Solcast employs a proprietary PV power model, based on a quadratic PV radiation to power conversion algorithm that is uniquely suited for machine learning applications. We have selected this approach, as our PV power products are designed to benefit from user PV power measurement data, which are uniquely specified for each data product. 

If you'd like to know more about how we approach PV power modelling and where the PV power output estimates in our APIs come from, you can review more detailed information at the following page:
