Abstract
Measured solar radiation resource data are needed by electric utilities to evaluate the potential of renewable energy options like photovoltaics in their service territory. In this final test report, we document a cooperative project of the Electric Power Research Institute (EPRn and the National Renewable Energy Laboratory (NREL) to compare available measurement system options for performingsolar radiation resource assessments. We present the detailed results of a 6-month field comparison of thermopile-based pyranometer and pyrheliometer solar irradiance measurement systems with two different implementations of the rotating shadowband radiometer (RSR) concept installed at NREL's Solar Radiation Research Laboratory (SRRL) in Golden, Colorado.
