Case Study: Energy Self-Sufficiency for a Family in Kleinmachnow
Shadows on solar systems: How power optimizers can help
Solar panels have gained significant popularity in Germany as an environmentally friendly way to save electricity. Installing solar panels on residential homes has become essential know-how for every German resident in the field of electricity generation, just as the use of wind turbines is common in agriculture. By 2025, no one will be surprised by the presence of these systems. Let’s take a closer look at why this can be beneficial for family home photovoltaic costs.
However, the question arises: which company should be chosen for the installation, and what price should you expect for a 10 kWp solar system? The answer is simple: Profisolar.
Let us introduce ourselves. Profisolar Bau GmbH is a German company founded in 2023, specializing in the installation of photovoltaic systems. We work nationwide with well-known companies in the solar industry and offer both DC and AC installations through certified partners.

Current Value in 2025
Solar system 10 kWp without storage: approx. €15,000.
Prices vary – quality and equipment make the difference here.
My recommendation: It is better to invest a little more in high-quality components. Every additional year of operation sustainably increases your return.
10 kWp photovoltaic system including storage: around €25,000.
The storage unit may initially be quite costly, but in the long run it pays off – after all, with your own electricity storage you noticeably reduce your ongoing electricity costs.
In short: The higher initial investment pays for itself over time. Basically, you can assume that after about half of its lifespan, your 10 kWp system will have amortized itself. It can then easily continue to operate for 30 years or more – and from that point on, you will receive your solar power practically free of charge.
This makes the investment costs of a 10 kWp PV system with storage truly interesting in the long term.
