DR03 is a high-accuracy direct (normal incidence) solar radiation sensor with a short response time and a relatively small size. The scientific name of this instrument is pyrheliometer. DR03 complies with the first class specifications of the ISO 9060 standard and the WMO Guide. Its fast response time makes DR03 very suitable for PV-related applications. This pyrheliometer has a heated window and is used in tracker-mounted operation. DR03’s compact size improves compatibility with small-sized trackers.
