Open-loop altitude-azimuth concentrated solar tracking system for solar-thermal applications

An open-looped altitude-azimuth concentrated solar-tracking system without additional power was developed in this study. This system adopted the Fresnel lens module to concentrate sunlight on a Stirling engine’s heating head while conducting measurements for the temperature profile of the heating head. We also installed solar panels on both sides of the solar tracking system to supply power to the driving motors and reduce the torque needed for...
