Solar panels for schools across Hertfordshire

The school estate in Hertfordshire

Hertfordshire has 382 open state-funded schools and colleges teaching 149,349 pupils, spread across 7 local authorities. Source: DfE Get Information About Schools.

Of those, 296 primary, 61 secondary, 21 special and 4 further education. The phase mix is what sets the usable roof area across a county: secondary sites and colleges carry the sports halls, dining blocks and flat roofs, while primaries offer a hall and a teaching block each and suit arrays sized to the base load.

School rooftop solar and what a Hertfordshire roof models

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 school stands is not what decides the scheme. The timetable is. Source: EU PVGIS v5.2.

Every town page below carries the same arithmetic for that town, including the share of the year that lands in July and August, which is the number a governing body should see before a saving figure.

Solar PV for academy trusts on the Hertfordshire planning record

The Renewable Energy Planning Database records 6 school and college solar schemes in Hertfordshire, across 3 of the towns we cover. They include Samuel Ryder Academy at St Albans, Ridgeway Academy, Herns Lane at Welwyn Garden City and Hockerill Anglo European College, Dunmow Road at Bishop's Stortford. The median array applied for is 195 kWp.

We were not involved in any of those schemes. They are public planning records, and they are here because what a local authority and a network operator have already accepted for one school is the best available guide to what they will accept for the next.

Connections across the county run through UK Power Networks. Anything above 3.68 kW per phase needs a G99 application, and on a school site the incoming supply and the size of the existing main switchboard are often the real constraint rather than the roof.
