Method for alternating conversion solar power
Different systems to achieve solar power conversion are provided in at least three different general aspects, with circuitry that can be used to harvest maximum power from a solar source ( 1 ) or strings of panels ( 11 ) for DC or AC use, perhaps for transfer to a power grid ( 10 ) three aspects can exist perhaps independently and relate to: 1) electrical power conversion in a multimodal manner, 2) alternating between differing processes such as by an alternative mode photovoltaic power converter functionality control ( 27 ), and 3) systems that can achieve efficiencies in conversion that are extraordinarily high compared to traditional through substantially power isomorphic photovoltaic DC-DC power conversion capability that can achieve 99.2% efficiency or even only wire transmission losses. Switchmode impedance conversion circuits may have pairs of photovoltaic power series switch elements ( 24 ) and pairs of photovoltaic power shunt switch elements ( 25 ).
