A Technical and Economic Study of a Photovoltaic-phase Change Material (PV-PCM) System in Jordan

This work presents a technical and economic evaluation of the application of phase change material (PCM) in the cooling and thermal regulation of photovoltaic (PV) panels. The technical study is performed based on experimental tests carried out on two identical 3.99 kWp PV systems for one full year at the Hashemite University, Jordan. The backside of the first system was integrated with BioPCM. It is a safe, environmentally friendly, and economically sustainable product that is typically employed in the building industry to save energy in HVAC. This PCM has the potential to answer the many concerns associated with the traditional PCMs. The second PV system is used as a reference for performance comparison purposes. The actual performance results show there is an increase of 3.4% in the annual power production due to the application of BioPCM. The annual conversion efficiency is 12.50% for the PV/BioPCM system, while it is 12.08% for the reference PV system. The economic study investigates the viability of the inclusion of PCM in terms of the payback period, net present value, and internal rate of return. These parameters indicate that the PCM investment is economically unattractive at present. (C) 2020 Jordan Journal of Mechanical and Industrial Engineering. All rights reserved
