<p>In this paper, the thermodynamic performance analysis of low temperature<br />power generation system to produce power and hydrogen is investigated. This<br />integrated system is mainly consisted of two sub-systems, which are photovoltaicthermal<br />(PV-T) collector series, and organic Rankine cycle (ORC). The working fluid of<br />ORC sub-system is chosen as R600 organic fluid. The impact of design parameters,<br />such as air flow rate, temperature and pressure of PV-T collector, turbine inlet<br />temperature and pressure, pinch point temperature, on the system performance is<br />considered by Engineering Equation Solver (EES) software program. Also, the effects<br />of refence conditions (ambient temperature and solar radiation flux) on the integrated<br />system performance is analyzed for more effectively system design aims.<br />Keywords: Solar energy, PV-T collector, energy, exergy</p>
