Abstract: An automated method causes a terrestrial solar cell array to track the sun. The solar cell system includes motors that adjust a position of the array along different respective axes with respect to the sun, wherein a first motor adjusts the inclination angle of the array relative to the surface of the earth and a second motor rotates the array about an axis substantially perpendicular to that surface. The method includes (a) using a software algorithm to predict a position of the sun at a future time; (b) using a computer model to determine respective positions for the motors corresponding to the solar cell array being substantially aligned with the sun at the future time; and (c) activating and operating the motors at respective particular speeds so that at the future time the solar cell array is substantially aligned with the sun.

Abstract: The present application is directed to methods of forming an integral lens sheet for use with a photovoltaic solar cell subassembly. The integral lens sheet is constructed from a parquet member and one or more individual lenses. One embodiment of a method may include positioning an individual lens over each of the apertures in the parquet member. The size of the lenses may provide for peripheral sections of the lenses to overlap the parquet member. Each of the lenses may be welded to the parquet member by directing a laser beam through the peripheral sections and onto the parquet member. The laser beam may form a laser weld between the parquet member and an underside of the individual lenses.
