<p>The article presents options for the layout of a hotel building on a plot of land, modelling the efficiency of solar modules on the roof. At the initial stage of the project, when there are no restrictions from territorial planning documents, it is possible to select the optimal roof structure as well as the building orientation in relation to the cardinal points to maximize the exploitation of the power of solar modules installed on the roof. The modelling is performed using the <em>PVsyst</em> universal software for the design, analysis and optimization of solar power plants. After analysing the building models in four cardinal directions, the chosen position of the building model is the roof slope with solar modules turned to the southwest (according to the results of the two most efficient directions)&nbsp;– the rotation angle is 39° clockwise from the south. Solar modules oriented in the southwest direction generate 19,166 kWh/year, and after considering the tree shadows&nbsp;– 19,029 kWh/year (a difference of about 0.7%). Compared to the most efficient southern direction, the difference is 3%.</p>
