ABSTRACT:
Due to an ever growing shortage of conventional energy sources, there is an increasingly intense interest in harnessing solar energy. The instant invention is concerned with method and apparatus for the group alignment of solar concentrator micro-mirrors and the maximization of the percentage of incident light that is reflected to the receiver. Novel method and apparatus are taught for the alignment in large groups or ensembles of micro-mirrors of a micro-optics solar concentrator system for single-axis and two-axis tracking. Broadly this invention deals with novel concepts used for alignment in the focussing of light wherever mirrors are used for focussing such as for solar propulsion assist, illumination and projection of light, optical switching, etc. A particularly important objective is the focussing of sunlight for solar power conversion and production. The instant invention can contribute to the goal of achieving environmentally clean solar energy on a large enough scale to be competitive with conventional energy sources.
