An analytical, experimental investigation of the thermal performance of a tubeless V-trough concentrator has been carried out. Considering the energy balance on the receiver plate, a mathematical expression is developed from which the receiver plate mean temperature can be evaluated for each time interval. The good agreement between the experimental results and the analytical predictions indicate that the construction of a tubeless absorber panel might be valuable and the analytical approach might have the potential for further extensions. It has been found, according to the expermental investigation, that the fluid outlet temperatures vary between 69°C and 91 °C from 10:30 a.m. on up to the termination of operation in the late afternoon. This qualifies the V-trough to be a reliable source for providing temperatures in this range that can be utilized in heating and cooling applications.
