Solar Resource for DNO Regions

PV Performance data for modelling available generation in Distribution Network Operator areas

The spreadsheets available for download below contain hourly values for 2005-2014 for each of 12 UK Distribution Network Operators for the following parameters: Air Temperature deg.C., Global Horizontal Irradiance (G0) Wh/m^2, In-plane irradiance (due south, 22 deg. Tilt) G.POA Whm^2, Module Temperature deg. C. (Tmod), kWh/kWp. Installed Capacity of Solar Farms 2015 (MWelec) and Overallenergy MWh.
