EV chargers: comfortable, safe charging tailored to you.
Charger for your electric car at home
We install turnkey chargers in single-family homes: charger, wiring, protections, legalisation and commissioning.
Before preparing the estimate we study:
- The vehicle model.
- The available power.
- The distance between the meter and the parking space.
- The cable routing.
- The required charging speed.
- The existence of solar panels.
- The possibility of future expansion.
The charger can be programmed to recharge at the most convenient times. In addition, the load balancing system analyses the instantaneous consumption of the home and assigns only the available power to the vehicle, avoiding increasing the contracted power.
Chargers for communities and companies
We design installations for community garages, companies and commercial fleets.
May include:
- One or several charging points.
- Balancing between chargers.
- User control and identification.
- Consumption tracking and billing per vehicle.
- Scalable pre-installation.
- Integration with solar panels.
We study uses and needs to size the right power and handle procedures with the community or grid operator.
Smart management of power
In many cases there is no need to increase the contracted power.
The load balancing system analyses the instantaneous consumption and assigns only the available power to the vehicle at any given moment.
When there are several chargers, the energy is distributed automatically among the connected vehicles. This makes better use of the existing power and avoids unnecessary fixed costs.
Charging with your solar surplus energy
An intelligent charger can adapt the recharge to the energy the photovoltaic installation is producing.
When there are surpluses, the system can direct part of that energy to the vehicle instead of pouring it into the grid.
Depending on the equipment and configuration chosen, you'll be able to:
- Charge using only solar surpluses.
- Combine solar energy and grid energy.
- Programme the charging during peak production hours.
- Limit the power used.
- Prioritise home or business consumption.
- Check the energy used from an app.
If you don't have solar panels yet, we can jointly design the photovoltaic installation and the charging point.
How we install your electric vehicle charger
1. Technical study and charger selection
We analyse usage needs, charging point location and vehicle model to recommend the most suitable equipment (power, connector, intelligent management).
2. Electrical routing design and protections
We plan the cable route from the electrical panel to the charging point and size the necessary protections to ensure safety and regulatory compliance.
3. Installation, power management and solar integration
We execute with our own team without subcontracting, configure the intelligent power management system and, where applicable, integrate the charger with your photovoltaic installation to take advantage of surpluses.
4. Commissioning, legalisation and training
We activate the installation, handle the necessary legalisation and explain the operation of the charger and the app so you can take advantage of all its features.
By combining these options you can drastically reduce the cost of your installation:
- Personal income tax deduction of 15% (individuals · RDL 7/2026): on the real cost of the installation, with a maximum base of €4,000. Independent and stackable with deductions for solar panels or heat pumps.
- Accelerated 100% depreciation (companies · RDL 7/2026): 100% depreciation of the investment in the first fiscal year.
- Factor de Insularidad 2026-2027 (Balearic Islands): up to 70% of the cost with a maximum of €2,500 (individuals) or €12,000 (businesses).
- Auto+ Programme (compatible): grants for buying the electric vehicle, complementary to the charger deduction.
Grants change depending on the autonomous region, the type of beneficiary and the project execution date. Before starting the work we review the open calls, the eligible expenses, the required documentation and the deadlines applicable to your case.
Commitment to electric mobility
We practise what we preach: if we recommend taking advantage of these grants, it's because we use them ourselves. We have added 100% electric vehicles to our active fleet, beneficiaries of the MOVES III Programme for efficient and sustainable mobility, contributing to the decarbonisation of our operations.

Frequently asked questions about electric vehicle chargers
Do I need to increase the contracted power?
Not always. A charger with dynamic power management can adapt charging to the power available after covering the consumption of the home or business.
How long does it take to charge an electric car?
It depends on the battery capacity, the power the vehicle accepts, the charger's power and the energy available in the installation.
Does SolarTradex handle the installation and legalisation?
Yes. We carry out the installation, configure the equipment and prepare all the documentation required for legalisation.
Can I charge using only solar energy?
Yes, there are CVE that allow this. These chargers need to read the current consumption through an external meter (the same one used for load balancing) and adjust the charging to exclusively use the available surplus energy, respecting the minimum and maximum charging limits of the connected vehicle.
In this way, the surplus fed into the grid is minimised as much as possible. With one important limitation: if the surplus is very low, the charger will not be able to use it. For example, with 1.3 kW of surplus, the CVE will not be able to inject it into the vehicle, as it is not enough to allow the vehicle to start charging.
This operating mode enables two modalities for managing solar surplus:
- Solar surplus only: the vehicle is charged exclusively with the surplus energy from the panels.
- Grid + surplus mix: a combination of grid energy and solar surplus, with the percentage predefined by the user.
This combination is compatible with the grants and subsidies in force for self-consumption installations with electric mobility.
Can I install a charger in my community parking space?
Installing an EV charger in a space of a community car park has two main options, both technically viable:
- CVE connected directly to your home meter: if there is access from the car park to your flat, an individual derivation is installed. The wiring to reach the space can be individual or collective (community pre-installation), depending on what the residents' community decides.
- Protection subpanel from the car park meter: a common subpanel is installed from which individual derivations run to each CVE of the car park spaces. Each user has their own consumption meter and independent bill.
The choice depends on the building's infrastructure, the number of interested neighbours and the community agreement.
These options are perfectly combinable with a collective self-consumption installation in the community: the solar surplus generated on the roof can feed the CVE in the car park, maximising savings for all neighbours.
Are there grants to install the charger?
Yes, there are several ways to reduce the cost of installing an EV charger at home. These are the main grants and tax advantages available:
- 15% income tax deduction (RDL 7/2026): you can deduct 15% of the cost of the charging point installation, on a maximum base of €4,000 — up to €600 in tax savings. This deduction is independent and cumulative with the deductions for photovoltaic installation or aerothermal.
- State electric mobility programmes (MOVES Plan and successors): direct grants for the installation of charging points, with amounts varying according to the type of installation and location.
- Regional and municipal programmes: in Catalonia and the Balearic Islands there are specific calls for electric mobility, as well as possible reductions in the municipal IBI (property tax) for homes with an installed charging point.
The most profitable combination is to install the charger together with solar panels, since in addition to the charger-specific grants, you can access the self-consumption grants and subsidies. Check the details of each route and see which are compatible with each other on our grants page.
