The experimental study is aimed at analyzing photovoltaic module’s thermal and electrical performance (PV) with back surface
cooling under Malaysian tropical climate conditions. The performance of a passively cooled PV module integrated with
biomaterial (moist coconut fiber) was compared with a photovoltaic thermal (PVT) system with water circulation at the rate of
0.02 kg s
-1
and a reference PV module. The study observed that the passively cooled PV module succeeded in reducing the
module surface temperature by more than 20%. However, the PVT system reduced the temperature only by less than 17%. The
electrical energy efficiency was improved remarkably in the passively cooled PV module by almost 11%, but the PVT system
managed to increase the electrical efficiency by 9%, approximately. It can be concluded that nature-inspired coconut fiber-
based cooling can be one of the potential alternatives to active cooling methods.
1. Introduction
For decades, fossil fuels have been used to meet humans’
energy demands, primarily through electricity production.
The role of crude oil and natural gases has become more
questionable for decades as they come with the price. Energy
production through fossil fuels has caused as much detri-
mental impact on the environment as harvesting them. As
mentioned by Alobaid et al. [1], heavy carbon emissions
and accelerated global warming have resulted from extensive
fossil fuel usage. Not only are they a nonrenewable energy
source, but also fossil fuels are unreliable and potentially
put our environment at stake. Solar energy is one of the
many forms of renewable energy mentioned by Owusu and
Asumadu-Sarkodie [2] which is being used as an alternative
to produce carbon-free energy and mitigate negative climate
change. As noted by Kirpichnikova et al. [3], solar energy is
a very sustainable and reliable source of energy as it is eter-
nally available at the same time, eco-friendly. Incorporating
solar energy by installing solar panels either in the house-
hold or to meet industrial needs has proven effective and
encouraging.
About 5 to 20% of sunlight is in contact with the PV
module, generating electrical energy. In contrast, the
remainder of the sunlight is either radiated back to the
atmosphere or absorbed into the panel through conduction
as heat [4]. Consequently, the heat will cause a dramatic
increase in the surface temperature of the PV module. As
