Solar Stirling Generator Efficiency

A solar powered Stirling engine is a heat engine powered by a temperature gradient generated by the sun. Even though can run with a small temperature gradient, it is more efficient to use . The mechanical output can be used directly (e.g. pumps) or be used to create electricity. Solar Stirling systems have demonstrated the highest efficiency when considering solar-based power generation system by converting nearly 30% of the sun’s radiation into electrical energy [5]. [pdf]
