Solcast Historical Time Series

Modelling global cloud cover on a 1-2km scale using Solcast's industry leading radiation model.

High resolution and low uncertainty historical Time Series and TMY data for energy simulations and bankable solar resource assessments. Ready to integrate via API.

Detailed global satellite observations that capture cloud cover with precision

The radiation is modelled at the 90m resolution using a terrain grid, to render a precise and accurate global snapshot of historic solar irradiance.

Historic Time Series data can be used to generate large scale historic irradiance analysis like below. We’ve averaged irradiance recieved in February for all of europe and compared that to February 2023.
