Hybrid operational strategy to use lithium-ion storage in commercial PV arrays Lithium-ion batteries can not only improve self-consumption in commercial PV systems but are also able to efficiently perform peak shaving and price arbitrage, according to an international research group which has proposed a new strategy to calculate the best system configuration in terms of costs and revenue. The scientists specified, however, that the novel strategy may become effective only if storage system prices will drop under $250/kWh.An international research group has defined a hybrid operational strategy to combine commercial PV systems with lithium-ion batteries, from a cost and revenue ...
