source_notes:
  PV Module: CIGS39017
  Technology: Copper indium gallium selenide
  Construction: Glass front/Tedlar back
  Deployment: Cocoa, FL - January 21, 2011 through March 4, 2012; and  Eugene, OR
    - December 20, 2012 through January 20, 2014
  History: Previously deployed for 14 months in Golden, CO
  Footnotes:
  - 1. Measured with a h.a.l.m. flash solar simulator
  - 2. Because of equipment limitations the maximum temperature for measurements was
    65°C instead of 75°C
  - 3. Measurements for 15°C and irradiances of 400, 600, 800, and 1000 W/m2 were
    not performed because of equipment limitations and infrequent occurrence of those
    conditions at the Cocoa, Eugene, and Golden sites.
  - 4. Raw Isc and Imp data corrected for temperature and irradiance using equation
    1 of  IEC 60891, raw Voc and Vmp corrected for temperature
  - '5. Uncertainty for crystalline silicon modules: Pm = ± 2.8%,  Isc = ± 2.3%, Imp
    = ± 2.3%, Voc = ± 0.3%, Vmp = ± 0.7%'
  - 6. With module open-circuited, preconditioning outdoor irradiance of 5.12 kWh/m2
    starting on 4/17/2014 at 3:32 PM and ending on 4/18/2014 at 12:58 PM
  - 7. With module open-circuited, preconditioning outdoor irradiance of 12.17 kWh/m2
    starting on 4/25/2014 at 4:25 PM and ending on 4/28/2014 at 9:50 AM, of which
    0.9 kWh/m2 received on 4/28/2014
  - 8. At 15°C, measured only with forward I-V curve and not reverse sweep, which
    may have underestimated performance for this module with high capacitance. Only
    forward sweep was used because the module was in a transient state having come
    out of climate chamber and was warming to ambient temperature.
