Techno-economic analysis of PV-battery systems in Switzerland

This paper presents a techno-economic optimization model to analyze the economic viability of photovoltaic battery (PVB) system for different residential customer groups in Switzerland clustered based on their annual electricity consumption, rooftop size, irradiation and location. The simulations static investment are carried out years 2020–2050 comprehensive sensitivity analysis is conducted investigate impacts individual parameters such as costs, load profiles, prices tariffs, etc. Results show that while combining (PV) with batteries already results better net present values than PV alone some today, payback periods fluctuate between 2020 2035 due mixed effects policy changes, costs price developments. optimal sizes increase over time 2050 mostly limited by size. PVB investments varies most attractive (i.e., has shortest period) accessible higher demand. In addition, decisions highly sensitive periods, future tariff
