The participation of renewable energy sources in the world energy matrix is in evidence in recent years. As a highlight, the Photovoltaic Solar Systems (SFV), present the increase in values of installed capacity and number of installed systems. It contributes to the expansion of these systems actions promoted at the Federal Technological University of Paraná (UTFPR), such as Research and Development (R&D) No. 2866-0464/2017 (Methodology for Analysis, Monitoring and Management of Distributed Generation by Incentive Sources) and the bidding no. 379/2017 for the implementation of the Floating Photovoltaic System for the Generation of Electricity in the Collection of water from the Passaúna dam, coordinated by Companhia de Saneamento do Paraná (Sanepar). The Photovoltaic System Connected to the Grid (SFVCR) of UTFPR was installed on metallic structures fixed to the ground and the Floating Photovoltaic System (SFVF) of Sanepar was installed on floats. The systems have similarities, but for comparative purposes, the behavior of each system was analyzed in an interval of 12 twelve months, evaluating its behavior through the calculation of merit indices such as: performance ratio, capacity factor and energy productivity. The conclusions of the study made it possible to visualize the possible effects of temperature, dirt and inverter sizing factor that can impact the performance ratio of photovoltaic systems. The Floating SFV presented higher annual average values of the FC (Capacity Factor) and YF (Productivity) merit indices. In the analysis of the calculations of the SFV performance rates, lower values of PR (Performance Ratio) of the Floating SFV and Solo SFV were observed, lower than the typical value of 75%, but in the annual average the values were higher in both SFV . Finally, due to the results presented, the possible influences of losses involved that impacted unexpected values in specific cases were discussed.
