11 Frequently asked questions
Got questions? We have answers.
How much does a solar system for a single-family home cost?
A typical 8–10 kWp system costs about €8,500 to €13,000 depending on the roof and equipment. With a battery, most systems come to about €12,000 to €15,000. A wallbox starts at about €1,500. Private systems up to 30 kWp carry 0% VAT. You receive the exact price as a fixed price after the consultation.
Is my roof suitable?
South, east and west roofs are very well suited, as are flat roofs with tilted mounting. For north-facing roofs or a lot of shade, we check on site whether it is worth it. The roof check above gives you a first estimate.
Are there subsidies?
Private solar systems are exempt from VAT. For financing there is, for example, the KfW 270 loan “Renewable Energies”. Whether there are additional regional grants where you live, we check during the consultation.
How long does it take until the system is finished?
Usually 4 to 8 weeks, depending on component availability and the grid operator’s schedule. The installation itself usually takes only 1 to 2 days for a single-family home.
Is a battery worth it?
Without a battery you usually use only about a third of your solar power yourself, because the sun shines during the day but you often need power in the evening. With a battery it is usually about two thirds. Whether it pays off for you, we calculate in the quote.
Do you also work for businesses?
Yes. We plan and install systems for private and business customers, including on hall and flat roofs. For businesses we prepare a profitability calculation.
Who takes care of registration and paperwork?
We do: registration with the grid operator and the entry in the national energy register. You don’t have to worry about anything.
What happens if something stops working after installation?
We remain your contact after installation – we offer maintenance from €150. Modules carry a manufacturer's warranty of up to 30 years, inverter and battery 10 years.
