Wall box and photovoltaic system: The perfect combination

With the combination of a wall box and a photovoltaic system, you can charge your electric car from the comfort of your home – independently, affordably and sustainably. Any excess solar power not used in your home simply goes into the battery of your car.

Your advantages at a glance:

  • Increase your own consumption.

    Use the electricity generated by your photovoltaic system directly where it’s produced. That way, you reduce the amount of energy you have to feed into the grid – and your costs.

  • Save money.

    Solar power is much cheaper than electricity from public charging stations. Simply charge your electric car at home and benefit from lower energy costs.

  • Take advantage of incentive programmes.

    Many cantons in Switzerland provide financial support for the installation of photovoltaic systems and charging infrastructure.

  • 100% emission-free.

    Charge your electric car with clean solar energy – for maximum sustainability.

    • Home charging stations for every lifestyle

    For homeowners
    Installing a wall box in combination with a photovoltaic system is easy and efficient. With a high-performance charging station, you can store excess solar power directly in your electric car – ideal for a sustainable lifestyle and lower electricity costs.


    For co-owners and tenants
    Even if you rent in an apartment building, you can charge your electric vehicle from the comfort of your home. It’s important that you get consent from the property management or owners’ meeting prior to installation. Helion will then support you in the planning and implementation – from the technical solution to the billing system, for example via RFID cards.

    Why does a photovoltaic system for your electric car make sense?

    With a photovoltaic system on the roof of your house or garage, you can charge your electric car in an efficient and environmentally friendly way – and save money at the same time.

    One really clever aspect is that your electric car becomes an additional storage facility for your excess solar power. Instead of feeding unused energy into the grid, you can store it in your car’s battery, maximising your system’s efficiency. As soon as the battery is full, excess electricity is fed into the grid.

    Benefit twice – with the Clyde Energy Benefit

    Choose the ‘Premium – with electricity’ option when configuring your electric car and you can enjoy twice the benefits. We pay you 0.30 CHF/kWh for charging at home – considerably more than the rate offered by local electricity suppliers.

    Any questions?

    A wall box is essentially just an intelligent, high-performance electricity socket. The wall box is connected to the electricity grid and offers a safe and efficient way to charge electric vehicles.

    In an apartment building, the installation of a charging station requires the prior consent of the property management or a majority resolution of the owners' meeting. If several tenants or apartment owners are involved in the home charging station, it is advisable to have a user identification system (e.g. by means of an RFID card) that offers corresponding billing options for electricity consumption.

    As a tenant, clarify in advance with the property management what is to happen to the charging station or the corresponding facilities after the end of the rental period. Helion is happy to support you in your discussions with your management and will help you to find a suitable solution.

    If you as an apartment owner install a charging station at your own expense, it is advisable to have future operators of the charging station share the initial costs.

    Starting at around CHF 2,500, you can get a home charging station including the installation costs. However, the costs vary depending on the length of the connection cable, car make and model, number of parking spaces to be equipped, building type and parking area. Click here for the undefined.

    A PV system can be installed on a small roof of a single-family house for as little as CHF 19,500 (including subsidies and tax savings). This is a guideline only, because various factors can influence the price, such as the size of the roof and the output, the choice of solar modules, material costs and scaffolding (including the fuse box). In addition, the type of building, the size of your household and your electricity requirements also play a part. Click here for undefined or to view the undefined.

    The charging time of your electric car depends on three factors:

    1. Kilometres travelled per day
    2. Charging power of the charging station
    3. Charging technology of the car

    The charging speed depends on the number of kilometres driven per day. The fewer kilometres you have travelled with the electric vehicle, the less the battery needs to be recharged.

    Calculation formula for the charging time: charging time = battery capacity in kWh/charging power (kW)
