Here you can find frequently asked questions and answers on the topic of renewable energy for business customers in Berlin.
Do you also offer storage solutions for energy from renewable sources?
Yes, we offer various storage solutions, including battery storage for photovoltaic systems, to make optimal use of self-generated electricity and increase grid independence.
How energy-efficient are heat pumps in winter?
Modern heat pumps are very efficient even at low outdoor temperatures. They can extract heat from the environment even in frosty conditions and are therefore a reliable energy source throughout winter.
How do you integrate renewable energy systems into existing building infrastructure?
Thanks to our expertise and modern technology, we can seamlessly integrate renewable energy systems into existing infrastructure – whether in new buildings or when modernising older properties.
What maintenance and care do such systems require?
Like all technical installations, renewable energy systems also require regular maintenance. The exact requirements vary depending on the technology, but we offer comprehensive maintenance contracts to ensure a long service life and optimal performance.
How eco-friendly are your renewable energy systems really?
The systems are designed to significantly reduce CO₂ emissions. The exact savings depend on the system in question, but we prioritise maximum efficiency and sustainability.
What government subsidies are available for renewable energies in large-scale projects?
There is a wide range of subsidy programmes at both state and federal level. We are happy to advise you in detail on the current options and provide support with applications.
How profitable are investments in renewable energy systems for large-scale projects?
Profitability depends on various factors, including the size of the project and the chosen technology. In general, such systems often pay for themselves within a few years, not least thanks to government subsidies and saved energy costs.
What renewable energy sources do you offer for large-scale projects?
We offer a wide range of solutions, including heat pumps, photovoltaic systems, fuel cell heating & CHP systems, to name just a few.
