The topic of this paper is the analysis of the possibility of using solar panels in hotels in Zagreb. The use of electric consumption for solar panels was first analysed, and then compared. A large number of hours of sunshine makes it convenient to use solar panels, and it also brings great benefits. There are many advantages of such use, but the protection and preservation of the environment should certainly be emphasized. The reason for choosing the final paper on this topic was the fact that Zagreb does not have hotels with solar panels. Moreover, there was a desire to explore the advantages and disadvantages of solar panels, and the technical conditions for the installation of the same. The paper first introduces to the reader the basic concepts needed to understand the topic, it then analyses the possibilities of using solar panels in hotels, and it finally offers suggestions, approaches and justification for installing solar panels in the existing hotels, new buildings and other types of accommodation. Zagreb has great potential. However, technical and economic conditions need to be met as well.
