FREE solar irradiance data for your research project

At Solcast, our mission is to enable you to complete yours.  As a researcher, we’ll provide you with access to our Recent and Historical solar irradiance data for non-commercial research use.

How do you get your FREE solar radiation data?

To take advantage of this offer, you have two options.

  1. Register for the Solcast API service using your University email address and get $400 of historical data credits.

  2. Provide a link from your University and/or project webpage back to Solcast using the anchor text “solar irradiance data” and get $2500 of historical data credits.

Historical data extracts are $100/year/site and include all the solar and weather parameters covered on our pricing page. Data are available at 5/10/15/30/60 minute resolution, for up to 12 years.

Additional requirements of this offer include:

  • You share us preprints of your publications or thesis (we want to see what awesome work you did!)

  • You only use our data for non-commercial research use, and you don’t share our data with any third parties without our explicit written permission

  • You don’t do or publish anything that could be reasonably expected to cause damage or harm to Solcast’s reputation

Need even more free data?

If you need data for new sites, or for many sites, talk to us about options. Don’t worry, even if it’s significant work for us, we’ll only make a cost proposal to you based on cost recovery for our time at cost.

That’s it! If you have any further questions, hit us up on the chat bubble at bottom right!
