1 | BMS | | Direct DR02 | 09/29/2023 | 12:40:00 | 09/29/2023 | 13:55:00 | Due to an NREL-wide power outage caused by Xcel Energy, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. |
2 | BMS | | Direct DR02 | 12/01/2022 | 12:08:00 | 12/01/2022 | 13:01:00 | Due to BMS middle sci-tec backup battery replacement (which requires soldering), The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. However automatic substitution was enabled for the CHP1-2, SR25, and CM22-1. |
3 | BMS | | Direct DR02 | 11/22/2022 | 00:00:00 | 11/23/2022 | 23:59:00 | Due to BMS middle sci-tec failure, The following BMS instruments were not exactly pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were just barely shaded: Diffuse SR25, CM22-1, CG4. On 11/23/2022, 11/22/2022 data for CHP1-2, NIP, SR25, and CM22-1 were replaced with primary measurements from south tracker. Note that data on 11/23/2022 were automatically substituded at the logger during middle tracker replacement. |
4 | BMS | | Direct DR02 | 08/22/2022 | 00:00:00 | 08/25/2022 | 08:03:00 | Due to BMS middle sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. However automatic substitution was enabled for the CHP1-2, NIP, SR25, and CM22-1. |
5 | BMS | | Direct DR02 | 08/21/2022 | 00:00:00 | 08/21/2022 | 23:59:00 | Due to BMS middle sci-tec failure, The following BMS instruments were not pointing at the sun during this time: Direct CHP-2, NIP, DR02, RG780, TWC, LI-201, LI-190; and the following instruments were un-shaded: Diffuse SR25, CM22-1, CG4. On 9/14/2022 data for CHP1-2, NIP, SR25, and CM22-1 were replaced with primary measurements from south tracker (which were also reconstucted). |
6 | BMS | | Direct DR02 | 05/18/2020 | 13:03:00 | 12/15/2021 | 19:31:00 | DATA CORRECTED on 12/17/2021: Irradiances were increased by 0.675% due to revised BORCAL report for all BMS shortwave radiometers calibrated in 2020 and 2021. |
7 | BMS | | Direct DR02 | 03/09/2019 | 08:40:00 | 03/09/2019 | 13:01:00 | Due to a scheduled NREL/SRRL power outage, to install power meters on the SRRL building, The following BMS instruments were not pointing at the sun during this time: Direct NIP, LI-201, LI-190, NIP RG780, TWC, DR02; and the following instruments were un-shaded: CG4. |
8 | BMS | | Direct DR02 | 01/17/2017 | 07:15:00 | 01/17/2017 | 08:56:00 | Due to a tripped GFCI powering the Sci-Tec tracker, The following BMS instruments were not pointing at the sun during this time: Direct CHP1 #2, NIP, DR02, LI-201, LI-190, NIP RG780, TWC; and the following instruments were un-shaded: Diffuse CM22 #1, CMP11, CG4. |
