Abstract
Photovoltaic (PV) panel suffers in low conversion efficiency of the output performance affected by the elevated operating temperature of the PV panel. It is important to keep the PV panel to operate at low temperature. To address this issue, this paper proposes the cooling system using thermoelectric cooling (TEC) and water block heatsink for enhancing the PV panel output performance. These both types cooling system were designed located on the back side of the PV panel to cool down the operating temperature of the PV panel. To evaluate the function for the existing cooling systems, the experiment was subsequently performed for PV panel without and with different design of the cooling system in outdoor weather conditions. By comparing the experimental results, it is concluded that by the hybrid cooling system which combining TEC module and the water block heatsink could improve the output performance of the PV panel. By the reduction temperature of the PV panel by 16.04 %, the average output power of the PV panel has been boosted up from 8.59 W to 9.03 W. In short, the output power of the PV panel was enhanced by the reduction of the operating temperature of the PV panel.
Highlights
Nowadays, the rapid incorporation of renewable energy technologies within the global energy supply infrastructure growing demand, due to the surging oil prices and increasing environmental awareness
By applying the thermoelectric cooling (TEC) module as a cooling system, the output power of the PV panel increased by 1.5 %, followed by PV panel with water cooling with 2.5 %
This paper studies the effect of cooling system for PV panel output performance
Summary
The rapid incorporation of renewable energy technologies within the global energy supply infrastructure growing demand, due to the surging oil prices and increasing environmental awareness. Under different level of solar radiation, the water cooling was observed to be performed rather than PV panel without cooling system when about 9-22 % increasing in output power. It is because the desired temperature may be achievable if the size and capacity of the TEC are well-designed In this present work, the TEC and water cooling system have been proposed in order to improve the output performance of the PV panel. The TEC and water cooling system have been proposed in order to improve the output performance of the PV panel These both devices act as the cooling system to reduce the PV panel temperature by extracting the excesses heat. The last section shows the conclusion of this proposed study
