Solar Radiation Data (Product Page)

Real-time and forecast solar radiation data, worldwide via API
Using our proprietary cloud detection, aerosol tracking and prediction algorithms, we provide real-time and forecast availability of solar radiation around the world.

The data is updated every 5-15 minutes with each new satellite image, and instantly made available via our API services. Our live solar radiation data is available from real-time back through 7 days, and our forecast data extends out to 7 days ahead.

Access to Our Solar Radiation Data
We offer three different ways to access live and forecast solar radiation data, and each are powered by the same Rapid Update cloud tracking and prediction system.

1. Solar Radiation Sites

For users who have an application with fixed locations, using the Sites API is best. This API comes with the added benefit of built-in accuracy assessment tools, and the ability to be linked to another site (e.g. a collocated Utility Scale site). Upon registration for the API Toolkit, your first Solar Radiation site is free.

Pricing starts at $50USD/month/site, with discounts applied for more than five sites.

2. Solar Radiation Sites (5, 10, and 15 minute resolution data)

For users who have who have fixed locations, and also require higher time resolution data, you can access 5, 10 or 15 minute time resolution at $99USD/month/site, with discounts applied for more than five sites. This data becomes available through the creation of a Utility Scale site in the API Toolkit

3. World Solar Radiation API

Instantly retrieve live or forecast data from anywhere in the world at 30-minute resolution using latitude and longitude. The World Solar Radiation API is best suited for users who need data from many locations or whose area of interest in continually changing (e.g. solar car), and who do not require high time resolution. This API still receives Rapid Update service, with new data flowing into the API with every satellite scan. Register for the API Toolkit and you’ll receive 1000 API calls to get started.

Pricing for the World Solar Radiation API starts at $370USD/per month for 10,000 API calls with each additional 10,000 API calls.
