“…This study deduced that the modified module with reflectors produced 5 % more PV power than the two-axis solar tracking systems without reflectors and 12.5 % more PV power than the fixed PV module with a 26 ° inclination angle. M. Asvad et al [27] investigated the effects of several types of reflectors on PV panel performance. They discovered that those reflectors may increase the power output of the solar module by up to fourfold, but that an increase in module temperature would have a negative impact on the module's efficiency.…”

Even though the southeast region of Algeria, especially Ouargla city, enjoys a lot of sunshine all over the year, fixed photovoltaic (PV) solar panels are not sufficient due to two main reasons. Firstly, these panels are unable to capture sunlight during the early morning and late afternoon, and secondly, their efficiency is low, requiring the use of economical methods to enhance their performance. To overcome these limitations, this research suggests incorporating commercial reflectors to enhance sunlight capture. Furthermore, this paper compares the effects of three types of reflective materials: mirrors, aluminium, and transparent glass, on the performance of the PV module. To achieve this objective, reflectors are installed at the top and bottom of the PV module at their optimal tilt angles. Moreover, the effect of the adjacent module's mirrors was studied by installing two big mirrors (3X). The obtained results show an average improvement of 14.24 %, 11.41 %, and 4.7 % in the electrical energy generated by the PV panel with mirrors, aluminium, and transparent glass, respectively, compared to the module without reflectors. Subsequently, in the large mirror case, the results were positive, with an average 20.84 % increase in the maximal electrical power produced compared to the conventional one.

“…They observed the simulation results and found that the improved average annual solar irradiation in static condition is 64% and in the two-axis solar tracked system is 111.28% respectively. Avsad et al [42] investigated the performance of a solar module paired with several reflector configurations, including hybrid, parabolic, flat, and quadrangular, at reflector inclination angles ranging from  50 to  80 . They discovered that reflectors might increase the power output of the solar module by up to four-fold.…”

An experimental investigation was carried out on novel solar water heater that utilizes a flat reflector positioned underneath the absorber tubes. Experiments were conducted at National Institute of Technology Patna, India, having latitude 25.61°N and longitude 85.14°E and constant insolation of 1000 W⁄m^2 . The experimental data were collected for different reflector positions i.e. δ = 0 mm, 15 mm, 30 mm, 45 mm, and 60 mm and six mass flow rates of working fluid i.e. 0.0056 kg/s, 0.0097 kg/s, 0.0138 kg/s, 0.0207 kg/s, 0.0277 kg/s, and 0.0346 kg/s. The obtained experimental results exhibited that the location of the reflector relative to the absorber tubes significantly affects the thermal performance of the system. The effect of the mass flow rate on the outlet temperature, thermal performance, and overall performance has also been studied. For the present system under energy and exergy analysis, the optimal position of the reflector was found of δ = 30 mm. The results showed that the solar water heater with an optimally positioned reflector has a 23% increase in thermal efficiency compared to the solar water heater without a reflector. The novelty of using a flat reflector underneath absorber tube is to provide heat to rear side of the absorber tubes after reflecting the insolation falling on the reflector and hence improvement in the thermal performance of the solar water heater. The scope of present system includes providing an eco-friendly and energy-efficient solution for residential and commercial hot water needs. Limitations of the present study are requirement of sufficient roof space and direct sunlight. The use of reflectors has implications for energy savings, more efficient system designs, and enhanced thermal performance.
