The basic objective of the National Solar Data System Accuracy Test was to determine the end-to-end accuracy of the Data System, identify sources of data errors, and determine their contribution to any data collection inaccuracies. The determination of a representative system accuracy was accomplished by taking off the shelf sensors and data components to an independent testing laboratory for installation and operation as a typical National Solar Data Network site. The Data System was tested with controlled input conditions to determine if the data was sensed correctly and processed accurately. The test program was divided into three phases: sensors were individually calibrated, static temperature tests were performed to verify the data path, and dynamic tests were performed to determine the accuracy of system level data collection and processing. The general description of the Data System is provided, the test methods are described and test results presented. Results of a pyranometer verification test is also presented. It is concluded that the Data System provides accurate measurement of system parameters, error free data processing, and accurate performance evaluation. (LEW)
