[ca] Per fer el treball es partirà per un primer anàlisi dels marcs reguladors que promocionen la generació de les energies renovables, d'aquesta anàlisi s'extreu que existeixen dos marcs reguladors. El Reial Decret 413/1014 i el Reial Decret 960/2020. Els quals tenien licitació al respecte, Reial Decret 413/2014 i Reial Decret 960/2020. Una vegada analitzats els marcs reguladors. Es fa una anàlisi dels resultats de la licitació on es contemplen les empreses adjudicatàries. Posteriorment, es realitzen bases de dades (BBDD) amb la informació recollida d'una recerca exhaustiva de cara a analitzar els projectes de cara a extreure les instal·lacions tipus i obtenir les primeres conclusions. A continuació amb les plantes tipus és fer un model determinista per aconseguir resultats físics i aconseguir el comportament de potència i generació on posteriorment es farà una model estocàstica de cara a extreure les conclusions definitives. Una vegada fet l'anàlisi es pot concloure a grans trets que no hi ha canvis significatius en el disseny. S'ha pogut comprovar que la majoria de plantes solars de 2017 eren dissenyades amb seguiment solar a un eix amb orientació N-S i seguiment E-O. Amb la modalització s'ha pogut observar les variacions de generació energètica que representa el seguiment solar i com influeixen els paràmetres de les plantes com la irradiació i la temperatura.

[en] This project is based on the public bids held in Spain under Real Decreto 413/2014 and Real Decreto 960/2020. These bids were subject to regulatory frameworks in which different aspects were valued. This creates an interest in analyzing the behavior of the promoters of each one of these bids. In order to carry out this analysis I will conduct a thorough work of investigation of the companies that won the bids to extract information about their energy plants and the features that allow the analysis. I will extract all kind of data: location, investment, technical data, etc. Later I will perform a physical deterministic modeling work which will allow me to extract data of solar plants of which I have enough technical data to carry out the analysis. After that, I will undertake another stochastic modeling work that allows me to monitor the energetic behavior of the photovoltaic solar power plants. Once the analysis of the bids is complete, we can broadly conclude that there are no significant changes in the design, but for a few exceptions. I was able to verify that the great majority of solar power plants in 2017 were designed with single axis sun tracking oriented N-S and E-W tracking, except for the 7%, that have a fixed structure, and a 5% that have two-axis tracking. Whereas the ones tendered in 2021, even though not all the information is available because of its recent bidding, are designed with single axis tracking except for one unit in which the installation power is lower than that of the preassignment, which could be an incentive to install two-axis tracking in order to increase the energetic production. It is worth noting that the Real Decreto 960/2020 sets a maximum number of hours of injection, which makes the installations to stop working when they reach the limit, because they stop receiving the sales amount established in energy; this could be the reason for not using the two-axis tracking, but we don't have enough information to confirm that. It is also relevant to note the evolution of the solar panel power and its peak power.
