric car from an excess of generated electricity of only 1.3 kilowatts, while a fixed three-phase system requires at least 4.1 kilowatts.

Among only three products tested that offer this option directly from the factory, we find the one that also has the lowest price. It is about Wattpilot Home with Froniusdisplayed by price 938 euros in Germany. A quick look at the French sites shows little variation here, with slightly higher prices depending on the dealer (from €1,085 to €1,199).

But in addition to the attractive price, this particular model also has the best test result with 1.6 (the closer to 5, the better).

Call a professional if in doubt

In any case, ADAC recommends that you seek professional advice before purchasing such a production surplus solution. They will be needed in any case to install such a terminal on the network.

In addition, to ensure compatibility between equipment, it is better to buy all components from the same supplier. In all cases, such an installation must be planned before investing blindly. Take the time to evaluate the final cost and long-term profitability when researching your future installation!
