Pakistan is among the developing countries of the world which suffers from worst energy crises. The energy crises of the country could be overcome by utilization of renewable energy sources such as solar energy. This research presents an experimental study on the performance investigation of solar dish sterling engine. The designing of the dish and sterling engine was performed on AutoCAD software. The system was fabricated locally, and experimental study was performed for the weather conditions of Sukkur, Sindh, Pakistan. The system consisted of a parabolic dish, solar reflectors, gamma Sterling Engine (double acting type), fan blades, flywheel and dynamo (alternator) having capacity to generate almost 100 watts of electricity. The horizontal radiations falling on dish were directly focused on the receiver (displacer) end of the sterling engine. The heat produced due to solar radiations was used to run the gamma type sterling engine. The experimental study that the total efficiency of the sterling engine was about 70.96% by neglecting the losses.
