1. Outdoor solar measurement comparison
Two SpectroSolar units were taken to Davos, Switzerland, at the PMOD/WRD (Physikalisch-Meteorologisches Observatorium Davos, World Radiation Center) during the 11th International Pyrheliometer Comparisons (IPC-XI).
Solar irradiance measured with our SpectroSolar units has been compared to data recorded by a scanning double-monochromator (Optronic Laboratories, Inc. The OL Series 750). Both the SpactroSolar units and the double-monochromator were mounted on sun-trackers.
Data from our SpectroSolar units, with 1ms integration time, is compared to measurements by the double-monochromator is presented in Figure 2.
Note that the SpectroSolar optical resolution (5nm) is slightly higher than the resolution of the double-monochromator. Differences in relative energy, integrated over 50nm bands, are below 3%.
2. Measurement of pulsed-type solar simulators
The SpectroSolar has been designed with special emphasis on measuring pulse-type solar simulators. It is capable of measuring the relative irradiance of short-pulsed solar simulators in 1ms exposure time. Figure 3 shows data recorded by the SpectroSolar on two different pulsed solar simulators. This data was recorded with an integration (exposure) time of 1ms, and using a delay of 4ms between the trigger signal
generated by the integrated photocell and the start of the exposure
The international norm IEC 609604-9 for solar simulators classifies solar simulators (class A, B or C) according to the their specral-match to sunlight at Air Mass 1.5 Global as defined in IEC 60904-3. For 6 wavelength intervals of interest, the fraction of energy measured on the simulator is compared to this “standardized” solar energy distribution. A value of 100% means that the fraction of energy produced by the solar simulator exactly corresponds to the energy fraction specified for that band in the IEC 609604-9 norm. “Class A” requires that the energy fraction lies between 75 and 125% of the standard value for all wavelength intervals.

In this example, both solar simulators produce a spectral-match of Class A, because the all wavelength intervals have energy fractions lying between 75 and 125% of the IEC 609604-9 norm. The software included with the SpectroSolar automatically makes these calculations, thus results are immediately available after the measurement!
