Solar combined heating, cooling and power trigeneration systems are promising technologies that can play a vital role in decreasing emissions, increasing energy efficiency and renewable energies’ share in residential energy consumption. In the studies regarding solar systems, not many studies are dedicated to eva‎luating the possibility of replacing conventional solar collectors with photovoltaic/thermal (PV/T) collectors, which not only are capable of producing high temperature heat, but can also produce electricity simultaneously. Studies show that flat plate and concentrating types of these collectors can be properly used to run single effect and double effect absorption chillers, since these collectors can provide temperatures above 100 oC in a lower surface area. Therefore, this study intends to investigate the potential of these collectors to provide heating, cooling and power, and also to compare the performance of flat plate and concentrating types. The CPV/T system has a total efficiency of 43.2% and can produce 3010 kWh electrical energy with the average electrical efficiency of 10.2% and 4140 kWh thermal energy with the average thermal efficiency of 33% in a year. Also the PV/T system has a total efficiency of about 72.4%. It is capable of producing 21400 kWh electrical energy with the average electrical efficiency of 56.1% and 1260 kWh thermal energy with the average thermal efficiency of 16.3% throughout the year.
