This bachelor thesis deals with the comparison of different configurations of photovoltaic systems suitable for installation on a family house. In the introductory part, a research of different components of PV systems such as solar panels, inverters, battery storage is carried out. Attention is also given to the possibilities of connecting PV systems and also the use of the subsidy program. Subsequently, two specific configurations are selected and subjected to a technical and economic comparison. The PVSOL software was used to design the configurations. The main objective of the work is to assess which of the options offers a more efficient use of solar energy with respect to investment and operating costs. Finally, the results are summarized and recommendations for the selection of the configuration in terms of return on investment and long-term sustainability are presented.
