“…A hybrid PV integrated with phase change material (PCM) as well as graphene nanofluid (NF) having different volume concentrations was studied by Wahab et al [125]. It was deduced that the maximum thermal coupled with electrical exergy performance for PV/PCM/NF were 1.78% at 20 l/min and 13.02% at 40 l/min with 0.1 vol.% of nanofluid as represented in Fig.…”

Fixed tilted, single‐axis tracking, and dual‐axis tracking PV systems are compared for one‐way energy meters and net‐energy meters. Optimization of the tilt angle and azimuth angle based on the load profile in one‐way energy meters enhances the net present value. The higher energy demands of summer can be met by lower tilt angles while the PV energy peak can be shifted towards the higher load hours by adjusting the azimuth angle. The results show that the net‐energy system with single‐axis tracking outperforms dual‐axis tracking and fixed tilted systems for a residential PV system one‐way meter, the load curve can be used to optimize the tilt angle and azimuth angle of a fixed tilted system to achieve a higher net present value (NPV) with added advantages of lower building cooling loads and lower self‐shading losses of the PV system. The comparison between the base‐case PV system and the optimized system of a fixed tilted system on a one‐way energy meter in Islamabad and Lahore shows a 15% and 13.7% higher NPV, 3.5%, and 3.6% lower simple payback period respectively. The optimized PV energy system also achieved 28% and 25% more savings in the cooling load of the houses in Islamabad and Lahore, respectively.

“…The temperature level of the PV solar module surface must be uniform and suitable unless the solar energy generation systems cannot give the desired results. Consequently, the cooling techniques are one of the best solutions to remove or reduce heat from the PV module's surface [58][59][60]. In literature [16,22,41,61], there are two major cooling techniques.…”

PV solar energy is the upcoming king of the energy source in the world, which is the fastest growing, most available, sustainable, clean, and environmentally friendly renewable energy. The essential characteristic of PV solar energy is generating the maximum power at mid-day. At the same time, the energy demand is high during the daytime. Due to this, PV solar energy replaces the conventional energy demand at peak periods. The sun is the source of PV solar energy, and it changed into electricity directly by using solar cells, which are made from semiconductor materials called silicon. Therefore, PV solar energy plays a crucial role in providing usable energy, and as well as reducing carbon dioxide emissions. However, the solar energy generation systems not achieved the desired efficiency yet, because of many unsolved problems like weather conditions, losses, materials made by and so on. The aims of this paper is to review the current literature on the improvement of the PV solar energy generation system's overall performance. First, to figure out the existing challenges, like environmental factors and natural phenomena that affect the PV solar modules efficiency. Then it presents the techniques that are used to enhance the PV solar modules overall performance. Finally, to propose the best ways and techniques to improve the PV modules efficiency and suggest to further studies.
