Ground based measurements often have obvious or hidden errors. Use of satellite-derived irradiation data promotes transparency in performance reporting. Besides being independent, Solargis data have comparable accuracy to that of pyranometer measurements for monthly and yearly values.
There are several satellite-derived solar data sources, and they have varying levels of accuracy. Independent validation studies that compare modeled data with high-quality ground observations show that Solargis has in most cases the lowest monthly RMSD and bias accuracy indicators for GHI. Therefore Solargis is the most suitable satellite-derived solar database for PV performance monitoring.

API service allows plugging Solargis data into a monitoring platform of your choice. Majority of them can already ingest Solargis data—you don’t need to do any integration work.
Solargis Monitor not only provides access to solar radiation and air temperature but also simulates PV power production. Thus you can directly compare actual PV power production with expected production for any period of interest.
“We chose Solargis mainly because independent comparisons showed Solargis to be the most accurate irradiation database. We also performed comparisons with our own measurements and saw that claims of Solargis were indeed true – Solargis data matched very well with ground measurements” Anne Laure Bichot, Performance Manager at LightsourceRead full case study
Solargis Monitor can be easily integrated with the following leading monitoring platforms via API/FTP. Full list of integration partners is here.
