- A solar photovoltaic energy flywheel storage and conversion system for residential applications was designed, built and tested. Performance and efficiency measurements were conducted on the system, which utilizes low-loss magnetic bearings, maximum-power-point tracking of the photovoltaic array, integrated permanent magnet motor-generator, and output power-conditioning sections of either the stand-alone cycloconverter or utility interactive inverter type. The overall in-out electrical storage efficiency of the flywheel system was measured along with the power transfer efficiencies of the individual components and the system spin-down tare losses. A round-trip storage efficiency of 82% in the utility interactive mode and 74% in the stand-alone mode was found. This compares favorably with systems involving batteries and an inverter, which typically exhibit a round trip efficiency less than 70%.
