Comparison of Systems for Solar Electricity Production

V nalogi smo raziskali možnosti izrabe energije Sonca za proizvodnjo električne energije v majhnih postrojih, ki so sestavni – integralni del objektov. Z uporabo podatkov in metod iz literature smo določili potencial sončnega sevanja za poljubno mikrolokacijo z upoštevanjem geografskih, topoloških, in meteoroloških pogojev. Primerjali smo dve tehnologiji za pretvorbo sončne energije v električno energijo: fotonapetostne pretvornike in termični solarni sistem z uporabo krožnega procesa. Na podlagi vrednotenja skupnega energijskega izkoristka ter tehnoloških značilnosti obeh sistemov smo ugotovili, da je fotonapetostni sistem boljši, kar odraža tudi praksa.In this thesis we asses the possibility of using the energy of the Sun for the production of electricity in small-scale systems, which are integrated into buildings. With the use of data and methods from literature we defined the energy potential of solar radiation for a desired microlocation, taking into account the influence of geographical, topological and meteorological factors. We compared two different technologies for converting solar radiation into electricity: photovoltaic converters and a thermal solar system that utilizes a thermodynamic cycle. Upon evaluating the effective energy efficiency and technological characteristics we found that photovoltaics are superior to the thermal solar system for small-scale utilization, whics is also confirmed in practice
