    The results include differences in PV costs, battery costs (500 to 1200 EUR/kWh), and varying solar irradiation. For larger rooftop PV systems with battery storage, the battery costs between 600 and 1000 EUR/kWh. For ground-mounted PV with battery storage systems, investment costs for battery storage of 500 to 700 EUR/kWh were assumed.
