Dimensioning according to the object
The solar power system is sized by our experts according to the electricity consumption of the site so that the economic benefit of the system is maximized. For domestic sites, this usually means a system of 3.0 – 17.0 kWp. For systems larger than this, it is a good idea to check with the grid company whether the system can be connected to the site.
When dimensioning, it is also a good idea to take into account, for example, future purchases of electric cars, heat pumps or other factors that significantly affect electricity consumption.
Solar panels are a profitable investment
Solar panels are a really profitable investment. At best, the return on investment is around 20%, even with the current low electricity prices. Payback periods are on average 5-8 years, depending on the project.
In addition to the price of electricity, the panels also save on transmission fees and electricity tax, and increase the value of the building.
