What is HowMuchSun
Real-time solar irradiance
forecasts for smarter decisions
HowMuchSun provides real-time solar irradiance forecasts powered by satellite data and advanced modelling, calibrated by ground sensors. Whether you manage a solar farm or trade energy, we deliver precise solar potential insights up to 6 hours ahead.
Global Climate Expertise
Powered by world-class science
Our service is developed with support from the European Centre for Medium-Range Weather Forecasts (ECMWF) and powered by the Copernicus Atmosphere Monitoring Service (CAMS) and the Copernicus Climate Change Service (C3S).
This means your solar forecasts are backed by the same trusted science and infrastructure used by governments, researchers, and energy operators worldwide.
Pilot Project
Piloting at one of the world’s largest solar parks
HowMuchSun is being piloted at Benban Solar Park in Egypt, a 1.8 GW complex covering 37 km² in the Aswan desert.
Benban is one of the largest solar installations in the world, producing enough electricity to power hundreds of thousands of homes.
