IMPACT OF BUILDING PARAMETERS ON ECONOMICS OF PHOTOVOLTAIC SYSTEMS

Relavantne raziskave kažejo, da fotovoltaika postaja konkurenčna preostalim konvencionalnim virom, da bo v prihodnosti bistveno vplivala na proizvodnjo energije v Evropi ter pomembno vpliva na zamnjšanje emisij toplogrednih plinov. V teoretičnem delu so zajete tehnične zasnove in delovanje fotovoltaičnih elektrarn. Pri tehničnih zasnovah so opisani materiali in njihove lastnosti, obremenitve ter načrtovanje in montaža fotonapetostnih sistemov. V nadaljevanju spoznamo osnove fotovoltaike od sončnega sevanja do zgradbe in tipov sončnih celic. Teoretični del diplomskega dela še sestavlja ekonomiko projektnih odločitev za investicije v potencialne projekte fotonapetosnih sistemov, kje so opisane različne metode izračunov za projektne odločitve. Po teoretičnem delu sledi empirični del. V tem delu je opisan projekt Vulkanland ter izbira komponent fotonapetostnega sistema. Za obdobje 25 let so podani podatki proizvedene energije po letih ter prejemki in izdatki, ki predstavljajo denarni tok investicije. V zadnjem koraku izberemo metodo neto sedanje vrednosti za izračun ekonomske upravičenosti. Ugotovili smo, da je fotovoltaika primerna tako z okoljevarstvenega vidika kot z vidika ekonomske upravičenosti.Relevant researches show that photovoltaic is becoming competitive to other conventional sourcesit is also going to fundamentally influence power production in Europe in the future and it is going to substantially lower green gas emissions. The theory section of my work is mainly comprised of technical design and the workings of photovoltaic power plants. The technical design part describes materials and their properties, charging, planning and the assembly of photovoltaic systems. Next we learn about the basics of photovoltaic from solar radiation to its construction and different solar cell types. The theory part of my work also includes the economic reason for investments in potential projects of photovoltaic systems, where different methods of calculations for project decisions have been covered. The theory part of my work is followed by an empirical part. In this section I have described "Project Vulkanland" and also the chosen components of the photovoltaic system. A 25-year power output data is provided in annual sections as are all expenses and income that represent the financial flow of the investment. In the last part we choose the net current value method for an economic justification summary. We have found out that photovoltaic is appropriate from the environmental point of view and from point of view of economical justification
