You're in good company
Solcast's "Estimated Actuals" closes the gap for our owned and third-party solar portfolios.
Accurate real-time and forecasted weather data is crucial for assessing plant performance and maximizing the value of clean energy assets.
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.
