With a photovoltaic system and wallbox from Helion. The experts at Helion will advise you and take care of the installation of your home charging station from A to Z, so you can charge your electric car quickly and safely with solar energy. Find out more here.

Not only can you charge your car independently of public charging stations and rising electricity prices, you also charge more cheaply and emission-free.

By increasing the electricity consumption, you are increasing your own consumption and, as a result, the profitability of your photovoltaic system. Surplus electricity is only fed back into the grid when your battery is fully charged.

In addition, your own solar electricity is up to 12 cents cheaper per kilowatt hour in Switzerland than electricity from the grid, so an electric car powered by solar electricity has less of an impact on your electricity costs.

The rule of thumb says one kWp per 1,000 kilometres of driving, which is about two to three panels.

But please note: that does not mean that this is the only criterion for the size of your photovoltaic system, since there are also other power-hungry consumers in the house. Basically, the recommendation is to cover the entire roof. The basic costs of an installation (administration, scaffolding, etc.) are always the same. The larger the photovoltaic system, the quicker it will pay for itself. It is also better to make full use of the roof with a view to the future, because electricity consumption will tend to increase (mobility, heating, etc.) and electricity costs are currently increasing rather than decreasing.

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 Helion’s cost overview or here to view the detailed solar calculator.

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 charging station calculator.

The charging time of your e-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)

Household socket up to 3.7 kW 8–14 hours

Charging station/wallbox 3.6 to 22 kW 2–6 hours

Are you a homeowner with a photovoltaic system installed on your roof? Then you can expect twice the benefits: by charging your electric car using your own PV system, you can double the rate you normally receive for your photovoltaic electricity (based on the mean electricity price in Switzerland).

We will reimburse you CHF 0.30/kWh for electricity charged at home – significantly more than the rate offered by local electricity suppliers. This means your PV system can become an attractive investment faster thanks to Clyde. You can find out more about the Clyde Energy Benefit here.

With the Helion ONE app, you can optimise your own consumption flexibly and profitably. By means of networked and remotely controllable devices and installations, you can not only control the lights or access to your home.

The devices use your solar power more efficiently and always keep an eye on your electricity consumption – be it for charging your electric car, for heating the house or for heating water.

Helion helps you with the installation of your wallbox and advises you on all topics relating to your PV system and renewable energy.
