Thermodynamic modeling of solarized microturbine for combined heat and power applications

•Introduced a thermodynamic model for a 100 kWe/165 kWt solarized microturbine.•Electric output of thermodynamic model is within 1.6% of the as-built system.•Fuel use reduced by 26.0% verse traditional microturbine at maximum power output.•Annual operating time is 59.8% fuel only, 12.4% hybrid, and 27.8% solar only modes.•Electrical efficiency most sensitive to ambient air temperature.
