“…the researchers outlined on optimization of panel cooling using spray water which was addressed as an effective method for the hot region, the result showed that the solar array e ciency was increased by 16.65%, also they conclude that this design need less space and also it is less expensive compared with other cooling system [9]. The PV performance was investigated [10] by examining the effect of water spray angle, as well as the distance between nozzles and PV, quantity of nozzles and oscillating water spray they conclude that the e ciency increase to 19.78% with decreasing spray angle to 15° which leads to decreasing in the panel's from 64° C to 24° C. with decreasing the space between nozzles and PV panel to the smallest distance which was 10 cm the power output was increased to 25.86%. The authors progressed a cooling system which consist of three nozzles with 90° spraying angle, a water pressure 1.5 bar and an on/off controller was managed as 30 s on 180 s off was capable of maximizing the e ciency by 2.09°C and the panel temperature was minimized up to 24°C, so they got an effective cooling with minimum water consumption [11].…”

“…the results showed that the simple design was able to maximize the e ciency by 1.6% and 8% maximization of daily average electrical e ciency. [19] they developed a novel type heat exchanger positioned at the back of the panel to cool down the cells by using air, the maximum improvement they came with in the voltage and output power were 1.3 volt and 7.4 watt respectively. Another study by [20] a cooling chamber attached with three different pane orientation with 60°, 30° and 0° angle to the back side of PV panel with two different ow directions up ow and down ow.…”

In this study a front surface spray water cooling system with a zigzag pattern was experimentally and theoretically designed and investigated. Since the effectiveness of any photovoltaic panels can be adversely affected by various weather-related conditions such as solar radiation intensity, ambient temperature and dust accumulation, and the temperature and rate of flow of water that is used for cooling. ANSYS Fluent was utilized to predict the effects of the proposed system on photovoltaic (PV) power production. The findings indicated that the proposed system, when operating at a rate of 5 L/min water, enhanced efficiency of PV by 20.25%, whilst providing a pristine and dust-free surface. The simulation results indicated that the solar radiation is mostly affecting parameter in increasing the power production with implementation of water-cooling system, upon an increase of 100 watt/m2 in solar radiation, the PV power production augmented by 16.6%. Furthermore, decreasing the water inlet temperature by 5°C with a 5 L/min volume flow rate resulted in an increase in panel power production by 2.25%. Though, the ambient temperature has a slight influence on PV power production at all water volume flow rates.

“…Incidence angle and electrical losses with climatic parameters are studied in [78]. Air temperature is another important parameter in the analysis of hybrid PVT system performance, which is discussed in [79].

A Hybrid Photovoltaic Thermal (PVT) system is one of the most emerging and energy-efficient technologies in the area of solar energy engineering. This review paper provides a comprehensive review of hybrid PVT systems in the context of the history of PVT, general classification, and parameter analysis. Several cell technologies with spectrum analysis are discussed to understand the application’s ability and energy efficiency. Hybrid PVT concept, characteristics, and structure analysis is also discussed in this study. An extensive analysis on the classifications of hybrid PVT systems from the recent literature is also presented here. These literatures are identified based on several criteria. In order to provide a complete and energy-efficient technology, an innovative classification of the hybrid PVT system is proposed in this paper. This proposed classification is a combination and upgrade of various existing classifications mentioned in recent research studies. Parameters have a significant and unavoidable impact on the performance and efficiency of the hybrid PVT system. A brief analysis of different parameters and the optimization of the system is conducted after reviewing recent research articles. This analysis provides insights into the impact of parameter variations on the system. A novel parameter model comprising parametric and optimistic analyses is also presented in this paper. It provides a detailed parametric description that significantly affects the performance and efficiency of the hybrid PVT system. Finally, the assessment focuses on a critical analysis of the main challenges in adopting PVT technology and suggests ways to overcome these barriers.

This study combines simulations and experiments to study the heat interactions between various types of roofs and the photovoltaic (PV) modules installed on them. Specifically, the performance of PV modules on a clay roof was compared with their performance on two types of metal roofs, a Box-profile metal roof and an Orientile metal roof, which differ in shape and geometry. Additionally, this study examined the cooling potential of three common metal roof pigments, iron (iii) oxide (Fe2O3), titanium dioxide (TiO2) and basalt, on roof-installed PV modules. An unpigmented roof was also studied for comparison purposes. Model development and simulation were implemented in COMSOL Multiphysics, and the simulation results were validated and compared with field experiments. The maximum open-circuit voltages of the PV installations were found to be 21.096 V for the clay roof, 20.945 V for the Box-profile metal roof and 20.718 V for the Orientile metal roof. This study revealed that the unpigmented roof had higher solar cell temperatures compared to the pigmented models, with temperature gains ranging from 2.2 °C to 2.71 °C. Moreover, the unpigmented model displayed significantly higher surface radiosity than the pigmented models. The performance output of the modules also varied depending on the metal roof sheet shape and geometry, with the Box-profile metal roof yielding better results than the Orientile metal roof sheet. These results indicate that a specific roof pigmentation may have a small impact on a single PV module, but it can become significant in a large array of modules, especially if cooling through natural convection is hindered.
