Solar panels for schools across Cardiff
We survey school and college roofs throughout Cardiff, model what each one carries against the school's own consumption, and arrange the design, the grid application and the installation through an MCS-certified partner.

School rooftop solar and what a Cardiff roof models
Modelled yield is not flat across Cardiff. Canton comes out at 936 kWh per kWp a year against 908 at Splott, a spread of 28 kWh per kWp. On a 280 kWp school array that difference is about 7,840 kWh a year, which is worth checking before anyone accepts a county-wide saving figure. 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 Cardiff planning record
No school or college solar scheme appears for the Cardiff towns we cover in the Renewable Energy Planning Database. That reflects the reporting threshold rather than an empty county: the database captures generating stations from one megawatt upward reliably, and a school array is a fraction of that. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through National Grid Electricity Distribution. 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.
- Canton 936 kWh/kWp
- Cardiff Bay
- Cardiff City Centre
- Cathays 908 kWh/kWp
- Pontcanna 936 kWh/kWp
- Splott 908 kWh/kWp
Book a roof survey at a Cardiff school
Send the school postcode and the rough roof area, with half hourly meter data if the trust holds it. We come back with what the roofs carry, what they generate against the timetable rather than against an annual average, and how schools pay for it.
Lenzie Consulting Ltd arranges the survey and introduces an MCS-certified installation partner. We do not install, and nothing on this page is a guarantee of a saving.
