Conclusion of contract with RheinEnergie

The close contact with RheinEnergie since 2015 culminates in an extensive partnership with the conclusion of a cooperation and technology purchase agreement for our innovation, the solar roof tile with roof system. With this agreement RheinEnergie secures the patent rights of our innovation and at the same time invests very extensively in our further development of these technologies up to series production. The next milestone in the cooperation is to build and operate a model roof by the middle of the year. In addition, it is intended to set up a joint venture company for the production and sale of the solar roof tiles and accessories in the future.


We are delighted that RheinEnergie sees the great potential of our innovation and the considerable advantages over conventional solutions and would like to launch this forward-looking product together with us.
