Analysis of photovoltaic self-consumption systems 2016 Access copy available to the general public Unrestricted Components and installation prices could make the self-consumption of solar photovoltaic (PV) systems competitive. In this paper, we explore different self-consumption options, off-grid PV systems (with back-up generator and/or batteries), and grid-connected PV systems under net-metering policies. The calculation of the net present cost (NPC) reveals that the grid-connected PV-only case (for the net-metering scheme) is the most attractive from the technical and financial points of view, with a levelised cost of energy less than 0.1 €/kWh. Off-grid PV + Diesel + Batteries has a higher cost, around two or three times the grid-connected PV-only under net metering. Additionally, the off-grid PV + Diesel is less attractive from a financial point of view, which has a cost of around 10 times the PV-only under net metering. In addition, the values of life cycle CO2 emissions in each of the cases studied have been compared, and we have concluded that although the off-grid PV + Diesel + Batteries system presents lower CO2 emissions than the PV-only system, the existence of batteries does not allow one to affirm that the PV + Diesel + Batteries system is the best from an environmental point of view. info:eu-repo/grantAgreement/ES/MINECO/ENE2013-48517-C2-1-R info:eu-repo/semantics/openAccess by http://creativecommons.org/licenses/by/3.0/es/ 2.262 2016 ENERGY & FUELS 45 / 92 = 0.489 2016 Q2 T2 0.662 2016 Electrical and Electronic Engineering 2016 Q1 Renewable Energy, Sustainability and the Environment 2016 Q2 Energy Engineering and Power Technology 2016 Q2 Control and Optimization 2016 Q2 Energy (miscellaneous) 2016 Q2 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion (orcid)0000-0002-1490-6423 Dufo-López, R.
