US 9,136,732 B2 · Distributed energy storage and power quality control in photovoltaic arrays

Abstract

A solar electric system comprises photovoltaic elements having integrated energy storage and control, ideally on each PV-panel. The energy storage media may be primary or secondary cylindrical cells interconnected into a battery and/or an array of capacitors (or super-capacitors) and are accompanied by an electronic control circuit which may perform a variety of functions, including but not limited to: power quality control, load following, pulse powering, active line transient suppression, local sensing, remote reporting, wireless or wired communications allowing two way programmable control through local or remote operation. The operation of the system may yield direct current or with the integration of bidirectional micro-inverters create distributed alternating current generation enhanced with energy storage and control two way energy flows between the solar system and the grid.

Dependent claims

A solar photovoltaic electric system, the system comprising:

a plurality of solar photovoltaic power collectors;
an interconnection with an external load;
a master controller which individually controls a first flow of electric power from a first one of said plurality of solar photovoltaic power collectors to said external load separately from a second flow of electric power from a second one of said plurality of solar photovoltaic power collectors to said external load.

Dependencies are inferred from the claim text.
