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. 000056813 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/ENE2013-48517-C2-1-R 000056813 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000056813 590__ $$a2.262$$b2016 000056813 591__ $$aENERGY & FUELS$$b45 / 92 = 0.489$$c2016$$dQ2$$eT2 000056813 592__ $$a0.662$$b2016 000056813 593__ $$aElectrical and Electronic Engineering$$c2016$$dQ1 000056813 593__ $$aRenewable Energy, Sustainability and the Environment$$c2016$$dQ2 000056813 593__ $$aEnergy Engineering and Power Technology$$c2016$$dQ2 000056813 593__ $$aControl and Optimization$$c2016$$dQ2 000056813 593__ $$aEnergy (miscellaneous)$$c2016$$dQ2 000056813 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000056813 700__ $$0(orcid)0000-0002-1490-6423$$aDufo-López, R.$$uUniversidad de Zaragoza 000056813 700__ $$0(orcid)0000-0003-2813-1240$$aBernal-Agustín, J.L.$$uUniversidad de Zaragoza 000056813 7102_ $$15009$$2535$$aUniversidad de Zaragoza$$bDpto.
