This invention relates to a photovoltaic (PV) unit adapted to provide wireless power transfer output comprising one or more photovoltaic cells that generate electrical output, and at least one wireless power transfer transmitter coupled to transfer the electrical output via wireless power transfer. Such a PV unit can be provided in combination with a roofing, cladding or siding module. Such a module comprises an underlapping region and an exposed region of an adjacent module when installed on a building surface; and an outer surface and an under surface, wherein the under surface of the underlapping region is profiled to define a pathway for air flow between the module and the building surface. |
