P
hotovoltaic applications are the means that converts solar
light into electricity. However, the photovoltaic panels’
efficiency is highly affected by heat storage and surrounding
heat leading to decrease in their efficiency. To solve this problem
researchers led to propose a new hybrid photovoltaic thermal
system PV/T that generate electricity parallel to absorbing heat
for other applications. Entering into the era of nanotechnologies
it encouraged more researchers to utilise these technologies in
PV/T system using suspension of nano particles in the base fluid
called nanofluids. This paper presents a numerical simulation
for thermal regulation of PV/T systems using ANSYS Fluent
software for multi wall carbon nanotube (MWCNT—water based)
nanofluids. The results were validated with experimental results
using nano particles volume concentrations ranging from (0-
0.3%) at nanofluid flow rate of 1.2l/min. Photovoltaic panel
temperature decreased by 11ºC at peak solar radiation using
0.075% MWCNT concentration. The system efficiency based on
the numerical simulation achieved an overall value of 60.1% over
the test period. A very good agreement between the numerical
and experimental results was also achieved.
