EV Chargers
Honest answers from our certified engineers — costs, permits, savings and everything in between.
Questions about home EV chargers: Wallbox, Tesla Wall Connector and Growatt.
Are there grants for home EV chargers in Spain in 2026?
The national MOVES III programme closed to new applications at the end of 2025, and there is currently no direct state grant for home charging points. In 2026 you can still deduct 15% of the installation cost of a charging point in your income tax return (IRPF), on a maximum base of €4,000. Check the current conditions with your tax adviser.
Can I charge my car from my home battery?
It is possible, but rarely the best use of a home battery: a car can empty a typical 5–15 kWh battery in an hour or two, leaving nothing for the house in the evening. We usually set up the system so the car charges from daytime solar surplus and the battery is kept for the home at night.
Can I charge my electric car with solar panels?
Yes. With a smart charger and an energy meter, the car charges from the solar power your home is not using. It works best when the car is parked at home during the day. You can choose solar-only charging, or solar topped up from the grid to keep a minimum charging speed.
Can I install a charger in a community garage?
Yes. Under article 17.5 of Spain’s Horizontal Property Law, a charger for private use in your own parking space needs only prior written notice to the community, not a vote. You pay for the charger, the installation and the electricity, and the work must comply with the electrical regulations (ITC-BT-52).
Do I need a 7.4 kW or an 11 kW charger?
Most homes on the Costa del Sol have a single-phase supply, which allows up to 7.4 kW, enough to add about 40 km of range per hour and fully charge most cars overnight. An 11 kW charger needs a three-phase supply and a car that accepts 11 kW AC. We check both before recommending a charger.
Does the Tesla Wall Connector work with other electric cars?
Yes. The European Wall Connector uses a standard Type 2 connector and charges most electric vehicles. The most advanced app features are for Tesla cars, but other EVs charge normally.
How long does it take to install a home EV charger?
After a free survey and a written quote, a standard home installation usually takes 1–2 days, including the dedicated circuit, protections, energy meter, app setup and a test charge with your car. Longer cable runs or community garages can take a little more time.
What warranty do I get on an EV charger installation?
The charger has its manufacturer warranty, which depends on the brand and model (for example, 4 years for the Tesla Wall Connector in residential use). On top of that, KiDi Solar gives a 5-year warranty on the installation work, and as a local installer we handle any warranty claims for you.
Which home EV charger is best for a villa on the Costa del Sol?
It depends on your car, your supply and your solar system. With solar panels, Wallbox and Growatt offer the most flexible solar-surplus charging; with a Growatt solar system, Growatt THOR keeps everything in one app. For Tesla owners who mainly charge at night, the Tesla Wall Connector is simple and robust. After a free survey we recommend the charger that fits your home.
Will I need to increase my contracted power?
Not always. A charger with dynamic load balancing reduces its charging power whenever the house needs more, so the main switch does not trip. In many homes this avoids raising the contracted power and the higher fixed monthly charge that comes with it. We review your bills and recommend the cheaper option.
