“…The sketch of the proposed device is shown in figure 8. Taking into account the data presented in table 4, the present solar simulation device could be assimilated as being close to class C solar simulator, which is satisfactory for experimental testing the PV or PV/T panels [26][27][28][29][30].…”

The paper presents the design and execution of a solar radiation simulation device, which ensures the adequate operation of thermal and photovoltaic panels by using light sources which have a spectrum close to the one produced by sun at minimum investment costs. The equipment is used for the experimental tracking of the behaviour of photovoltaic panels and solar thermal panels for both short and longer time intervals. The solar radiation simulation device has been developed to provide the radiation necessary for the evaluation of the efficiency and the heating of the solar panels exposed to sun. A system consisting of six OSRAM Ultravitalux 300W high-pressure lamps has been adopted, offering an optimized solution, both qualitatively and economically. The main steps achieved during its execution were: design, pre-dimensioning, verification, final dimensioning, execution and testing. According to the final tests, it was concluded that the proposed device can provide the quantitative and qualitative parameters required for solar radiation simulation in case of laboratory tests.

“…According to the findings of their research, the incorporation of the nanoparticles into the PCM resulted in a temperature drop of the PV module to 59 C. Hudisteanu et al, [18] conducted a numerical study to investigate the viability of non-perforated and perforated six-fin types as passive heat sinks when positioned horizontally and vertically on the back of the PV module. The numerical CFD study has taken into account the speed of the wind, the average temperature of the surrounding air, the amount of solar radiation, and the convective heat transfer coefficient on both the front and the back of the PV module.…”

The temperature of a photovoltaic (PV) module has a significant impact on the module's ability to produce electricity. PV cells module’s passive cooling is critical for increasing electrical efficiency and power output. In this work, two scenarios of the passive cooling technique were presented for use in the cooling of the monocrystalline silicon PV modules. An aluminium finned wall and a combination of aluminium ﬁnned wall with phase change material were connected to the backside of the PV in order to bring the working temperature down and maintain it under the hot climate conditions in southern Iraq. Paraffin wax was employed as a PCM placed into an aluminium container with internal and exterior longitudinal aluminium fins in order to enhance the PCM's poor thermal conductivity, speed up the rates at which it melts and solidifies, and increase the amount of heat that is dissipated through free convection heat transfer. The PV modules were simultaneously tested and compared with a PV reference module under different solar radiation. According to the findings, the average temperature of the PV-Aluminium Finned wall-PCM module is reduced by 19.9 degrees Celsius when compared with the temperature of the reference PV module. This results in an increase in the average maximum output power of up to 23.1% compared to an identical reference PV module. Furthermore, the average electrical efficiency of the PV-Aluminium Finned wall-PCM is enhanced by 23.2% during the testing time from 9:00 AM to 12:00 PM in July 2022 at maximum solar radiation of 1130.7 W/m2 when compared with the PV reference module under the same conditions. This indicates a significant increase in both electrical and thermal performance. The testing took place in July 2022.

“…These approaches are categorized as either passive (no external energy is needed) or active (additional energy is utilized to circulate the cooling fluid). Passive approaches [5,6] include the use of fins or expanded surfaces to facilitate heat transfer, the use of phase change material to absorb heat produced in the panel, the use of heat pipe cooling, and convection via natural circulation water or air cooling. Active approaches [7,8] involve the circulation of air or water over the panel surfaces, both with and without the assistance of fins.…”

“…Temperature impact affects efficiency and panel life span despite greater energy generation [9,10]. Likewise, researchers [5,11,12] have documented the recovery of useful electrical power with considerable changes in the heat dissipation process of solar panels by using various passive or active panel cooling processes. Although cooling clearly increases renewable energy production [5], it necessitates an additional structure that can extract heat from the panel and distribute it elsewhere.…”

Notably, the design and maintenance [13] of a cooling strategy can be expensive, and the cost of system maintenance may outweigh the benefits of increased power generation.…”

The energy sector is interested in sustainable solar power plants. It is obvious that the working temperature of solar panels, which is significantly higher than the specified working cell temperature in hot climes, has a significant impact on efficiency and longevity. The selection of solar panel cooling systems, on the other hand, is worrisome since the choice process incorporates ergonomic, technical, economic, and environmental issues. The goal of this research is to (1) present a multi-criteria decision-making approach that is both quantitative and qualitative in nature for selecting solar panel cooling systems; (2) outrank nine alternative solar panel cooling systems with eleven performance measures for each alternative to assist decision makers in determining the best viable choice; and (3) visualize the relationship between the different solar panel cooling systems and performance measures under consideration. The proposed approach is to compare and rank solar panel cooling systems, as well as their validation and evaluation through sensitivity analysis. When operating efficiency is prioritized, finned air cooling is shown to be the best solar panel cooling technique, whereas thermosiphon cooling is the best alternative when emission reduction criteria are prioritized. A comparison of the findings shows that phase change material cooling and forced convection cooling performed worst in almost all cases.
