Abstract
A roof mountable photovoltaic system, wherein electrical energy is transferred from multiple direct current generating sources to at least one wireless energy receiver device through some separated distance. The system is configured such that electrical energy can be transferred even through an obstruction, such as several layers of roofing material, to the wireless energy receiver device. In some embodiments, there are fewer wireless energy receiver devices than the direct current generating sources. In some embodiments, the wireless energy receiver device can include one or more inductive windings, antennae, or a combination thereof, which can couple with the windings, antennae, or a combination thereof of the wireless transmitter(s) to transfer electrical energy from the transmitters to the one or more receivers without direct electrical or physical connection.
