“…Because the problem of the PV solar module power output and efficiency is coming from overheating the PV modules. Many manufacturers and researchers investigated different ideas about the effects of heat/temperature on PV module, PV module turns only 15% to 20% of incoming energy from the solar light into electricity, and however, the remaining part of the energy is transformed into heat [5,16,40]. Therefore, the temperature effects on the PV solar module performance is very big, can decreases the power output by 10% to 25% [40].…”

“…The losses caused by these components influence the PV solar module efficiency and power output. In the PV solar energy generation process, only 15%-20% of incoming sun energy is used by the PV module, whereas the rest of the energy is transformed in the form of heat, which is called thermal losses [5,16,51,52]. When the PV solar module temperature increases, the power loss is also increased [40].…”

“…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. Two of them are used to reduce the operating temperature and then enhance the PV solar module's performance.…”

“…Each component of the system directly correlates with the PV solar energy generating efficiency [12]. The PV solar power output and its efficiency depend on environmental weather conditions like solar radiation, wind speed, snowfall, ambient temperature, and PV module orientation [3,13,[15][16][17].…”

“…The PV module of silicon cell temperature rise by 1 0 C reduces the efficiency by 0.4% -0.5%. In addition to minimizing the power output, it also affects the PV solar modules lifespan [6,16,22]. IRENA2019 [5] reported that the chemical reactions on the PV solar modules are double for every 10 °C if the temperature increased above the room temperature (25 °C), which caused deteriorate of the PV modules.…”

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.
