Rotation-Elevation of Sun Tracking Mode to Gain High Concentration Solar Energy

Power conversion from solar thermal energy to electrical energy is still very cost-intensive. Serious effort has to be given in the development of the concentrator or heliostat structure expenditure which contributing the most expensive component in a central receiver solar power plant. With current development to find alternatives and lower down the capital, an alternative scheme of sun tracking has been developed and feasibility tested. The proposed rotation-elevation mode of sun tracking has significantly benefits use in high temperature and high concentration solar energy applications. Instead of offering stationary location for large and heavy solar powered Stirling engine application, the process of optical alignment works are reasonably easier and less time consuming. This paper at first will highlight and elaborate its concept and follow with some experimental results.
