Cost/performance of solar reflective surfaces for parabolic dish concentrators
Materials for highly reflective surfaces for use in parabolic dish solar concentrators are discussed. Some important factors concerning performance of the mirrors are summarized, and typical costs are treated briefly. Although much of the data given are general and applicable to flat or curved solar reflectors, capital investment cost/performance ratios for various materials are computed specifically for the double curvature parabolic concentrators using a mathematical model. The results are given in terms of initial investment cost for reflective surfaces per thermal kilowatt delivered to the receiver cavity for various operating temperatures from 400 to 1400/sup 0/C. Although second-surface glass mirrors are emphasized, first-surface, chemically brightened and anodized aluminum surfaces as well as second-surface, metallized polymeric films are treated. Conventional glass mirrors have the lowest cost/performance ratios, followed closely by aluminum reflectors. Also, ranges in the data due to uncertainties in cost and mirror reflectance factors are given.
