Conical roof equipped with solar tiles
The solar tiles were deployed on a conference center in Glücksburg, Germany. In addition to PV, the building also uses solar thermal energy and biomass to cover heat demand. The power generated by the PV array is utilized entirely for self-consumption.
The best PV tech for Internet-of-Things devices
U.S. scientists have evaluated three different PV technologies – GaInP, GaAs, and silicon – for powering wireless temperature sensors. They found that the silicon solar module offers the lowest performance and also suggested its use may be applied to low-demand devices.
