Cost-Benefit Analysis of Househiold PV systems

Glavni cilj završog rada je detaljan opis realizacije projekta sunčane elektrane gdje su potpuno opisane ključne komponente fotonaponskih modula s električnim parametrima, te radnim i temperaturnim svojstvima i parametri izmjenjivača s istosmjernom i izmjeničnom stranom. U sklopu rada opisane su tehničke karakteristike sunčane elektrane koje su izračunate preko matematičkog modela. Prikazan je postupak vrijednosti investicije elektrane, komponenti, cijene troškova te izračun otkupa električne energije u Rebuplici Hrvatskoj. Na primjeru obiteljske kuće analizirana je isplativost sunčane elektrane za pojedine mjesece u godini.The main objective of this thesis is to provide a detailed description of the implementation of a solar power plant project, including a comprehensive overview of key components of photovoltaic modules with their electrical parameters, as well as their operational and temperature characteristics, and the parameters of the inverter with its DC and AC sides. The technical characteristics of the solar power plant are described within the thesis, and they are calculated using a mathematical model. The process of determining the investment value of the power plant, components, cost prices, and the calculation of electricity purchase in the Republic of Croatia are presented. The profitability of the solar power plant for specific months of the year is analyzed using the example of a residential house
