The SR-1901PT is designed  for validating the output of pulsed solar simulators. The system is
especially well-suited for testing the power ratings of photovoltaic modules and solar panels. All
systems come with the subroutines necessary to generate high quality solar spectra and
spectral matching reports.
Solar module and panel manufacturers must ensure that their
products meet promised power and performance levels. To
ensure this, they use solar simulators to reproduce outdoor
Solar simulators come in two flavors: continuous or pulsed.
Pulsed simulators (long and short) are less expensive and easier
to use and are growing in popularity. All solar simulators are
classified as Class A, Class B, or Class C depending on the
standards they meet for spectral match to sunlight, uniformity of
the light source, and stability of the light source over time.

SPECTRAL EVOLUTION provides the
SR-1901PT portable
spectroradiometer for testing and classifying long and short
pulse solar simulators for spectral match to AM0 and AM1.5 and
for uniformity and stability measurements.

The SR-1901PT captures the full spectrum from 280-1900nm in a
single flash with a 1 msec integration time. This allows for
spectral matching for short and long pulse simulators in a
fraction of the time it would typically take - seconds instead of
hours.

The SR-1901PT includes our DARWin SP Data Acquisition
software with spectral matching report capabilities to quickly
verify if your simulator meets the appropriate ratings for each
wavelength band.

In addition, it includes NIST-traceable irradiance calibration, 1.2
meter dual fiber optic with a custom diffuser and built-in
phototrigger, 100-240 volt/50-60Hz power supply, and a
dust-proof and waterproof foam-line Pelican case for shipping.
The SR-1901PT is portable so you can use it wherever you need
to test your solar simulator.;

Solar simulators can provide an accepted method for measuring and testing the power ratings of
photovoltaic modules and solar panels at the manufacturer's facility. Uncertainties in the validity of these
measurements can significantly impact a manufacturer's revenue. DARWin SP Data Acquisition software
provided as a function of wavelength and generates a spectral match report to provide confidence in the
output of the pulsed solar simulator in use.
