Research on concentrating solar power (CSP) technologies began in 1979 in China. With pressure on environmental and energy resources, the CSP technology development has been accelerating since 2003. After 30 years of development, China has made significant progress on solar absorbing materials, solar thermal-electrical conversion materials, solar energy storage materials, solar concentrator equipments, evacuated tube solar trough collectors, solar thermal receivers, solar dish-Stirling systems, solar high-temperature air power generations, and solar power tower system designs. A 1 MW solar tower plant demonstration project landmark is currently being built in Beijing, to be completed by 2010 with a maximum temperature of 390°C and pressure of 2.35 MPa.

Photovoltaic thermal collectors (PVT) combines technologies of photovoltaic panels and solar thermal collectors into a hybrid system by attaching an absorber to the back surface of a PV panel. PVT collectors have gained a lot of attention recently due to the high energy output per unit area compared to a standalone system of PV panels and solar thermal collectors. In this study, performance of a liquid cooled flat PVT collector under the climatic conditions of Abu Dhabi, United Arab Emirates was experimentally investigated. The electrical performances of the PVT collector was compared to that of a standalone PV panel. Moreover, effect of sand accumulation on performance of PVT collectors was examined. Additionally, effect of mass flow rate on thermal and electrical output of PVT collector was studied. Electrical power output is slightly affected by changes in mass flow rate. However, thermal energy increased by 22% with increasing flow rate. Electrical power output of a PV panel was found to be 38% lower compared to electrical output of PVT collectors. Dust accumulation on PVT surface reduced electrical power output up to 7% compared with a reference PVT collector.
