[en] This document has aimed to develop the design and dimensioning of a photovoltaic solar installation in Los Llanos sports complex in Portugalete. In this case, by analysing the alternatives offered by isolated solar installations and self-consumption solar installations connected to the grid, the most suitable option for the sports complex has been determined. In fact, the design and dimensioning of a self-consumption solar installation has been carried out in which the generated surpluses are sold. To begin with, in the studies of the geographical scope of the sports complex, it has been investigated and selected possible locations of solar panels. The irradiation of the geographical area has also been addressed, confirming the potential of the sports area to have a possible solar installation. Within this work, an analysis of alternatives is proposed to select the main components that make up the photovoltaic solar installation, such as the solar panels or the inverter. Subsequently, the feasibility of the isolated solar installation has been analysed. When analyzing this extreme case and faced with the impossibility of producing the consumption from October to February, the design and dimensioning of a solar installation connected to the grid has been considered. Using SketchUp program, the 3D model of the sports complex has been designed, which has allowed the analysis of shadows. In addition, according to the parameters of behavior of the solar panels in the different times of the year and of input and output of the inverter, the dimensioning of the photovoltaic solar installation has been developed. Thanks to the profitability analysis, if this project were to be translated into reality, a profit of €39,844.16 would be obtained in 25 years. In fact, if a photovoltaic solar installation had been carried out in 2020 in the sports complex of Los Llanos, a profit of €6,744.10 would have been obtained compared to the expenses of that year. Finally, a series of possible risks are posed in the risk analysis, designing a contingency plan to address these problems.

[eu] Dokumentu honek Portugaleteko Los Llanos kirolguneko eguzki-instalazio fotovoltaiko baten diseinua eta dimentsionamendua garatzea izan du helburu. Kasu honetan, isolatutako eguzki-instalazioek eta sarera konektatutako autokontsumorako eguzki-instalazioek eskainitako alternatibak aztertuz kirolgunerako aukerarik egokiena zehaztu da. Izan ere, autokontsumorako eguzki-instalazio baten diseinua eta dimentsionamendua aurrera eraman da, non sorturiko soberakinak saltzen diren. Hasteko, kirolgunearen eremu geografikoaren azterlanetan eguzki-panelen kokapen posibleak ikertu eta aukeratu dira. Baita eremu geografikoaren irradiazioari erreparatu zaio ere, kirolguneak eguzki-instalazio posible bat edukitzeko potentziala berretsiz. Lan honen barruan eguzki-instalazio fotovoltaikoa osatzen duten osagai nagusiak aukeratzeko alternatiben analisia planteatu da, eguzki-panelak edota inbertsorea aukeratzeko hala nola. Ondoren, isolatutako eguzki-instalazioaren bideragarritasuna aztertu da. Muturreko kasu hau aztertzerakoan eta urritik otsailerako kontsumoa ekoiztea ezinezkoa dela ikusita, sarera konektatutako eguzki-instalazio baten diseinua eta dimentsionamendua planteatu da. SketchUp programa erabilita, kirolgunearen 3D eredua diseinatu da eta horri esker itzalen analisia egitea posible izan da. Gainera, eguzki-panelek urteko garai desberdinetan duten portaera eta inbertsorearen sarrera-irteera parametroen arabera, eguzki-instalazio fotovoltaikoaren dimentsionamendua garatu da. Errentagarritasunaren analisiari esker, proiektu hau errealitatera eramango balitz 25 urtetan 39.844,16 €-ko irabazia lortuko litzateke. Izatez, 2020. urtean Los Llanoseko kirolgunean eguzki-instalazio fotovoltaikoa egin izan balitz, 6.744,10 €-ko irabazia lortuko zen urte horretako gastuekin alderatuta. Bukatzeko, arriskuen analisian eman daitezkeen arrisku posible batzuk planteatu dira, arazo hauei aurre egiteko kontingentzia-plan bat diseinatuz.
