4.3 Studying Long-Term Dynamic Performance of the PV/T
Systems under Real Climatic Conditions
Steady-state performance of various PV/T systems has been theoretically and
experimentally studied as a result of the previous researches, and no obvious space
could be seen to further develop the research work in this regard. However,
dynamic performance of the PV/T systems under real climatic conditions has not
yet been fully examined, particularly at long-term (seasonal or annual) scheme.
This work remains certain challenges as several uncertain factors, e.g. influence of
irregular variation in the solar radiation, ambient temperature and wind speed onto
the
system
performance,
are
difficult
to
predict.
Combined
theoretical
and
experimental study may enable a solution to the problem.
4.4 Demonstration of the System Operation in Real Building
and Feasibility Study
It is known that PV/T technology has been used in many practical projects.
However, there is little report found that focused on assessment of the system's
performance under real climatic conditions. Research could be developed from
this angle to develop, install and monitor the PV/T systems in real buildings. This
will allow assessment of the real performance of the system including reliability
and commercialisation potential. Further, feasibility of the system used in real
buildings could be examined. This work could possibly channel up the research
outcomes to commercial application.
4.5 Economic and Environmental Analysis
Current works on economic and environmental analysis of the PV/T system have
been conducted on laboratory and computer modelling bases. Further work could
be extended in this regard to take into account effect of the climatic conditions to
the system's performance through long-term measurement.
5 Conclusions
The overview and critical analysis into R&D achievements and practical appli-
cation of the PV/T technology have been carried out. This would help understand
the current status of the PV/T technical development, identify the existing barriers
remaining in this field, establish the associated strategic plans, standards and
