Spectrafy - Model SolarSIM-GPV -Spectral Pyranometer
The SolarSIM-GPV is a Class A pyranometer that also provides the PV professional with everything they need to fully quantify the spectral impact of their solar resource.
The SolarSIM-GPV employs Spectrafy’s patented SolarSIM multi-spectral measurement technology to bring routine solar spectral measurement to the PV industry.
- Measurands: Global solar irradiance (horizontal or tilted), PV spectral correction factors
- Technology: Software-augmented multi-filter radiometer.
- Highlights: Broadband irradiance and spectral correction factors in a single sensor. Makes spectrally corrected irradiance measurement reliable, routine and affordable for the PV industry.
- ISO9060:2018: Class A, spectrally flat for sunlight, fast-response optional.
PV is inherently spectral. Sunlight is a spectral fuel source and solar panels are spectrally selective, so it makes sense that the sensors used to measure sunlight should be spectral too.
Yet for a longest time, the PV industry has had to rely on spectrally-blind sensors to measure sunlight. This disconnect leads to spectral uncertainty that can exceed 4% on an annual basis and over 20% on an instantaneous basis. As the PV industry continues to rapidly evolve, spectral uncertainty is limiting returns for developers and owners alike.
Enter the SolarSIM-GPV, the next step in pyranometer technology. The SolarSIM-GPV uses multi-spectral measurement technology to make the elimination of spectral uncertainty a reality for the PV industry while also providing the highest quality of Class A solar irradiance data.
The SolarSIM-GPV uses filtered photodiodes to make precise, multi-spectral measurements of the solar spectrum. These measurements are then used to resolve the complete solar spectrum and total irradiance. The spectral data is then automatically distilled into intuitive spectral correction factors that are easily implemented in existing industry software.
This SolarSIM-GPV’s powerful combination of multi-spectral measurement and spectral data processing delivers a powerful new tool for the PV industry and a big step forward for pyranometer technology – a spectral sensor for a spectral industry.
