Thanks for checking out the Solcast API, we're delighted you're looking into what data you can have to 'play' around with.
For 'commercial' users who have just found our API services and want to do some development work against our data, we offer 10 free calls/day via our 'Free' tier offering (more information at: https://solcast.com/pricing/). This also includes an initial budget of 1000 API calls to help get you started.
Can I access more than 10 requests/day under a free account?
No. You'll need to upgrade to a "Paid" tier account.
For example, there are two ways to get more API calls.
First, for each new "Site" that you add in the API Toolkit, you'll get an additional 100 API calls per day. The price for this will depend on how many sites you add to your subscription, which you can review in your account page.
Second, you can use the World Solar Radiation or World PV Power APIs, where you make an initial payment of $370USD/month for the first 10,000 API calls, with the next 10,000 calls costing only ~$20USD each.
Tell me more about my other FREE account options?
We offer free data access for researchers. We also offer free data for hobbyists who have a home PV system and want to build cool things. To access these, you must register as a 'researcher' or 'home PV system' account type upon registration (see reference images and terms below).
