What the data says about Hertfordshire
Modelled yield is consistent across Hertfordshire, from 895 kWh per kWp a year at Borehamwood to 911 at Bishop's Stortford. At that spread, where the holding sits is not what decides the scheme. Your own demand pattern is.
Across the districts we cover in Hertfordshire the planning record lists 3 ground mounted and 29 roof mounted solar schemes. Ground mounted schemes tell you how the network here has treated field arrays; roof mounted ones are undercounted, because an array on a farm building rarely passes the reporting threshold. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through UK Power Networks. Anything above 3.68 kW per phase needs a G99 application, and on rural feeders the incoming supply is often the real limit: a single phase supply caps the array whatever the roof would carry.
