Service and maintenance

We are also on hand to help you after the installation. By professionally managing the system, we will make sure that your system continues to operate at its optimal level. Year in, year out.


Various subsidies and tax incentives have made investing in solar panels very interesting for companies and organisations. A win-win-win situation; it is financially attractive, you save on your monthly energy costs, and you contribute to a better environment by generating sustainable energy.


You can choose to either fully or partially finance your solar power system. Thanks to our extensive network and experience, we are able to draw up the optimum financing plan for you. You remain the owner of your solar power system and get to keep the financial returns for yourself.
