Abstract

In order to reduce electricity generation costs of concentrating solar power (CSP) technologies, new low-cost reflector materials are being developed. These materials need to withstand difficult outdoor conditions without a significant loss in specular reflectance. In this work, samples of enhanced anodized aluminum reflectors protected by a sol-gel coating exposed at different weathering sites have been analyzed with an innovative specular reflectometer and accelerated aging tests have been carried out in order to estimate the service life time. A new accelerated aging procedure is proposed, which consists in combining abrasion and corrosion testing.
