h i g h l i g h t sALCA of a mounted 1.8 kWp PV with and without PbA batteries is performed. Main impacts are related to the modules, inverter, and batteries respectively. Both PV systems are environmentally better than centralized electricity systems. Both PV systems are energy sustainable (EPBT = 16.1-16.9 years). Results indicate the implications of rolling PV systems at the regional level.
