Abstract

A solar energy conversion system comprises a plurality of mirrors (8) arranged on the ground in arrays (7) for collecting and directing solar radiation towards a heat exchanger (6) of a Stirling engine (3) for heating a working fluid, namely, helium for the Stirling engine 3. The Stirling engine (3) is mounted on a platform (19) on the top of a mast (5) and is coupled to an electricity generator (20) for producing electricity. The Stirling engine is operated in accordance with an alpha Stirling cycle. The mirrors (8) are pivotally mounted about respective perpendicular axes for following the trajectory of the sun as it traverses from east to west across the sky. The Stirling engine (3) together with the heat exchanger (6) is also pivotally mounted about respective perpendicular axes for facilitating alignment of the heat exchanger (6) with the mirrors (8) as the mirrors (8) are pivoted to follow the trajectory of the sun across the sky as it traverses from east to west.
