Is the SolarSIM-GPV an ISO9060:2018 Class A pyranometer?
Yes, the SolarSIM-GPV is fully compliant with ISO9060:2018 Class A instrument performance criteria. In addition, ISO9060:2018 specifies sub-classifications of 'spectrally flat' and 'fast response'. The SolarSIM-GPV is spectrally flat for sunlight and a 'fast response' version of the SolarSIM-GPV is available as an option. The SolarSIM-GPV is the only Class A pyranometer that is able to accurately resolve both broadband irradiance and PV spectral correction factors.
