A hybrid method is applied to model the operation of solar PV-storage for a typical UK householder, linked with a whole-system power system model to account for long-term energy transitions. Based on results, electricity consumers can cut electricity bills by 28-44% using storage alone, 45-56% with stand-alone solar PV, while 82-88% with PV ...
