Energy production using photovoltaic panels seems to be the next promising technology. The only main problem is that the panel's efficiency has a negative relationship with its surface temperature. Moreover, the efficiency drops by 0.5% for each one-degree rising in temperature. In recent years, many attempts have been done to cool the PV panel surface temperature. Different technologies have also been proposed to achieve that purpose .mainly, most of the suggested cooling systems based on the water or air as a working fluid, and the conversion ratio could be enhanced by 22% and 13% when using water and air cooling. Others use Nano-particles to enhance that process, as well as the PCM was also investigated. All these technologies can increase panel efficiency by 3-5%. In this paper, different types of cooling technology are analyzed and categorized.

“…This conversion rate is much higher than the ratio of wind and biomass technology. However, it decreases considerably as the surface temperature increases in the range of 0.45 to 0.5% / ° C for each degree Celsius [1][2][3], depending on the material used in PV fabrication. It has been found that the high operating temperature shortens the life of the photovoltaic module.…”

Photovoltaic modules (PVM) output power is sensitive to fluctuations in temperature and the concentration of solar insolation during sustained disclosure. The 20% of solar insolation will be converted into useful electrical energy, while the rest will be dissipated in the form of heat, which in rotate will increase the operating heat of the PVM and it negatively affects the open circuit voltage (Voc), resulting in a decrease in the power alteration productivity and an irreversible rate of cell deprivation. Appropriate cooling techniques are therefore crucial to preserve the operating temperature of the module under standard test conditions (STC). There are two different methods for cooling PVMs, namely active and passive these methods are subdivided into different techniques which are discussed one by one in literature review; in this paper the techniques for cooling PVMs are comprehensively reviewed

“…Cooling solar panels have been proposed since the late70's as an initial idea and have been developing since. Different cooling methods of solar panels have been proposed and reviewed in [12]. It reveals that they can technically reduce the temperature and increase efficiency; however, easiness, suitability and economic feasibilities are major factors to consider when selecting any system.…”
