Specialist solar panels for schools in Wymondham
What decides a solar scheme at a Wymondham school is how much of the output the site uses itself, not how much the roof makes. We arrange the roof survey, model the output against the school's own half hourly consumption, and set out the funding routes.
25.7% of the modelled year lands in July and August, on a roof that returns 906 kWh per kWp a year. The worked example below runs at 210 kWp, the size applied for at the nearest school scheme on record. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Illustrative layout for an estate of this size. The array is drawn at about 345 kWp, roughly 53 percent of the 650 kWp these three roofs would hold, because a school sizes to the load it can use in term time rather than to the roof it has: generation it cannot use is exported at a much lower rate than it pays to import. The hatched block carries no array because its structure has not been assessed, which on a school of that era is the usual starting point rather than an exception. Your own figures, and which of your blocks can take an array, come from the roof survey.
Solar for education buildings across Norfolk
A one kilowatt-peak array on a shallow pitched roof in Wymondham models at 906 kWh a year, from modelled irradiation of 1,160 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is roughly 2 percent above the mean across the towns we cover, so latitude is working slightly in your favour here.
Scaled up, a 210 kWp array, sized to what the nearest school scheme on record applied for, 19 miles away at Thetford, models at about 190,300 kWh a year before shading, and needs roughly 624 square metres of clear roof. We take the size from the nearest real application rather than a round number, so the example is anchored to something a planning officer has already seen.
Spread across the year that is about 48,900 kWh landing in July and August and roughly 9,300 kWh across December and January. UK Power Networks sets what may go back onto the network here, so the July figure is the one worth putting in front of a governing body first.
Wymondham ranks 3 of 8 towns we cover in Norfolk on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 897 to 923, a spread of 26 kWh per kWp. Within Norfolk that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
School solar on record near NR18
Search the Renewable Energy Planning Database for the NR18 postcode district and nothing comes back under education. That is worth stating plainly and then setting aside: the register is built around generating stations, a school array is a fraction of the size it captures reliably, and plenty of school roofs never appear in any national record at all.
Look 19 miles out and there is one: The Bishops CE Primary Academy in Thetford, 210 kWp, applied for by Solar Options for Schools Limited, which holds consent and is awaiting construction. None of our doing. It is a public planning record, and the nearest evidence available of how an application like yours is treated around here. Source: Renewable Energy Planning Database, Q1 2026.
Term dates against the Wymondham generation curve
A Wymondham school roof generates most in the weeks its buildings are closed. 25.7 percent of the modelled year lands in July and August alone (EU PVGIS v5.2), and the summer holiday takes roughly six of those nine weeks out of the timetable. July is the single strongest month here at 13.8 percent of the annual total, and it falls almost entirely inside the holiday.
Winter reverses it. December and January between them return 4.9 percent of the modelled year, and that is when the heating, the lighting and a full register are all drawing at the same time. The roof makes 6.3 times as much in July as it does in December, and August alone outproduces December by about 5.4 to one. 74 percent of the year arrives between April and September, and the point of that figure is not that the summer half goes unused, because April, May and June are full teaching months that draw hard. It is that the concentration peaks in the few weeks at the end of it when the building is shut.
Summed over the year, about 49 percent of what a school roof makes arrives while the school is open. For a business trading every weekday the equivalent is roughly 71 percent. Nothing about Wymondham changes that ratio much, but plenty about your own site changes what to do with it.
Then there is the afternoon. From roughly three o'clock the building empties while the roof is still working, so a system sized on annual consumption will over-generate in exactly the hours nobody is there. We size on half hourly data for that reason.
A Wymondham governing body should read that as a sizing constraint, not a reason to stop. The base load that runs through the holidays, servers, comms, refrigeration, ventilation and hot water, is the floor the array should be built up from, and everything above it has to be justified by storage, export or summer occupancy.
We set out the full treatment of the school year against the generation curve on the home page, and what it does to a payback figure under costs.

South Norfolk schools, phase by phase
South Norfolk has 74 open state-funded schools and colleges on the DfE register teaching 20,376 pupils between them. Source: DfE Get Information About Schools.
The split is 64 primary, 9 secondary and 1 special, at an average of 275 pupils a site. 7.1 primaries per secondary is a mix weighted towards small sites. The roof area, and therefore most of the generation, sits with the 9 secondaries.
Across an estate of that size the roofs will not be in the same condition, and that is the point of surveying them together: the block with the best orientation is often not the block whose covering has twenty years left in it.
Grid connection through UK Power Networks
UK Power Networks operates the distribution network across Norfolk, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.
Across Norfolk the planning database records 179 solar schemes totalling 1490 MW, of which 43 are operational (REPD Q1 2026).
Book a roof survey at your Wymondham school
The first survey answers three questions at once: what the roofs carry, what they generate against your own timetable, and how a Wymondham school pays for it. Send the postcode, an approximate roof area per block and half hourly meter data if the school can get it from its supplier.
Lenzie Consulting Ltd arranges the survey and passes your details to an MCS-certified installation partner so they can quote. We do not carry out the installation ourselves.
Wymondham school solar, answered
- How much would a school roof near Wymondham generate?
- Modelled at 906 kWh per kWp a year, a 210 kWp array on a Wymondham school models at about 190,300 kWh. What decides whether that is worth doing is how much of it the school uses itself, not the total. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- How does the school year affect a solar scheme in Wymondham?
- It goes somewhere, just not into the timetable. 25.7 percent of the Wymondham generating year lands in July and August (EU PVGIS v5.2), and a closed school still runs servers, comms, refrigeration and ventilation. What that base load does not absorb is either stored, exported under an agreement with UK Power Networks, or a sign the array is too big. We test which before sizing anything.
- Which network operator handles the connection at a Wymondham school?
- Applications go to UK Power Networks, who run the network across Norfolk. An export-limited offer usually still works for a school, because the summer surplus is the part you were least likely to be paid much for anyway.
- What does South Norfolk require for solar on a school building?
- Roof-mounted solar on a non-domestic building often falls within permitted development under Part 14 of the General Permitted Development Order, subject to limits on how far the panels stand proud of the roof plane and, above a threshold, to prior approval from South Norfolk on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to South Norfolk before a design is finalised.
- How many schools are there around Wymondham?
- South Norfolk has 74 open state-funded schools and colleges on the DfE register, with 20,376 pupils on roll. Source: DfE Get Information About Schools. We survey across the whole of that area, and where a trust holds several sites we look at them in one pass.
