Experimental‐Numerical Investigation of the Photovoltaic Thermal System with Polypropylene Heat Exchanger: Case in Morocco

IET Renewable Power Generation, Volume 19, Issue 1, January/December 2025.
The average thermal efficiency of the PVT system, between 32.99% and 51.15%, is lower than literature values due to imperfect thermal contact between the polypropylene heat exchanger and the PV‐PVTP, along with a limited irrigated surface area of 70%. ABSTRACT This study uses experimental and numerical methods to evaluate a hybrid photovoltaic‐thermal ...
