The results show that PV generation can be self-consumed without the battery when R pv is less than 45 %. The battery capacity demand then shows an approximately linear growth as R pv increases from 45 % to 70 %. For R pv above 70 %, the battery capacity demand explodes, and the battery utilization degree significantly declines.
