Abstract

Described herein are improved configurations for a wireless power transfer involving photovoltaic panels. Described are methods and designs that use electric energy from a photovoltaic module to energize at least one wireless energy source to produce an oscillating magnetic field for wireless energy transfer. The source may be configured and tuned to present an impedance to a photovoltaic module wherein said impedance enables substantial extraction of energy from said photovoltaic module.
