The industry standard instrument to measure solar radiation is a class-A pyranometer. However, physical sensors require regular maintenance and calibration and can experience downtime that leads to data gaps. In 2023, DNV published a bankability study validated Solcast’s satellite-based irradiance data with measurements from Class A pyranometers cleaned at least bi-weekly. Combining measurement’s with a high-quality satellite irradiance data source, like Solcast, more accurate, reliable solar irradiance data for your assets, especially when using measurements for a fleet of assets. .
