Solcast is providing Free Access to Solar Irradiance Historical Data for Researchers and Students
Join researchers from around the world in using Solcast data to accomplish their solar mission & build the solar powered future
As a university researcher or student, when it comes accessing solar irradiance data for your academic research, it can be quite hard to obtain the right datasets to complete your work.
Paid datasets are prohibitively expensive and require grant funds to purchase them, which isn’t a great option for PhD students or graduates, nor for academics looking to establish proof of concept for a bigger idea.
Free data are often not maintained, scattered about and lack supporting information. Moreover, they can be of questionable quality and no one is around to answer your questions when you get stumped!
Our mission is to enable you to build the solar powered future
At Solcast, our purposes is to enable hard working people all around the world with the data and tools they need to accomplish their solar mission. In our view, this type of enablement is critical for building the solar powered future, now arriving more quickly than ever before!
The challenges of accessing solar radiation data are particularly problematic for the researchers who want to contribute to the incredible transformation occurring in our electricity sector, as their efforts will inherently require access to solar radiation and/or solar power generation data, at high spatial and temporal resolutions. But, up to now, those datasets have missed the mark. Either they are outdated, lack support or cost too much!
FREE solar irradiance data for your research project
We’ve aimed our resources directly at this problem, and want to give you the data you need for FREE (no cash required!). 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.
Register for the Solcast API service using your University email address and get $250 of historical data credits.
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 $50/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 15 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 will create a proposal for you based solely on cost recovery.
Get started on your FREE data access
Very soon, we’ll offer an automated tool for retrieving your data and being issued your credits. Until then, there are a few things you need to do:
- Contact our CTO (Nick) via the chat bubble at the bottom right of this page.
- Confirm that you agree to the above terms; and raise any limitations you have on complying with them
- Let us know what research institute you are working/studying at
- Provide a list of latitude & longitude locations for your historical data (if applicable)
- Let us know what data types you require and the time period being requested
- And be sure to visit the registration page so you can get started (NOTE: we recommend using your .edu email address so we can confirm your research status straight away)!
