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, location is not what decides your payback here. Your consumption pattern is.
The larger roofs in Hertfordshire follow the freight routes. Across the towns we cover that means M1 J5, M25 J19, M25 J20, A41, M1 J8 and M1 J9, which is where single-let distribution stock concentrates.
The government's planning database records 119 solar schemes in Hertfordshire totalling 844 MW, of which 12 are already operational and 29 of the schemes in our covered postcode districts are roof mounted. 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 the export limit they offer shapes the design, so we ask the question before the array is sized rather than after.
