Spectrafy is proud to announce that our ST-5 Sun Tracker is now available with a shadow disc assembly. The ST-5's shadow disc assembly can be used in conjunction with the SolarSIM-G to enable highly accurate measurements of diffuse horizontal spectral irradiance and DHI. The shadow disc assembly can also be used with third-party pyranometers to enable highly accurate measurements of DHI and meets the requirements for Class A DHI measurement for solar power plant applications.
