Optical and solar radiometry standards and traceability
- National Renewable Energy Lab., Golden, CO (United States)
This paper presents an overview of the concept of traceability for optical and solar radiometry measurements, current measurement standards and consensus standards, and measurement uncertainty analysis. The inter-relationships between traceability, standards and uncertainty will be shown. This overview will provide some foundations for other papers in this Workshop. In the late 1970`s, the solar energy research community encountered difficulties when comparing efficiency measurements of flat-plate solar thermal collectors-the efficiency measurements and tests made at participating laboratories revealed differences that were larger than would be expected from the errors believed to be present in the measurement processes used then. The differences were found to be largely due to the solar radiation measurements. There are lessons to be learned from that situation for PV radiometry activities. The concept of traceability and its impact on PV radiometry, is explained and related to standards and calibration, measurement uncertainty analysis, measurement standards, consensus standards, and measurement quality assurance. The concept of traceability and its impact on PV radiometry, is explained and related to standards and calibration, measurement uncertainty analysis, measurement standards, consensus standards, and measurement quality assurance. The measurement reference standards that support the PV optical and solar radiometry will be described. Basic concepts of measurement uncertainty analysis will be highlighted, and extensive references to the literature are given. Consensus standards applicable to PV radiometry work will be noted.
