INVESTMENT ANALYSIS IN PHOTOVOLTAIC SYSTEM DEPENDING ON DIFFERENT SOLAR MODULES

Diplomska naloga predstavlja izračun investiciji v postavitev sončne elektrarne, ki jo bomo implementirali z različnimi vrstami sončnih modulov. Omejili se bomo na mikro sončne elektrarne, kar pomeni, da inštalirana moč sončne elektrarne ne presega 50 kWp. Izgradnja sončne elektrarne lahko predstavlja velik finančni strošek, zato bomo v diplomski nalogi ocenili upravičenost investicije v postavitev sončne elektrarne pri implementaciji z različnimi vrstami sončnih modulov. Tako bomo med seboj primerjali sončne elektrarne z monokristalnimi Si, polikristalnimi Si, amorfnimi Si, tankoplastnimi GaAs in CdTe sončnimi moduli. V tehničnem delu so predstavljene osnove delovanja sončnih celic in tehnologije obravnavanih sončnih modulov. V ekonomskem delu so predstavljeni ekonomski kazalci in različne metode izračuna investicije. Narejena je analiza izračuna investicije ekonomske upravičenosti projekta in doba vračanja investicije.The diploma thesis presents the calculation of the investment for installing a solar power plant, which will be implemented with various types of solar modules. The focus will be on micro solar power plant, which means that the installed power capacity of solar power plant does not exceed 50 kWp. The installation of solar power plant can represent a significant financial cost. In this way the eligibility of investment will be assessed by implementation of different types of solar modules. The solar power plants with mono-crystalline Si, poly-crystalline Si, amorphous Si, thin film GaAs and CdTe solar modules will be compared. In the technical part the basic operation of solar cells and technology of solar modules are presented. In the economic part the economic indicators and the different methods of calculating investment are presented. The analysis of the investment calculation of the economic viability in the project and payback period of the investment is shown
