Comparative performance study and techno-economic analysis of different solar water heater in Bangladesh

Abstract

FPC and ETC solar water heater has many potential markets in the camping, outdoors living, and humanitarian sectors in Bangladesh and huge opportunity at winter. The study was conduct to compare the performance of FPC at various flow rates with ETC and techno-economic analysis in Bangladesh prospects.The output water temperature and thetemperature difference of input-output water highest found 64.940C and 28.020C inETC at 4.5 l/m.The efficiency at different flow rate found ETC is 79.28% at 4.5 l/m and FPC is 28.32% at 3.4 l/m. At the stagnant condition the output temperature found highest 890C and 940C of FPC and ETC respectively when the glass surface and covered metal surface of the FPC found 500C and 480C respectively.The highest efficiency found of FPC found 89% at average 145W/m2 daily radiation and of ETC highest efficiency 93% at average 246W/m2 at 2.5 l/m flow rate. The swimming pool in University of Dhaka need Tk.51,98,000.00 and 1155m2 area for FPC, on the other hand Tk. 90,86,000.00 and 770m2 area for ETC to run at winter.
