In order to solve the freezing problem associated with the traditional photovoltaic/thermal (PV/T) system, a novel heat pipe-type PV/T (HP-PV/T) system was designed and constructed in the present study. Outdoor tests were carried out from May to July, 2010. The performance of the system was also studied. The results showed that the average photothermal efficiency was 41.30% and the photoelectric efficiency was 9.42%. The average first law efficiency of the system was 48.52%, and the second law efficiency of 6.87%

Abstract The present study deals with the techno-economic and environmental analysis of a parabolic trough concentrating photovoltaic/thermal system. Energy, economic and environmental issues of the purposed system have been evaluated and analyzed. The MATLAB software has been used for modeling. The outputs of this software include the amount of energy and electrical productions as well as environmental parameters for different studied areas. Finally, economic analysis and energy savings have been performed to persuade the use of this type of technology to supply the various loads of a building. One of the most important results of this study is the production of 222 060 kW of thermal and electrical energy in Bushehr, which is the largest amount of production among cities and saves energy and revenue from the sale of this amount of energy—231 983 kW and 38 533.24$, respectively. A comparative environmental analysis represents that the largest prevention of CO2 emissions is found in Bushehr with 515 tons per year and the lowest prevention of CO2 is related to Rasht with 34 tons.
