Accelerated Life Testing of Solar Energy Materials: Case Study of Some SelectiveSolar Absorber Coating Materials for DHW Systems. A Report of Task X Solar Materials Research and Development

摘要

Accelerated life testing offers the possibility to forecast material service lifeprior to installation. For the development of new components and systems it, thus, opens a possibility for systematic life cost analysis and material selection. The present report documents the results of a joint study aimed at establishing the use and limitations of methods for accelerated life testing applicable to materials used in solar heating and cooling applications. The study was conducted as part of the work in Task X 'Solar Materials Research and Development' of the International Energy Agency Solar Heating and Cooling Program. The work was organized as a case study in which four commercially-available selective absorber materials were selected for study. These materials are used in single-glazed flat plate solar collectors for domestic hot water production.
