The aim of the study was to evaluate the potential of solar plots in Łazy village, located in the municipality of Jerzmanowice-Przeginia, in terms of suitability for the construction of solar power plants of 4 different sizes: large, medium, small and micro. As a part of the study, the modelling of solar radiation and spatial analyses were performed, using the ArcMap 10.3.1 and QGIS 2.8.1. Wien software. The entire test area was divided into 4 classes, according to the inso- lation potential. The end result consists of maps showing the land with best prospects for solar investments. We have also presented the evaluation of the possibility for obtaining solar energy via photovoltaic panels located on the roofs. Within the village of Łazy, we have identified 63% of the parcels, of which at least 80% enjoy good or very good solar conditions, that is to say, during the year, the solar radiation for these places exceeds 960 kWh · m–2 .
