Accurate solar resource data
Solargis data has the best accuracy and reliability amongst available solar databases. This has been confirmed by several independent studies.
See comparisonThe key benefits of choosing Solargis are increased efficiency and productivity in solar energy assessment while significantly reducing the weather-related risks.
Why choose us?
Support from planning to operation
Solargis data are available for past, present, and future time periods. The data are updated in real time. Therefore, we can meet your energy assessment needs from project conception to routine daily management.
High level of detail for improved energy modelling
High resolution data (250 m spatial resolution and subhourly temporal resolution) better represent typical and extreme weather, and improve accuracy of solar energy simulations.
Extensively validated
Up to now, Solargis data has been validated at more than 200 locations, globally and the model validation is systematically expanding. Uncertainty of Solargis data can be easily estimated for different climate regions.
