“…A phase change material (PCM) was used in direct contact with the backside of the PV module (Atkin and Farid, 2015). Evaporative cooling and fins attached to the backside of two PV panels was investigated by Chandrasekar and Senthilkumar (Chandrasekar and Senthilkumar, 2015). It was found that the PV temperature reduced by 12%, and electrical efficiency improved by 14%.…”

The performance of photovoltaic (PV) panel having staggered metal foam fins was examined experimentally in Baghdad, Iraq. Three staggered metal foam fin configurations attached to the backside of the PV panel were studied. The measured parameters were front and back surfaces temperature, open voltage and current circuits, maximum power, and PV efficiency. It was noted that the maximum electrical efficiency enhancement was 4.7% for staggered metal foam fins (case III) than the reference PV panel. The operating temperature of the cell was increased when the value of solar intensity was high. Thereby, the electrical efficiency was decreased. It was found that the metal foam fins decreased the PV temperature by 2-3 oC.

In this study, an experimental prototype was built to examine the use of an underground water tank as a heat exchange medium with the soil to reduce photovoltaic (PV) panel operation temperatures and simultaneously improve PV efficiency. Three PV systems were evaluated: a benchmark PV panel without cooling (panel A); a PV panel with water spray cooling (panel B); and a PV panel with evaporative cooling (panel C). The cooling techniques in modules (B) and (C) were used to investigate the effects of underground water on the performance of PV panels in arid conditions. Four cases were devised as follows: spray panel back cooling (I), spray front and back cooling (II), spray front and back cooling using an Arduino controller (III), and repeating case III with different water flow rates (IV). Readings were taken from 9:00 am to 4:00 pm from May to August. The experimental results showed that the use of underground water spray cooling led to reductions in the temperature of PV panel B, 14°C, 17.6°C, 18.8°C, and 22.7°C for cases I, II, III, and IV, respectively, when compared with the uncooled panel, and efficiency improved by 3.5%, 4.8%, 18%, and 23.1%, respectively.

“…For the cooling of the PV modules, different techniques have been studied . Among these techniques are the passive cooling by air or water, an active cooling by air or water, integrating the PV module with the phase change materials (PCMs), thermoelectric cooler (TEC), and distillation unit . The last technique is considered an attractive solution for water and energy problems in rural areas.…”

Summary In this paper, a novel hybrid photovoltaics/thermoelectric cooler (PV/TEC) distillation system has been introduced. The limitation for distillation system working under hot arid climate is the heat removal required for the condensation process. The novelty of the proposed system is that it utilizes TEC to improve the condensation process. The proposed system composed of two porous layers separated by an air gap. The upper porous layer is installed at the back of a PV module; the lower porous layer is installed at the top of a TEC modules layer. This system can provide the demand of electricity and potable water for those people who live in rural areas (using one unit or more). The proposed system prevents PV module from overheating and actively enhancing the condensation process of the evaporated water. A steady‐state mathematical model has been proposed. This model was solved and simulated by equation solver software. Wind speed, solar radiation, and ambient temperature effect on the system performance were simulated and discussed. Results showed that the maximum productivity of the system reached an ambient temperature of 298 K, solar radiation of 1000 W/m2 and wind speed of 5.5 m/s. The maximum yield of the system was 4.2 kg of distilled water per day with a net electrical output power of 73 W with an overall efficiency of 57.9% and PV cell efficiency of 12.32%.
