The main objective of this paper is the modeling of a water-based concentration photovoltaic-thermal collector. This study also aims to investigate on the influence of the cooling water mass flow rate on the temperature and performances of a PV cell in such hybrid system. On the basis of the thermal model, the thermal equation was determined at the steady-state. The numerical resolution of this equation allowed to plot the PV cell temperature profile according to light concentration and for different mass flow rates. It appears that the temperature rises with light concentration and falls down with increase in water mass flow rate towards the inlet temperature of this one. On the basis of the electrical model, diffusion parameters and electrical performance were extracted and plotted according to light concentration and mass flow rate. The results show the decrease of the diffusion parameters with increase of light concentration and their improvement with increase of the mass flow rate. The current density and the short-circuit current density remain practically invariables under mass flow rate effect. But it appears a strong augmentation in voltage, open-circuit voltage, electrical power, electrical efficiency and fill factor when the mass flow rate increases. However, above 0.001 kg.s−1, it appears a drop in the cooling effect of water. This phenomenon is characterized by the slowing down of the favorable effect of an increasing water flow rate.

“…Kazem et al summarized the effects of solar irradiance and ambient temperature on the electrical performance of water-based PVT systems [9]. The power of the PV panels is determined by the amount of solar irradiance, while the cooling water flow and temperature affect the power output characteristics of the PV panels [10]. Gaur et al proposed a PV system model to investigate the performance of a commercial PV module and showed that the electrical efficiency of the system with and without water cooling is 7.36% and 6.85%, respectively [11].…”

A large amount of redundant energy gained from incident solar energy is dissipated into the environment in the form of low-grade heat, which significantly reduces and limits the performance of photovoltaic cells, so removing or storing redundant heat and converting it back into available thermal energy is a promising way to improve the utilization of solar energy. A new combined water-based solar photovoltaic-thermophotovoltaic system embedded in the phase change material (PCM) mainly is proposed and designed. The effects of the water flow rate, cell operating temperature, the presence of PCM, and the thickness of the PCM factor on the overall module performance are explored comprehensively. The maximum thermal power output and the corresponding efficiency of the combined-system-embedded PCM are calculated numerically, The results obtained are compared with those of the PV (photovoltaic) and PVT(photovoltaic-thermal) cells with the same solar operating conditions. In addition, the PVT-PCM system possesses a higher power output and overall efficiency in comparison with the PVT and PV system, and the maximum cell temperature reduction of 12.54 °C and 42.28 °C is observed compared with PVT and PV systems. Moreover, an increased average power of 1.13 W and 4.59 in PVT-PCM systems is obtained compared with the PVT system and the PV system. Numerical calculation results illustrate that the maximum power output density and efficiency of the PVT-PCM are 3.06% and 16.15% greater than those of a single PVT system and PV system in the working time range, respectively. The obtained findings show the effectiveness of using PCM to improve power output and overall efficiency.

In this research paper, a well‐performing solar pump at the minimum cost of project life is designed and installed. Initially, the capacity of submersible pumps and discharge have been determined based on the water requirement of the crop and the size of the field. The total number of solar panels, inverter size, and motor pump system have been designed based on the law of conservation of energy. The two optimization techniques genetic algorithm (GA) and response surface methodology (RSM) have been used for analyzing the pump performance parameters and total cost. The GA tool has been used to determine the optimum tilt angle on which responses namely solar flux, solar panel efficiency, exergy, and pump efficiency should be maximum. Moreover, the performance of the solar pump at the optimum tilt angle has been compared with the 28° fixed tilt angle (latitute of location). For the experimental study solar pump experimental setup of 5 hp power has been installed in Faculty of Engineering and Technology, MJP Rohilkhand University at 28.36°N, 79.43°E. The total cost of the solar pump has been optimized with the help of RSM based on the discharge and head of the solar pump. The new optimization approach reduced the levelized cost of electricity (LCOE) from 0.041 to 0.035 $/kWh and the payback period is reduced from 4 to 3 years. The annual increment in average solar flux and overall efficiency has been recorded to be from 606 to 697 W/m2 and 11% to 14% respectively.
