Table 1

Detectors used in for each of our 5 data sources.

Dataset	Detector	Accuracy
TGHI	LICOR LI-200 pyranometer	% from LICOR data sheet
NCGHI	Eppley Laboratory, Inc. model precision spectral pyranometers	+3%-4% estimated from calibration documentation
WVGHI	Eppley Laboratory, Inc. model precision spectral pyranometers	At least ±2.5% ( from spec sheet)
NYI	Onset silicon pyranometer model S-LIB-M003	±5% from onset data sheet
NYPVS	Commercial SunPower monitoring equipment of PV power installations	±8% compared to DC rated capacity and ±5% calibrated against NYI data (actual calibration was ±4% but is limited by onset calibration)
