Sizing of a grid-connected photovoltaic system for yearly net self-sufficient energy supply

Abstract

The objective of this thesis is the generation of electricity from solar energy for yearly net self-sufficient supply of a household with electricity. Therefore, it is the aim to design a solar photovoltaic installation connected to grid with a consumption of 5000 kWh per year. The main objective is to study and compare two aforementioned PV plants located two places, were the weather conditions and solar irradiation are completely different: one location is Maribor, in Slovenia, and the other is Murcia, in the south of Spain. The thesis defines the technical conditions of the installation from solar radiation recorded in the chosen locations. Like points to emphasize in the thesis, may be considered data obtained from PVSYST to size the installation program. It is important to carry out these projects if we want to achieve a sustainable energy supply. They should be aligned with policies that promote efficiency and energy saving. However, further investigations to improve the utilization of solar energy and other renewable energies should be performed as well.
