Techniques for Supplementing Solar Radiation Network Data, Volumes 1-3

September 1992

A. Zelenka, et al.
Swiss Meteorological Institute

Report #IEA-SHCP-9D-1.

Solar radiation data is required for resource assessment, simulation model development and validation, system design and evaluation, collector testing, and other activities in the field of solar energy research and application. And, spatially continuous mapping of solar radiation is needed to properly obtain this data. This report focuses on techniques for estimating solar radiation received on the earth's surface at locations between network sites, using both measured and modeled data.

IEA Comparisons of Global Solar Radiation Reference Radiometers

March 1995

L. Liedquist, et al.
Swedish National Testing and Research Institute

Report #IEA-SHCP-9F-4.

In solar energy research the ability to accurately measure the incoming solar irradiance level is important. This report presents the findings from two studies which compared three reference instruments to verify the 1% uncertainty and also to assess the state-of-the-art.

Using Pyranometers in Tests of Solar Energy Convertors: Step-by-step Instructions

November 1995

L.B.J. McArthur, et al.
Atmospheric Environment Service, Canada

This report offers a step-by-step guide to the measurement of global solar radiation for the purpose of determining the efficiency of flat plate solar collectors. Comprehensive instructions are provided for each stage of the procedure, including where to obtain instrument responsivities and how to install and operate pyranometers and their data acquisition systems. It is assumed the reader has some technical expertise in collector installation and operations, but not necessarily familiar with the measurement of solar radiation.

Improved Measurement of Solar Irradiance by Means of Detailed Pyranometer Characterisation

April 1996

D.I. Wardle, et al.
Atmospheric Environment Service, Canada

Report #IEA-SHCP-9C-2.

The focus of the work is on determining the effects of factors other than irradiance on the signals from pyranometers, which is the meaning of characterisation in the context of pyranometery. Results from eleven laboratories on nearly thirty pyranometers of seven types have been examined.
