Energy for your homeOne system, one quote.

Owning a house means living with energy questions. The heating is old, electricity prices are rising, and perhaps an electric car is coming soon. And every provider sells only its own part: one the solar system, another the heat pump, a third the wallbox.

We see it as one system. Solar system, battery storage, EV charger and heat pump all use the same electricity. When they are matched to each other, more of your own solar power stays in the house. That is why every project with us starts with a free site visit.

What matters to homeowners

From conversations with homeowners we know three worries: the cost, the subsidies and trust.

Cost: A price without a site visit is an estimate. After the visit you receive a binding quote within 72 hours. It states capacity, yield, subsidies and payback, calculated with your consumption.

Subsidies: The federal one-off payment (Einmalvergütung, EIV) from Pronovo and, depending on canton and commune, further contributions help with the investment. We submit the applications. On request, we pre-finance the subsidy. For tax too, in most cantons you can deduct the investment in an existing house.

Trust: You get a site visit instead of a quote based on a satellite image. Our own installers build the system. We are a member of Swissolar, the Swiss solar energy association. And from the first conversation to commissioning, you have one fixed contact person.

The solar system as the foundation

It all starts with the roof. A single-family home usually has room for 8 to 15 kWp. We check orientation, pitch, shade and the condition of the roof covering. If the roof refurbishment is due anyway, we plan both together. You will find everything important under solar systems and photovoltaics.

Without further measures, a household uses only part of its own electricity directly, and the grid operator pays for the rest at a lower tariff. This is exactly where the other building blocks come in.

Battery, EV charger and heat pump

• Battery storage: Power from midday covers the evening. More under battery storage.
• EV charger: An electric car needs around 2,000 to 3,000 kWh a year. With an EV charger that detects surplus power, you charge with sunshine.
• Heat pump: It heats and makes hot water using electricity. Together with the solar system, your energy costs fall the most. You will find information on the heat pump on its service page.
• Controls: An energy manager switches on the boiler, wallbox and heat pump when the sun is shining.

You do not have to buy everything at once. What matters is that we plan from the start so that later building blocks can be added without rebuilding. If you start with the solar system today and buy an electric car in three years, you should not have to open up walls again.

Backup power: lights on during a grid outage

A normal solar system switches off during a grid outage for safety reasons. If you do not want that, choose a battery that supports backup power. It keeps important loads running, for example the fridge, lights, internet and the heating controls.

How much backup power you need is a matter of preference. It is worth settling this before building, because the meter cabinet has to be prepared for it. At the site visit we discuss which loads should be covered and what that means for battery size and distribution.

What happens at the site visit

We come at an agreed time, and it usually takes about an hour. On the roof we measure the usable area and check shade and roof covering. In the cellar we look at the meter cabinet and the boiler room: is there enough space for the inverter and battery? Does the fusing fit? We also ask about your consumption, your plans for a car and heating, and what matters to you.

You do not have to commit to anything. Afterwards you get the quote and decide in your own time. If you have questions, call us.

How the project runs

1. Enquiry: online in a minute or by phone.
2. Site visit: we check the roof, meter cabinet, boiler room and consumption. Free and with no obligation.
3. Quote in 72 hours: binding, with yield, subsidies and payback.
4. Notification and grid operator: we submit everything for you.
5. Installation: our own installers, with a fixed date. Depending on the size of the system, installing the solar system usually takes about a week.
6. Commissioning: we show you the system and the app where you see yield and consumption.

Do you already have a system? Then we check whether an extension of the solar system or a retrofitted battery is worthwhile. That also starts with a site visit.

The next step

Enter your postcode in the appointment form. We will get in touch and arrange the free site visit. After that you know what is possible in your home, what it costs and what it brings you. You only have to decide once you have the quote.
