- The protocol for optical and geometrical characterization of heliostats focuses on Concentrating Solar Power (CSP) technologies, also known as Solar Thermal Electricity (STE). Power tower or central receiver systems use 2-axis tracking mirrors, so called heliostats, which reflect and focus the sunlight onto a receiver on top of a tower during the day. The protocol is directed to heliostats of CSP central receiver systems. It focuses on the definition of parameters and performance testing of single heliostats during a limited time period. It contains a concisely defined parameter list to describe heliostats and their performance. Measurement techniques or other techniques to derive the heliostat parameters are suggested. The objective of this protocol is to serve as a commonly agreed protocol between R&D centers and industry in the field of heliostat performance testing. The application of this protocol will result in homogenized content of heliostat test certificates which are issued by the different qualification centers. Consequently, bankability of new heliostats should be facilitated. The objective of performance testing of different heliostats according to protocols is to assess heliostat performance on an objective, scientific, but practical level. The report will serve as input for the “SolarPACES Guideline for Heliostat Performance Testing” which will be published during the course of 2018 on www.solarpaces.org under Task III. From the time of publication as SolarPACES Guideline on, users should not refer to this deliverable report, but to the more actual SolarPACES guideline and the respective scientific publication. The publication as SolarPACES guideline shall be the basis for international standards (e.g. IEC) and should be used by national organizations like DKE, AENOR, ASME, ASTM and international organizations for this purpose. The contributions of both researchers and industrial professionals from all over the world to this protocol is gratefully acknowledged.
