Hielke has a passion for producing and storing energy for now and the future.

He works from Berlin and Assen. Since childhood he has been an entrepreneur but for about five years he has focused on starting a factory for the best solar panel solution on the market in combination with solid wood houses. Because Hielke is a master at connecting people and companies, opening doors and making new contacts, he has now found the right solution with the right company and with the best engineers and inventors. 

By working with these people now and in the future, and with the right financial partners, who have a drive to advance renewable energy and bring it to market. 

The best of all will ultimately be to produce a German/European product, cut ties with Asia as much as possible and put the industry where it belongs, on European soil.
