In 2015 COFOVO Energy spun out Spectrafy to focus on the SolarSIM business. More information about the SolarSIM products can be found on Spectrafy’s website.
The SolarSIM-D2 represents a bold new approach to solar and atmospheric measurement. It uses simple, rugged hardware and ground-breaking software to accurately resolve full-range and custom range DNI, as well as direct solar spectral irradiance, atmospheric AOD, ozone and precipitable water vapour – all in one small, easy-to-deploy, affordable package.
The SolarSIM-D2 enables this huge leap forward in functionality by deploying silicon photodiodes, coupled with hard-coated optical filters to measure the direct solar spectrum in several narrow wavelength bands. The SolarSIM-D2’s proprietary software then uses these measurements to resolve the complete solar spectrum and DNI, in addition to major atmospheric processes, such as air mass, Rayleigh scattering, aerosol optical depth, ozone-layer thickness and precipitable water vapour.
The SolarSIM-D2 offers ultimate flexibility. It can be deployed with any one or more of its measurement capabilities engaged, and additional capabilities can be added at any point in the future via a simple software upgrade – with no additional hardware required.
The SolarSIM-D2 provides a versatile, low-cost, low-power tool for accurately determining DNI, the direct solar spectrum and major atmospheric constituents for on-site solar resource assessment, meteorological monitoring, PV or CSP performance prediction and weather or climate modelling.
