Energy For The Future

We’d be happy to calculate that for you – but most likely, yes! With continuously rising energy costs, investing in a solar system and benefiting from the dynamic electricity pricing it enables is an excellent alternative to becoming independent from the power grid.

To make an informed decision about investing in a solar system, energy storage, or a wallbox, simply fill out our online PV configurator. It’s an easy way to explore the potential of a photovoltaic system for your roof. Get a quick and straightforward analysis of the ideal system size, the number of modules required, a suitable battery with matching storage capacity, and the associated savings in costs and CO2 emissions.

In addition to planning, implementing, and managing your photovoltaic system, we also specialize in electromobility. Would you like to charge your electric car at home? With a wallbox installed by our experts, that’s no problem!

On average, we can complete your project within six weeks – from planning to final installation. However, the exact timeline depends on our current workload and the specifics of your project. We are happy to discuss and define the schedule with you in detail beforehand. Contact us today!

The cost of a solar system depends on several factors, including the size of the system, the condition of your roof, installation costs, and the choice of provider. Take advantage of regional subsidies or bank loans to reduce upfront costs. For example, KfW Bank offers low-interest loans for photovoltaic systems.

There are several funding opportunities in Berlin and Brandenburg to support the purchase and installation of solar systems:

KfW Funding: The KfW (Kreditanstalt für Wiederaufbau) provides low-interest loans and grants for private photovoltaic systems, applicable to both new installations and expansions of existing systems. Learn more here.

Berlin State Programs: The state of Berlin regularly offers funding programs to promote renewable energy. Check out current programs here.

Tax Benefits: By feeding surplus electricity into the grid, PV system owners can benefit from tax relief. Learn more about the "0% VAT rule" here.

With over 1,600 hours of sunshine per year, Berlin offers excellent conditions for solar systems. While it doesn’t match the levels of southern Germany, it’s still a great location for photovoltaic systems.

A well-designed PV system can produce about 900 to 1,100 kilowatt-hours (kWh) of electricity per installed kilowatt-peak (kWp) annually. This is sufficient to cover the electricity needs of an average household and still generate surplus power for the grid.

For example, a 5 kWp system can generate about 4,500 to 5,500 kWh per year, which matches the energy consumption of a typical four-person household.

Yes, solar systems produce electricity even in winter, though less than in the summer months. Efficiency depends on sunlight, so cloudy days naturally yield less power. However, modern solar panels are effective even in diffuse light conditions and can work with snow on them. In January, for example, a well-positioned PV system in Berlin can still achieve about 50-60% of the output it generates on a sunny summer day. For optimal use it's suggested to store energy in summer during over production.

There’s a simple rule of thumb for sizing a photovoltaic system:

Energy demand x 2.5 : 1,000 kWh/kWp

For example, a family consuming 4,000 kWh annually would need a system with a capacity of around 10 kilowatt-peak. For a more detailed calculation, you can quickly fill out our PV configurator online.
