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 siteshave been analyzed with an innovative specular reflectometer and accelerated aging tests have been carried out in order to estimate the service lifetime. A new accelerated aging procedure is proposed, which consists in combining abrasion and corrosion testing.
