Performance of grid-tied PV facilities based on real data in Spain: Central inverter versus string system Diez Mediavilla, Montserrat Dieste Velasco, Mª Isabel Rodríguez Amigo, María del Carmen García Calderón, Teófilo Alonso Tristán, Cristina Inverter layout PV system Performance Grid-connected system Two complete years of operation of two grid-tied PV facilities is presented. Energetic and economic performance of both installations has been compared. Located in the same place, the installation of these facilities followed the same construction criteria – PV panels, panel support system and wiring – and the facilities are exposed to the same atmospheric temperature and solar radiation. They differ with regard to their inverter topology used: one facility uses a central inverter and the other a string inverter configuration. The performance of the facilities has been determined using a procedure based on a small number of easily obtained parameters and the knowledge of the analyzed system and its operation mode. Electrical losses have been calculated for both systems and a complete comparison between them has been carried out. The results have shown better performance for distributed system in economic and energetic terms. 2018-01-11T09:13:46Z 2018-01-11T09:13:46Z 2014-10 info:eu-repo/semantics/article 0196-8904 http://hdl.handle.net/10259/4696 10.1016/j.enconman.2014.06.087 eng Energy Conversion and Management. 2014, V. 86, p. 1128-1133 https://doi.org/10.1016/j.enconman.2014.06.087 info:eu-repo/grantAgreement/MINECO/ENE2011-27511 info:eu-repo/grantAgreement/JCyL/BU358A12-2 http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 International Elsevier
