The Effects of Regional Insolation Differences upon Advanced Solar Thermal Electric Power Plant Performance and Energy Costs

Abstract

This paper presents the performance and cost of four 10-MWe advanced solar thermal electric power plants situated in various regions of the continental U.S. Each region has different insolation characteristics which result in varying collector field areas, plant performance, capital costs, and energy costs. The paraboloidal dish, central receiver, cylindrical parabolic trough, and compound parabolic concentrator (CPC) comprise the advanced concepts studied. This paper contains a discussion of the regional insolation data base, a description of the solar systems’ performances and costs, and a presentation of a range for the forecast cost of conventional electricity by region and nationally over the next several decades.

Activity and accomplishments in dish/Stirling electric power system development

“…1-1 (4) Larger temperature differences than expected were seen on the heater cage in the solar-only receiver tests. These temperature differences reduce the effectiveness of the engine by imbalancing the power output of the four pistons.…”

Wind loading on solar concentrators: some general considerations

“…Good annual average insolation is a leading requirement and has been dealt with in detail, e.g., Ref. 27. Of interest herein is the consideration of wind effects, which have received little attention.…”
