Measurement the outdoor efficiency of photovoltaic (PV) panels is essential, but it is not likely an exceptional circumstance at any given moment is always repeating itself. A solar simulator was designed and fabricated for the purpose of analyzing the performance of PV panel with and without an air cooling mechanism in indoor test.

Performance Evaluation of Photovoltaic System Using Different Cooling Methods
Journal of science and technology research , 2022
A typical photovoltaic (PV) panel cell has ideal conversion efficiency in the range of 14-25%. The remaining energy is converted into heat and this heat increases the operating conditions (temperature) of PV system which therefore affects the electrical output power of PV modules in the system. Since the output of the PV modules decreases as a result of temperature rise, this effect results in decreased efficiency. Furthermore, if heat is not removed, structural damage to the PV modules will occur, shortening their useful life. To this end, this study presents the distinctive performance evaluation of photovoltaic cells under three cooling conditions to investigate the effect of cooling on the efficiency and output power of the photovoltaic cells. To achieve the set goal, three distinctive cooling techniques were employed for analysis namely forced air cooling, water cooling and natural air-cooling methods. In conclusion, results from analysis show a significant improvement in efficiency and output power of the PV module with the cooling system, thus indicating an improvement in the potential of PV system output as a renewable energy source.

The paper deals with the three-dimensional theoretical and numerical investigation of the electrical performance of a Photovoltaic System (PV) with active fluid cooling (PVFC) in order to increase its efficiency in converting solar radiation into electricity. The paper represents a refinement of a previous study by the authors in which a one-dimensional theoretical model was presented to evaluate the best compromise, in terms of fluid flow rate, of net power gain in a cooled PV system. The PV system includes 20 modules cooled by a fluid circulating on the bottom, the piping network, and the circulating pump. The fully coupled thermal and electrical model was developed in a three-dimensional geometry and the results were discussed with respect to the one-dimensional approximation and to experimental tests. Numerical simulations show that a competitive mechanism between the power gain due to the cell temperature reduction and the power consumption of the pump exists, and that a best c...
The objective is to analysis the cooling system in PV module development considering the know-how in developed and developing in the world, in order to determine the best system for UFVa prototype. In terms of methodology is to pondering the constructive aspects of operation, maintenance, and if possible to restrictions on the type of area for installation and principal the designed for that local specific longitude and latitude weather conditions. Also determine three main types of cooling systems. As results, we have the PVT collector-liquid and/or air ventilated PV with heat recovery. In this project the type of coolant used is the PVT-liquid. This water is redirected to the coolers installed in the photovoltaic modules of the plant to main line, and subsequently returns to the process without impacting the operation of the dam. The choice of this type of technology was based on an analysis of the region in which the plant will be installed, noting that the climate, availability of coolant, ambient temperature and solar radiation index, indicated for the use of the PVT-liquid system. With these results we conclude that the three types for constructing the pre-prototype is coolers of the coil (two variations) and multiple-channel.
