This dissertation presents the combination of an electrical and thermal model to represent the characteristics of the photovoltaic module floating in water. Based on the proposed model a MATLAB / Simulink software simulation is made and validated with data obtained through a experiment performed. Two experiments were conducted in the UFC Alternative Energy Laboratory in order to validate the model proposed by the use of two distinct manufacturing photovoltaic modules, a monocrystalline produced by Azur Solar GmbH model TSM 160M and a polycrystalline produced by Solartec model KS20T. The model proposed was satisfactory compared the model results with measured data, which is irradiance, temperature front, rear and IV characteristic curve of the PV module. The irradiance is obtained by a pyranometer LP02 model Hukseflux manufactured by Thermal Sensor, temperatures were measured with temperature sensors type thermo EN 100 and the characteristic curves were obtained by tracer curve mini-KLA, manufactured by Ingenieurbüro. The monocrystalline module errors were lower than 4% for short-circuit current values, open circuit voltage and maximum power point. To reduce the error the electric model initially proposed was changed at the point of maximum power and were obtained errors lower than 2% for the short-circuit current values, open circuit voltage and maximum power point. The polycrystalline module showed errors lower than 10% for the short-circuit current values, open circuit voltage and maximum power point. The polycrystalline module floating in water performance was compared to the conventional use (installed on the ground), being recorded a cell temperature difference at any given time of day to 29 °C between the two applications; as a consequence, better efficiency was obtained floating on the water module with power gains of up to 17% compared to conventional usage.
