Abstract: The data of four sets of the sun radiation testing system in Hohhot was processed by the method of standard deviation to get the highest relative accuracy as a model with data. By comparing the measuring value with the calculating value of clear-sky solar radiation model established, it is found the model is only fit for the sunny day, moreover the lager percentage of sunshine is, the model is more appropriate. This model can meet the practical needs of general engineering and also can be used in the analysis of building energy efficiency

Abstract: The solar thermal collector performance evaluation system is designed for the actual needs of tests for industrial production and scientific research, which is adequate for stable efficiency, time constant, incident angle modifier and pressure drop measurement on either end of the thermal collector.
