IEC 62862-5-2 Ed. 1.0 en – Solar thermal electric plants – Part 5-2: Systems and components – General requirements and test methods for large-size linear Fresnel collectors

This part of IEC 62862 specifies the requirements and the test methods for the characterization of a large-size linear Fresnel collector.

This document covers the determination of optical and thermal performance of linear Fresnel collectors, and the tracking accuracy of the collector one-axis tracking system. This test method is for outdoor testing only.

This document applies to linear Fresnel collectors according to Annex A equipped with the manufacturer-supplied sun tracking mechanism.

The testing method in this document does not apply to any collector under operating conditions where phase-change of the fluid occurs. Although the principles of this document can be applied also to collectors with phases-change, however, the sensors (enthalpy, flow, temperatures) required for that are not described in this document.

This document applies to the whole collector field in-situ or as a minimum unit to be tested to an individual collector string (loop) connected to the main piping (flow, return flow) to and from a heat sink, covering the full temperature range of the field.
