In this study, a hybrid system of solar-microturbine with and without a combustion chamber, was investigated in a cold climate region (Edmonton, Canada). We developed a thermodynamic model to analyse the effects of environmental conditions on the system performance and power output during the year considering monthly changes in temperature, daylength and solar radiation using real climate and geographical data. The results showed that for a 30 m2 dish collector aperture area, the cycle outlet power was estimated from 3.70 kW in winter to 9.87 kW in summer, while the lowest and the highest cycle efficiencies were 19.44% and 35.07%, respectively for sunny days. The performance of the cycle was also compared with different climates and latitudes in Toronto and Phoenix. The total efficiencies in Edmonton were similar as that in Phoenix in summer but much lower in winter. However, the total electricity output in summer was higher in Edmonton than other two cities. It is found that the highest electricity output in winter is only a half of that in summer day in Edmonton. Furthermore, the cycle could achieve the highest total daily electricity output and fuel consumption in Edmonton in summer due to longer daylength, and higher latitude despite a colder climate if including a combustion chamber. Particularly, more than a half day has no electricity output in Edmonton in winter day if without combustion chamber. Therefore, it demonstrates that this state-of-the-art hybrid system can produce electricity and recover heat in a cold climate region but the climate effects should be considered.
