Batteries are used for price arbitrage, being charged with the photovoltaic (PV) generation during hours of low electricity price and discharged during hours of high price. The correct estimation of the battery lifetime has great importance in the calculation of the net present value, to do this advanced models for estimating the Li-ion battery lifetime (considering cycle and calendar ageing) are used. With present components costs, considering the Spanish SPOT price of 2021 with an expected increase of 1% annual, the AC coupled utility-scale PV-plusbattery isn’t economically viable comparing to the PV-only system. If electricity hourly price was multiplied by two, in certain cases adding battery to the PV system would be profitable. info:eu-repo/grantAgreement/ES/AEI/PID2021-123172OB-I00 info:eu-repo/semantics/openAccess by-nc-nd http://creativecommons.org/licenses/by-nc-nd/3.0/es/ 0.152 2023 Electrical and Electronic Engineering 2023 Q4 Renewable Energy, Sustainability and the Environment 2023 Q4 Energy Engineering and Power Technology 2023 Q4 0.7 2023 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Lujano-Rojas, Juan M.
