NOVELTY - A Concentrated photovoltaic (PV) solar power stack system includes a solar concentrator (110) assembly (100) that provides high concentration (HC) solar radiation; a HC light pipe (201) having optic fiber bundles that transmit HC solar radiation; a light-to-electricity conversion (LEC) stack (301) assembly (300) having LEC cells enclosed in a housing structure; and a controller and power conditioning assembly (400) for collection, storage and distribution of electricity generated by each LEC cell.    USE - Concentrated PV solar power stack system for generating electricity through direct high concentration sunlight-to-electricity conversion, used in portable and building-integrated applications.    ADVANTAGE - The Concentrated PV solar power stack system can give the consumer a wider selection of system configurations, power outputs and economy.    DETAILED DESCRIPTION - A Concentrated PV solar power stack system comprises:    (A) a solar concentrator (110) assembly (100) that provides HC solar radiation having solar concentrator(s), sun tracking device(s) and combination(s) of spectral and thermal conditioning unit of the HC solar radiation;    (B) a HC light pipe (201) having optic fiber bundles that transmit HC solar radiation and the HC light pipe having two ends, where one end is coupled to solar concentrator assembly;    (C) a LEC stack (301) assembly (300) having LEC cells enclosed in a housing structure, each LEC cell having light-emitting light distribution (LD) panel and direct light-to-electricity generating PV panel(s) positioned adjacent each LD panel, and each of the LD panel having optical inlet port(s) coupled by optical connections to the other end of the HC light pipe; and    (D) a controller and power conditioning assembly (400) for collection, storage and distribution of electricity generated by each LEC cell having direct current (DC) controller(s), battery bank(s), DC-alternating current (AC) inverter(s), control panel(s) and two electrical connections, where one electrical connection is coupled to the interconnect wires connecting each PV panel of each LEC cell and the other electrical connection coupled to load(s).
