Abstract
A system of solar roof shingles and underlayment with wireless power transfer between the solar roof shingles and the underlayment is disclosed. Each roof shingle has a solar collector array coupled to a wireless resonator. The solar collector array establishes a voltage in response to exposure to sunlight and the wireless resonator converts the voltage to a transmittable electromagnetic signal. The signal is transmitted to resonant devices embedded in the underlayment beneath the shingles The resonant devices may be resonant capture devices that convert the received electromagnetic signal back to a usable voltage, or they may be wireless repeaters that retransmit the electromagnetic signal to remote resonant capture devices, which then convert it to a voltage. This voltage is placed on an electrical grid and made available at a remote location for use, storage, or placement on the public electrical grid.
