An electric car changes how your home uses energy. A typical EV on the Costa del Sol needs 2,000–3,000 kWh a year, often more than a pool pump, and how and when you charge it decides whether that energy costs you money or comes almost free from your own roof.
At KiDi Solar we install home EV chargers from three manufacturers: Wallbox, Tesla and Growatt. In this guide we explain how they differ, which one suits which home, how to charge from solar panels, and what Spanish rules, contracted power and grants mean for you in 2026.
Quick answer
No single charger is best for every home. The right choice depends on your car, your supply (single or three-phase), your contracted power, whether you have or plan solar panels, and where you park. As a starting point:
How home EV charging works
At home you charge with alternating current (AC). The wall charger, technically a Mode 3 charging point, does not convert the energy itself: it safely supplies AC power to your car, talks to the vehicle, and switches the power on only when everything is connected correctly. The car’s own on-board charger then converts it to DC for the battery. In Europe almost all home chargers and cars use the Type 2 connector.
Your car sets the speed limit
A charger can never deliver more power than your car’s on-board charger accepts. Many electric cars accept 11 kW AC, some accept 22 kW, and plug-in hybrids are often limited to 3.7–7.4 kW. Installing a 22 kW charger for a car that accepts 11 kW brings no benefit, so we always check your vehicle first.
Why not just use a normal socket?
A household socket can charge a car slowly (around 2–2.3 kW), but it is not designed for many hours at high load every night. A dedicated wall charger on its own protected circuit is safer, roughly three to five times faster, and adds scheduling, app control, load balancing and solar charging.
Single-phase 7.4 kW or three-phase 11 kW?
Most homes on the Costa del Sol have a single-phase supply, which allows up to 7.4 kW of charging. Larger villas often have three-phase, which allows 11 kW, or 22 kW where the supply and the car allow it.
| Charging power | Supply needed | Range added per hour* | Typical use |
|---|---|---|---|
| 3.7 kW | Single-phase (16 A) | about 20 km | Plug-in hybrids, low daily mileage |
| 7.4 kW | Single-phase (32 A) | about 40 km | Most homes: a full overnight charge |
| 11 kW | Three-phase (16 A) | about 60 km | Villas with three-phase supply, larger EVs |
| 22 kW | Three-phase (32 A) | about 120 km | Only for cars that accept 22 kW AC; mainly businesses |
For most drivers 7.4 kW is plenty: covering 50 km a day takes well under two hours of charging. The bigger question is usually not speed but when you charge, and whether your contracted power can handle the car and the house at the same time.
Charging your electric car with solar panels
The Costa del Sol is one of the best places in Europe to drive on sunshine. A home solar system produces most of its energy in the middle of the day, and a smart charger can send the surplus, the energy you would otherwise export to the grid for very little, straight into your car.
How solar-surplus charging works
A small energy meter in your consumer unit measures, second by second, how much power your home is exporting. The charger then adjusts its charging current to match the surplus. Depending on the charger, you can choose:
- Solar only: the car charges only from surplus solar power; slower, but practically free.
- Solar plus grid: solar first, topped up from the grid to keep a minimum charging speed.
- Scheduled: charge at night in the cheapest tariff period when you need a full battery by morning.
One technical detail matters: an EV usually needs at least about 1.4 kW on single-phase (6 A) before it starts charging, and about 4.1 kW on three-phase. Smaller solar systems, or cloudy winter days, may not reach that threshold, which is why many owners use the solar-plus-grid mode.
How much can solar cover?
It depends mostly on when the car is at home. If it is parked during the day (you work from home, are retired, or have a second car), solar can cover a large part of your annual charging. If you commute and charge only at night, the solar energy has to go through a home battery first, or you charge from the grid in the cheapest tariff period.
As an example, a car driving 15,000 km a year uses about 2,700 kWh. At a typical household electricity price of around €0.15–0.20 per kWh, that is roughly €400–550 a year if charged entirely from the grid. Every kWh you move to solar reduces that bill, and it improves the payback of your whole solar system, because you use more of your own energy instead of exporting it.
Can I charge my car from my home battery?
Technically yes, but it is rarely the best use of it. A home battery of 5–15 kWh can be emptied by a car in an hour or two, and the energy then is not there for your evening lighting, cooking and air conditioning. We usually configure the system so the car takes solar surplus during the day and the battery is reserved for the house at night.
Wallbox: smart chargers from Barcelona
Wallbox was founded in Barcelona in 2015 and has become one of the best-known home EV charger brands in Europe. Being a Spanish company, its chargers, app and support are well established in Spain, and it has the widest range of the three brands we install.
Product lines we install
- Pulsar range: compact home chargers, single or three-phase, up to 22 kW, with Wi-Fi and Bluetooth control through the myWallbox app. The latest Pulsar Max adds stronger connectivity and is designed for future features.
- Commander range: chargers with a touchscreen and user identification, suited to shared garages, communities and businesses.
- Quasar range: bidirectional chargers that can send energy from the car back to the home. Vehicle compatibility is still limited, so we assess these case by case.
Strengths
- Eco-Smart solar charging: charge from solar surplus only, or a mix of solar and grid, with an energy meter.
- Power Boost dynamic load balancing: the charger slows down when the house needs power, so you can often avoid raising your contracted power.
- Very complete app with scheduling, statistics and remote locking.
- Spanish manufacturer with local support and wide spare-part availability.
Things to consider
- Solar charging and load balancing need an additional energy meter, which we install with the charger.
- Some features depend on the exact model and app version, so we confirm what your unit includes.
Best for: homes with solar panels that want flexible solar-surplus charging, and properties where contracted power is tight.
Tesla Wall Connector: simple, fast and robust
The Tesla Wall Connector is Tesla’s home charger. It is designed first for Tesla cars, but the European version uses a standard Type 2 connector and charges most other electric vehicles as well, so it remains a good choice if you might change brand in the future.
What it offers
- Up to 22 kW: 7.4 kW on single-phase and 11 kW on a typical three-phase supply, up to 22 kW where the supply and the car allow it.
- Tethered cable with a slim connector, for indoor or outdoor mounting.
- Wi-Fi and the Tesla app: scheduling, charging data and automatic firmware updates.
- Power management: several Wall Connectors can share one supply, which is useful for two-EV households.
- 4-year warranty for residential use, one of the longest in the market.
Things to consider
- Charging from solar surplus with a non-Tesla solar system is not its strength. If solar charging matters most to you, Wallbox or Growatt are usually the better fit.
- Dynamic load balancing with the rest of the house is more limited than on Wallbox or Growatt, so we check your contracted power carefully.
- The richest app features are for Tesla cars; other EVs charge normally but with fewer extras.
Best for: Tesla owners who want a clean, reliable plug-and-charge experience, and two-Tesla households.
Growatt: EV charging that talks to your solar system
Growatt is best known for its solar inverters, and it is the inverter brand we install most often. Its THOR range of AC chargers is designed to work alongside a Growatt solar and battery system, so the inverter, the battery and the car are all managed in the same ShinePhone app.
Product lines we install
- THOR AC chargers: single-phase models up to 7 kW and three-phase models at 11 and 22 kW, for homes, villas and small businesses.
- Versions with Wi-Fi, LAN or 4G connectivity and RFID card access, depending on the model.
Strengths
- Solar charging mode that uses only your solar energy to charge the car, increasing self-consumption.
- One app for solar panels, inverter, battery and car, which makes daily use simple.
- Load balancing adapts charging to your home’s available power to avoid tripping the main switch.
- Very good value, especially when added to a new Growatt solar system.
Things to consider
- The biggest advantages appear with a Growatt inverter. With another inverter brand, Wallbox is often the more flexible choice.
- The app and accessories are less polished than Wallbox or Tesla for drivers who want advanced charging statistics.
Best for: homes with a Growatt solar system, or planning one, that want one simple app and the best value.

Rules, contracted power and grants in Spain
Installed to the electrical regulations
In Spain, EV charging points are covered by the low-voltage electrical regulations (REBT), specifically instruction ITC-BT-52. In practice that means a dedicated circuit, the correct cable size for the distance, its own overcurrent protection and residual current protection suitable for EV charging, and the installation documentation required for your type of property. Our electricians handle all of it.
Do you need more contracted power?
A 7.4 kW charger alone uses more power than many homes have contracted. There are two solutions: increase your contracted power (potencia contratada) with your electricity company, or install a charger with dynamic load balancing that reduces charging power whenever the house needs it. In many homes load balancing is enough, and it avoids higher fixed monthly charges. We check your bills and recommend the cheaper option.
Community garages
Under Spain’s Horizontal Property Law (article 17.5), installing a charger for private use in your own space in a community car park requires only prior written notice to the community, not a vote. The owner pays for the charger, the installation and the electricity used.
Grants and tax deductions in 2026
- MOVES III has ended: applications for the national programme closed on 31 December 2025, and there is currently no direct state grant for home charging points.
- 15% income tax (IRPF) deduction: in 2026 you can still deduct 15% of the cost of installing a charging point, on a maximum base of €4,000. It is applied in your tax return, so check the current conditions with your tax adviser.
- Programmes change often; we tell you what is available when we prepare your quote.

Warranty and service on the Costa del Sol
Your charger has two layers of protection: the manufacturer warranty on the charger itself (see the table above), and KiDi Solar’s 5-year installation warranty on our work. As a local installer based in Marbella, we handle any warranty claim with the manufacturer and come to your home.
We install EV chargers across the coast, from Marbella to Málaga, Estepona, Benahavís and Sotogrande. See our Costa del Sol service area.
Outdoor chargers, heat and salt air
Many chargers on the coast are mounted outdoors or in open carports. We choose positions out of direct afternoon sun where possible, check the charger’s IP rating for the location, and use corrosion-resistant fixings and sealed cable entries near the sea.
EV Chargers — FAQ
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.
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.
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.
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.
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).
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.
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.
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.
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.
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.
