Water Cooling System

Sun-oriented energy is a resource of energy on earth. Sun-based energy can be gotten as warmth to create power or it is additionally conceivable to change over sun-based energy straightforwardly into power. The main objective of this project is to catch maximum solar radiation from the sun and increase the overall efficiency of solar panels. To design a cleaning mechanism that runs across the length of the panel. To avoid dust-associated problems on the solar panels. The temperature in case of water cooling system was lowered down to 410C from the ambient temperature 440C at 14:00 in the morning of 21/09/2020. The power output was 4.789W and in case of set up having dust on the surface of the solar panel the temperature rose to 490C with power reduced to 4.00185W. The temperature in case of water cooling system was lowered down to 400C from the ambient temperature 430C at 14:00 in the morning of 22/09/2020. The power output was 4.89W and in case of set up having dust on the surface of the solar panel the temperature rose to 490C with power reduced to 4.00185W. The outcomes for day 3 of the experimentation were also recorded on 23/09/2020 and the setup with a cooling system produces a maximum power of 5.20 W by lowering the temperature to 370C from the maximum ambient temperature of the day 410C

Pv Systems

High temperature is the primary challenge in the development of solar photovoltaic (PV) systems in an arid climate. A rise in temperature diminishes the performance of the PV systems and shortens their lifespan. The goal of this manuscript is to develop an analytical model to predict the temperature of PV panels under a passive cooling system for an arid environment. Taking into consideration the link between solar panel temperature and its conversion efficiency, Kirchhoff’s and Ohm’s laws for a complex circuit were applied to calculate the heat flux in the solar panel system, and hence obtain the temperatures of each layer in the system. Closed-form analytical expressions for temperature, output power, and conversion efficiency of the solar panel were deduced and presented as functions of solar irradiance, ambient temperature, emissivity, wind velocity, tilt angle, and dimensions of fins. Comparison between the results presented in the literature and those predicted by the developed analytical model validated the presented model. Moreover, the length of the fins required for safe thermal operation of solar panels in harsh desert environment were also obtained from analysis. Furthermore, the effect of using such a cooling system on the temperature and efficiency of the solar panels was verified by using the developed model under real conditions in Dammam city during summer and winter seasons. The results showed that the optimized heat sink could raise the solar panel power by 8.7% during summer and by 6.5% during winter.

Optimal Set

In order to ensure the reliable and safe operation of the electric driving motor of the articulated dump truck, water cooling system is installed for each motor. For the best performance of the water cooling system, not only the heat transfer should be enhanced to maintain the motor in relatively low temperature, but also the pressure drop in the water cooling system should be reduced to save energy by reducing the power consumption of the pump. In this paper, the numerical simulation of the cooling progress is completed and the temperature and pressure field distribution are obtained. The multi-objective optimization model is established which involves the cooling system structure, temperature field distribution and pressure field distribution. To improve the computational efficiency, the surrogate model of the simulation about the cooling process is established based on the Response Surface Methodology (RSM). After the multi-objective optimization, the Pareto optimal set is obtained. The proper design point, which could make the average temperature and pressure drop of the cooling system relative desirable, is chosen from the Pareto optimal set.

Overall Efficiency

An innovative low power (5W) consumer grade dual face PV solar panel assembly is presented in this research. The authors propose capitalizing indirectly on the shadowed face of a typical solar panel by augmenting the panel’s total active area of exposure (via the panel’s “back side” and respective “deflectors”) and aiming at an increase in the overall efficiency of the assembly. Standard environmental operating conditions were taken into account. No CPV were used. The resulting power output profile of this unit is presented in detail and compared with the output of a single sided “standard” solar PV module configuration. In addition, under similar design and operating environmental variables, the behavior of crystalline cells panels is intended to be contrasted with thin film panels’ as variants of this proposed solution.
