Always make the best choice for your solar power project

The challenge of generating more renewable energy and achieving energy efficiency

Realize your solar power project and invest in the future of your company. With a solar energy subsidy (SDE ++) you can reduce energy costs, achieve a positive financial return and contribute to the local energy transition.


What are the options on my roof?

What requirements must the installation meet for insurance? Is my connection with the grid operator large enough? Are my construction and roof covering suitable for solar panels?


What is the return of solar panels?

What are the investment costs and how do I earn them back? Can I apply for a subsidy? How can I make agreements with my tenant about purchasing the electricity?


What else do I have to take into account?

What about the energy tax? What about home insurance? How do I deal with O&M and contract management?

Together we make solar energy the norm.
