Energy, exergy, and economic analysis of a solar photovoltaic …
However, the exergy efficiency of the solar collector is lower than that of the PV cell. The lower exergy efficiency of the solar collector results in a lower exergy efficiency of the PTS. The exergy efficiency of the solar collector is about 11.4% during the heating period and only 8.6% during the non-heating period. (2)
