PHOTOVOLTAIC GENERATION POTENTIALS ON BUILDING ROOFS IN A HOTEL FACILITY.

In the present investigation, the calculation of the potentialities of photovoltaic generation is presented from the use of the roof surfaces of the buildings of the Hotel Punta la Cueva, Cienfuegos. For this, an energy study was carried out at the facility with the aim of identifying the demand that is intended to be satisfied, and the constructive survey of the shade-free buildings that can be used for the assembly of photovoltaic panels was carried out, considering the dimensions, orientation and slope of its roofs, in addition, the specific meteorological information of the territory was obtained, necessary for the generation calculations and its inclusion in the specialized PVsyst software. The simulation with the PVsyst showed that in the hotel there is an available building roof area of 2 057.78 m2, an area where it is possible to install a total of 891 photovoltaic modules of the DSM-270 model, with a generation capacity of 240.33 kWp and an actual annual generation of 363.96 MWh/year. This photovoltaic installation is capable of fully covering the hotel's energy demand during daytime hours and delivering an average of 13.75 MWh/month to the National Electric System (SEN).
