3. Consider a parabolic trough concentrator with an aperture width and length of 1.4 m and 26 m, respectively. During a given day, the average direct solar irradiance on the concentrator is 650 W/m. The efficiencies of the concentrator, receiver, and electrical generator are 0.91, 0.83, and 0.95, respectively. If the temperature of the working fluid in the receiver is 600C, find the maximum possible electrical output power. The temperature of the surroundings is 10C. 3.
