Solar power systems

Abstract

A review of the principal solar power systems is presented. The nature of the solar energy source is discussed starting from the energy output of the sun and covering briefly the important atmospheric effects to characterize the available solar energy on the earth's surface. The various methods for capturing solar energy are presented: flat-plate, concentrating, photovoltaic, and other collectors. Energy storage methods are presented briefly for thermal, chemical, electrical, and mechanical storage approaches. An application of solar power systems in interaction with a conventional electrical utility system is presented in terms of mode of operation (base, intermediate, and peaking), reliability, capacity displacement, and energy displacement. An economic evaluation of selected solar power systems compared to conventional electrical generation plants is presented. Conclusions are drawn as to the conditions under which solar power systems may become economically competitive. A preliminary indication of market capture potential is discussed.
