In this study, an experimental study was conducted to reduce the efficiency loss caused by the increase in temperature in photovoltaic (PV) modules that operate independent of the grid. The experiment was carried out by using a pair of polycrystalline and a pair of monocrystalline PV modules. A reference/control module was selected from each type of PV modules and these control modules were added to the system as traditional PV modules. Heat pipe and phase changing material were applied to the back surface of other PV modules. Figure A. Module Temperature Change Due to Solar RadiationPurpose: In this study, we examined how the change of PV module temperature affects panel output parameters. Instantaneous changes in the module temperature were reduced by using heat pipe and PCM. The modules were kept at a low operating temperature with the methods applied, allowing them to operate at high efficiency.Theory and Methods: The average temperature of PV modules was lowered using the heat pipe and phase-changing substance. One module from the monocrystalline and One module from the polycrystalline modules were placed on the measurement table as reference modules. For the other 2 modules, the double layer was fixed to the back surface of the panel by placing the heat pipe between the macro capsules. The heat pipe was manufactured from copper pipe using the Utype method. FDM was fixed by placing copper tubes between the macro capsules. The experiments were conducted under the conditions of Kayseri province. Results:The temperature measured on the surface of the reference/control module was 30-80ᵒC during the day, while the temperature ranged between 30-40ᵒC in the experimental modules with phase changing substance. We found that the performance loss caused by increase in surface temperature in reference/control modules reaches up to 20%. Whereas, the performance loss in the experimental modules is only as high as 1% under the same conditions. Conclusion:Module temperature tends to increase due to solar radiation and environmental conditions. Although the module temperature tends to increase, the heat pipe and FDM balance the temperature. They subsequently lower the mean temperature, thus, reducing the loss of performance caused by the increased temperature.

One of the parameters affecting the efficiency of photovoltaic (PV) modules and PV systems is the temperature. The factors that increase the temperature in PV modules cause loss of efficiency. In this study, experiments have been conducted with the aim of re ducing the module temperature. For this purpose, four polycrystalline and four monocrystalline PV modules, all with the same features, were used. A pair of polycrystalline and monocrystalline modules were used as reference modules. The aim of this study is to reduce the operating temperature of the modules, while also decreasing the transient temperature fluctuations in the system, in order to prevent the loss of efficiency. For this reason, current, voltage and power values of PV modules have been examined and the relationship between these values and module temperature has been explained. As a result, temperature values were measured at 30-80°C in reference modules, 30-50°C in heat pipe modules, 30-37°C in modules using heat pipes and phase-changing material, and 30-66°C in modules using phase-changing material with flexible surfaces. If the PV module operating temperature is increased by 35°C, the module efficiency decreases by 10%. Heat pipe and PCM balance the temperature in PV/T/PCM monocrystalline and polycrystalline modules. In PV/T/PCM modules, efficiency loss caused by temperature increase is 1%. In addition, electrical energy is produced from the heat accumulated on the surface of the PV module by means of Thermoelectric Generator (TEG). When the temperature difference between the surfaces is 15°C, the naturally cooled TE provides 0.45V energy output, while the forced-cooled TEG provides 0.97V energy output. As the temperature gap between the surfaces increases, the voltage and current values of the TEG also increase. Briefly, TEG’s power values increase up to 5W depending on the temperature gap between surfaces.

In this study, a real-time power estimation of a 250Wp solar panel is performed by using a commercial product SIS01-TC-T PV reference module and STM development board. Power estimation was carried out with Adaptive Neuro-Fuzzy Inference System (ANFIS). During the training process, the actual values of the Photo Voltaic (PV) panel with a 250Wp power were used. ANFIS training was accomplished with the hybrid learning algorithm. The power estimation process can be used as a reference power for various applications. The estimated power value can be used in real-time power monitoring for remote monitoring systems or optimum angle control applications for solar tracking mechanisms. It can also be used as a reference value for hybrid Maximum Power Point Tracking (MPPT) control applications or Proportional, Integral, and Derivative (PID) control. In addition, with this reference power value, the Pulse Width Modulation (PWM) signal required by various power electronics stages can be generated.
