ABSTRACT:
The invention relates to a rail-type solar tracking system with a focusing function. The invention includes a plurality of support elements, a Fresnel lens, a rail platform, a load bearing platform and a pushing device. The system moves a solar cell on the load bearing platform to a focus position where sunlight is focused by the Fresnel lens to collect solar energy. Hence, the invention collects solar energy without moving heavy lens so as to reduce power consumption and improve the electric power generating efficiency of the solar cell.
