To help standardise the approach to validation of GB national PV forecasts, we've developed an open-source validation tool, available to download from GitHub / Docker Hub: github.com/SheffieldSolar/PV-Forecast-Validation. This tool can be used to validate any national PV forecast by comparing the forecasted outturns with the PV_Live outturn estimates. An example report, giving the 2019 performance statistics for our own PV_Forecast service, can be downloaded here.

If you have any questions about the accuracy of this service, please don't hesitate to email the Sheffield Solar team.
