What our customers say



Adding Solcast's weather data in our hydrogen storage systems improved our control strategy that responds well to weather patterns.

Meinhard Ploner

GKN Hydrogen

Forecasts are crucial in optimizing renewable power plants with predictive controls. Solcast’s forecasts, and the resulting decisions we make with them, are front and center for our operators.

Stephen Schneider

Wärtsilä

On top of our sophisticated solar modelling, Solcast's accurate data has elevated what we already have and allowed us to expand to new geographies.

Rachel Liddell

Aurora Solar

Accurate real-time and forecasted weather data is crucial for assessing plant performance and maximizing the value of clean energy assets.

Taylor Grafton

Also Energy

Solcast's "Estimated Actuals" closes the gap for our owned and third-party solar portfolios.

Cypress Creek Renewables

As far as we know, there's no provider that can provide a more accurate forecast.

Solar data services… in the cloud

We built a new approach to solar forecasting and modeling technology from the ground up, using the latest in weather satellite imagery, machine learning, computer vision and big databases. We crunch more than 600 million new forecasts every hour in a cloud-based environment on AWS and provide real-time access to our data via API. Use the API Toolkit to access nearly 20 years of historical data, including TMY files.
