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. 0196-8904 http://hdl.handle.net/10259/4696 10.1016/j.enconman.2014.06.087 Inverter layout PV system Performance Grid-connected system Performance of grid-tied PV facilities based on real data in Spain: Central inverter versus string system
