Solar energy calculations

Keith E. Holbert, Devarajan Srinivasan

Research output: Chapter in Book/Report/Conference proceedingChapter

Abstract

This chapter presents calculations of the sun's position as a function of location, date, and time. In addition, direct, diffuse, and reflected components of solar insolation on a tilted surface are also determined. This computational approach is applicable to both thermal collection/conversion processes and photovoltaics (PVs). Although sun charts are widely used, there are situations in which charts are inadequate and precise computations are preferred. For example, consider fixed PV modules atop residential or industrial buildings in which the value of the electricity varies with date and time. These calculations can be used to determine angles for positioning one and two axis tracking systems to maximize solar energy utilization.
