Experimental study on a binary mixture ratio of fatty acid-based PCM integrated to PV panel for thermal regulation on a hot and cold month

This paper presents the thermal regulation for photovoltaic panel by integrating PCM unit of 30 mm and 50 mm thickness. Eutectic mixture of Lauric and Palmitic Acids in the ratio of 69:31 and 85:15 was used to achieve the melting temperature of 35 degrees C and 40 degrees C, derived from average ambient and cell temperature for hot and cold months. This experimental study shows that average increase inperformance ratio from reference panel to 30 mm and 50 mm PCM panels were 1.54% and 2.36%, for March and 1.28% and 1.66%, for December. Further, the average efficiency of the panel was increased from 9.28% to 9.43% and 9.51% in March and 10.19% to 10.31% and 10.35% in December.

Automated summary

The study demonstrated the thermal regulation of photovoltaic panels by integrating PCM units of different thickness, showing a significant increase in performance ratio and efficiency with the addition of 30 mm and 50 mm PCM panels compared to reference panels.
