[en] This End of Degree Project (EDP) proposes an alternative to supply the energy consumption derived from the lighting in Building II-I of the Engineering School of Bilbao (ESB). For this purpose, the design and sizing of a photovoltaic installation for self-consumption is proposed, with compensation of surpluses. The project has been carried out with the intention of combining both technological development and sustainability. To this end, the current energy consumption of the luminaire in Building II-I of the ESB has been estimated and different solutions have been analysed to reduce this consumption. Thus, it has been decided to replace the current lighting (which consists of fluorescent lights) with low-consumption LED lights, seeking to make the best use of energy. On this occasion, the new consumption has also been estimated. In view of this new scenario, the options for supplying the luminaire with photovoltaic energy have been analysed. The initial approach was based on an off-grid installation that would completely supply the demand. However, after analysing the viability of this proposal, the system had to be modified, as the space available was not sufficient for an installation with the needed characteristics. Therefore, the option of self-consumption of photovoltaic energy was chosen, designing and sizing an on-grid installation. Once the type of system to be designed has been determined, the necessary resources have been employed to carry out the design process: analysis of the geographical location, choice of the elements of the PV installation, shadow analysis, etc. In addition, the use of various softwares has been fundamental for the development of the project. This work intends to show the options available to carry out sustainable behaviour from the engineering point of view. Likewise, the project is characterized by the clean production of energy and its proximity to the field of energy transition.

[eu] Aurkezten den Gradu Amaierako Lan (GrAL) honek Bilboko Ingeniaritza Eskolako (BIE) II-I Eraikinean luminariaren ondoriozko energia eskaria hornitzeko alternatiba baten proposamena biltzen du. Ildo horretatik, autokontsumoko instalazio fotovoltaiko baten diseinua eta dimentsionamendua garatu da, soberakinen konpentsaziora egokitutakoa. Proiektuaren planteamendua garapen teknologikoa eta iraunkortasuna bateratuz gauzatu nahi izan da. Horrela, gaur egun BIEko II-I Eraikineko luminariak kontsumitzen duen energiaren zenbatespena gauzatu eta kontsumo hori murrizteko irtenbidea bilatu da. Energia aprobetxamendua bilatuz, gaur egun BIEko II I Eraikinean dagoen luminaria (fluoreszenteak) kontsumo baxuko LED moduko argiteriarekin ordezkatzea proposatu eta potentzia kontsumo berria aztertu da. Egoera berri horren aurrean, energia fotovoltaikoaren bidez argindarra hornitzeko aukerak aztertu dira. Hasiera batean, BIEko II-I Eraikineko teilatuan saretik isolatutako instalazio fotovoltaikoa ezartzea planteatu da. Hala ere, proposamen horren bideragarritasuna aztertuta, sistema fotovoltaiko mota moldatu behar izan da; izan ere, eskuragarri dagoen eremuaren ezaugarriek luminariaren energia eskaria erabat asebetetzea eragozten dute. Konponbide bezala sarera konektatutako instalazio fotovoltaikoa diseinatu eta dimentsionatu da, autokontsumora bideratutakoa. Helburu horrekin, lana aurrera eramateko dagozkion informazio-bilketa, kalkulu zein analisiak garatu eta dokumentatu dira: eremu geografikoaren azterketa, PV instalazioaren osagaien aukeraketa eta euren dimentsionamendua, itzalen analisia, eta abar. Diseinu eta dimentsionamenduaren garapenean zenbait software-ek funtsezko papera bete dute. Oro har, ingeniaritzaren alorretik ere jarrera jasangarriak sustatzea posible dela agerian uzten du lan honek. Era berean, energia ekoizteko modalitate garbien eta trantsizio energetikoarekin estuki erlazionatuta dago.
