- A unified, systematic method, based on vector algebra, has been presented from which numerous geometric results, important to the effective collection of solar energy, can be deduced. Results were obtained in a straightforward manner from first principles. Since the results are general in nature, local weather bureau data can be used effectively when comparing various proposed systems. Furthermore, the generality of the results allows the influence of system parameters to be investigated with a minimum of difficulty. Specifically, the geometry of the sun-Earth system and the orientation of surfaces on the Earth relative to the sun have been specified in terms of local terrestrial coordinates. Also, an analysis of ground shadowing and the shadowing of adjacent collectors was developed. The analysis was developed in sufficient generality to allow direct extension to situations not considered explicitly. For instance, the determination of tracking requirements and rates can be determined for various collector geometries by direct application of this method. Also, more complicated collector shadowing problems, such as those which occur near existing structures, can be analyzed.
