Background of this project is a PV roof tile that has a wireless connection for power transfer to the underlying roof lath (batten). This tile has been developed by the company and consists of a roof tile with PV cells, and electronics and one half of a transformer. The other half of the transformer is envisaged to be mounted on the roof lath, which should also contain the auxiliary electronics. The purpose of the project is to design the electronics for both the tile and the auxiliary electronics.
