Subject: | SGP/SIRS/E21 - Shadowband Misalignment |
DataStreams: | sgpsirsE21.00, sgpsirsE21.b1, sgpsirs20sE21.a0 |
Description: | Solar tracker stopped functioning on 7/17. Tracker power cycled on 07/24 and returned to normal tracking but failed again 7/25. Power was cycled again 8/6 and tracker performance was sustained thereafter. |
Suggestions: | Affected downwelling diffuse (DD) and direct normal (NIP) data is not recoverable. Downwelling IR (DIR) data should be used with the knowledge that the pyrgeometer is not shaded during this period. |
