Specialist solar panels for schools in Attleborough
What decides a solar scheme at a Attleborough 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.

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 Attleborough 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, 13 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.
Attleborough ranks 4 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 NR17
The Renewable Energy Planning Database holds no school scheme for the NR17 postcode district. Read that as a gap in the record, not a gap in the roofs: the database is reliable above one megawatt and thin below it, and a school array is typically a fifth of a megawatt.
Look 13 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 Attleborough generation curve
A Attleborough 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 Attleborough changes that ratio much, but plenty about your own site changes what to do with it.
Daily shape compounds it. A school's load climbs from breakfast club, holds through the teaching day and falls away from about three in the afternoon, while generation is still strong until six in high summer. That is why we size against half hourly meter data rather than against annual consumption: the annual figure hides both problems.
A Attleborough 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 whole argument about term dates and the generation curve on the home page, and what it does to a payback figure under costs.
- generated while the school is open
- generated at a weekend or in the holidays

Breckland schools, phase by phase
Breckland has 65 open state-funded schools and colleges on the DfE register teaching 16,718 pupils between them. Source: DfE Get Information About Schools.
The split is 55 primary, 8 secondary and 2 special, at an average of 257 pupils a site. That is 6.9 primaries for every secondary, which is the ratio that matters for a roof: a primary of a few hundred pupils usually offers a hall roof and one teaching block, while a secondary site carries a sports hall, a dining block and several flat roofs.
If your trust holds several of them, the sequencing question comes before the sizing question. Roof age, covering type and the state of the incoming supply vary block by block across an estate, and that is normally what sets the order of works.
Grid connection through UK Power Networks
Connections around Attleborough are handled by UK Power Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a school uses most of what the roof makes during the working day.
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 Attleborough school
Lenzie Consulting Ltd arranges roof surveys for schools across Norfolk. Send the school postcode and a rough idea of the roof area, and the last twelve months of half hourly meter data if the school holds it. We come back with what the roofs can carry, what they would generate against your own consumption, and the funding routes open to a school.
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.
Attleborough school solar, answered
- Is there enough sun around Attleborough for this to be worth doing?
- The model gives 906 kWh a year for every kWp installed at this latitude, so a 210 kWp array comes out at roughly 190,300 kWh a year before shading. It needs about 624 square metres of clear roof once walkways and rooflight setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Does a Attleborough school waste its generation in August?
- 25.7 percent of the modelled annual output for Attleborough falls in July and August, when the buildings are closed for most of six weeks (EU PVGIS v5.2). It does not go to waste, but it only has three places to go: the base load that runs regardless, such as servers, catering refrigeration and ventilation; storage; or export under an agreement with UK Power Networks. We model all three against your half hourly data before an array is sized.
- Will the network around Attleborough accept the export?
- UK Power Networks is the distribution network operator for Norfolk. Anything above 3.68 kW per phase connects under G99, and the application fixes the export limit. On a school site the incoming supply is often the binding constraint rather than the roof, so we ask that question before anyone sizes an array.
- Is planning permission needed for panels on a school in Attleborough?
- Usually permitted development covers a roof array on a school, with prior approval from Breckland needed above a capacity threshold. A ground mounted array in the grounds is a different question and much more likely to need a full application. We check both before design sign-off.
- How many schools are there around Attleborough?
- Breckland has 65 open state-funded schools and colleges on the DfE register, with 16,718 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.
