Abstract:
A hybrid photovoltaic/thermal (PV/T) system is
having the capability to convert solar energy to both electricity
and thermal energy simultaneously and these systems can use to
accomplish the energy demand of buildings. Performance
analysis of such systems becomes essential to design PV/T
systems matching with the operating conditions. It is essential to
extend the energy flow analysis used in this regard considering
economic limitations especially for urban applications. In this
study a practical method to accomplish the energy demand of a
building from a PV/T system is proposed and evaluated through
a thermo-economic model. The performance of the PV/T
collector is analyzed under different operating conditions in Sri
Lanka. The responses of energy storage and local grid according
to demand variations of the building are evaluated considering
the economic aspects. Life cycle cost of the PV/T system is
computed to assess the economic viability of harnessing energy
from solar energy. Furthermore, the capability of deploying PVT
technique and the potential to harvest solar energy in Sri Lanka
is evaluated through conducting case studies for different
locations.
