PHOTOVOLTAIC ELECTRIC UTILITY ON THE ROOF OF A SINGLE FAMILY HOUSE - PROFITABLE INVESTMENT OR MODERN TREND

Diplomska naloga opisuje problem na področju pridobivanja energija. V svetu je še vedno prisotno preveliko zanašanje na fosilna goriva, kar ima za posledico onesnaženje ozračja. Diplomska naloga predstavi smotrnost postavitve fotovoltaične elektrarne na streho enodružinske hiše. Fotovoltaika se smatra kot ena glavnih alternativ sedanjemu načinu pridobivanju energije. Vendar trenutno je še premalo razvita in razširjena, da bi se lahko kosala z ostalimi prevladujočimi načini pridobivanja. Se pa napoveduje fotovoltaiki svetla prihodnost, zato je potrebno razmišljat o podobnih projektih tudi na domačih enodružinskih hišah. Kot pokaže izračun, investicija v fotovoltaiko ni investicija z katero bi se človek obogatil, je pa zelo varna naložba z zagotovljenim končnim dobičkom. Skozi diplomsko nalogo je predstavljen celoten potek, od načrtovanja do izvedbe fotovoltaične elektrarne. Pri praktičnem primeru je napravljen izračun in potem primerjava pri dveh različnih tipih pritrjevanja. Podatki v diplomski nalogi so resnični, pridobljeni pri slovenskih in tujih podjetjih, ki se ukvarjajo z fotovoltaiko. Praktični primer je zasnovan na predpostavki, da sem jaz investitor na lastnem objektu z izgradnjo fotovoltaične elektrarne v lastni izvedbi in ne v izvedbi na »ključ«. V diplomski nalogi so odgovori na ključna vprašanja fotovoltaike: začetna investicija, doba amortizacije, dobiček. V zaključku sem dodal moje izkušnje na področju fotovoltaike, z katero se ukvarjam v podjetju HOSEKRA d.o.o. in moje razmišljanje in razmišljanje strank z katerimi imam vsakodnevni kontakt.The aim of this graduate work is to research some problems, which are connected with use of solar energy. Nowadays, the use of fossil fuels is still world-wide and this raise a lot of enviromental concerns. My graduate work introduces purpose of providing an photovoltaic installations on a rooftop of a single-family detached house. Photvoltaic is nowadays concern as one of the main alternatives to different ways of using energy. Still, at the moment this way of using energy is not developed enough to compete with others, which are spread more worldwide. In the future we can assume that photovoltaic will become more important so we can think to include it in processes of building a single-family detached houses. As we can see further, the investigation in photovoltaic energy source is not highly profitable but is still a safe investment with a small long-term assure profit. In my graduate work there is a presentation of the whole progress - from planning to realization of rooftop photovoltaic installation. A description of practical case is based on calculations and comparition between two different types of fixing the photovoltaic installation. This data aquisition are linked with actual calculations taken from Slovene and foreign companies which are dealing with photovoltaic. I went on the assumption that I\u27m the investor in building my own house which include rooftop photovoltaic installation as my own investition and not as a part of the fixed »on the key« realization of building the house. Through this calculations I tried to find key answers in the photovoltaic field which are: investment, payback period, profit. I finalized my work with adding own considerations of photovoltaic which are based on experince which I gained in the company HOSEKRA d. o. o. I described few considerations of customers of the company who I\u27ve been dealing with, as well
