Solcast has just announced an official version 1 (v1.0) for our API services.  In v1.0 we have employed a ‘sites’ based approach where each has a unique resource ID based on a single, set location.  

This API can provide both forecasts and estimates of the actual power output (estimated actuals) from solar PV systems of both rooftop (<1MW) or utility scale (>1MW) . 

This sites-based framework also allows Solcast to provide real-time reporting on forecast accuracy, so that you can track our performance and validate our product with ease.  We even persist our 1-hour ahead forecast in the API to make it easy for you to validate our accuracy on-the-fly. 

Lastly, before we get started, do us a favour - if you find any errors, or something is unclear, or just have some helpful feedback, please let us know at
