Specialist solar panels for schools in Thetford
A 210 kWp array at The Bishops CE Primary Academy is the nearest school scheme on the planning record, and it holds consent and is awaiting construction. We arrange the roof survey, model the output against the school's own half hourly consumption, and set out the funding routes.
897 kWh per kWp a year at this latitude, so a 210 kWp array, the median size schools around Thetford have applied for, models at about 188,400 kWh. 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.
Which schools around IP24 have applied
The Renewable Energy Planning Database records 1 school and college solar scheme in the IP24 postcode district. A primary school, The Bishops CE Primary Academy, applied for 210 kWp roof mounted and the scheme holds consent and is awaiting construction. The applicant on record is Solar Options for Schools Limited.
None of these are ours. They are entries in the public planning record, reproduced here because a consented array at a school down the road is a better guide to your own prospects than any national average. Source: Renewable Energy Planning Database, Q1 2026.
One thing to be clear about: the drawing at the head of this page is an illustrative estate, not The Bishops CE Primary Academy and not a survey of anyone's roof. What we know about the scheme above is only what the public planning record says.
The median array applied for here is 210 kWp. At 210 kWp you are covering roughly 624 square metres of roof once walkways, edge zones and rooflight setbacks come out, which on most sites means a sports hall plus one teaching block rather than the whole estate.
Every one of them is a primary school, which is worth knowing: a primary site has less roof and a smaller daytime load, so the schemes that clear planning there are the ones sized to the base load rather than to the available slope.

Solar for education buildings across Norfolk
A one kilowatt-peak array on a shallow pitched roof in Thetford models at 897 kWh a year, from modelled irradiation of 1,150 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). Against a mean of 886 kWh per kWp across the towns we cover, Thetford is unremarkable, which is the useful finding: the scheme will be decided by the load curve, not the map.
Scaled up, a 210 kWp array, sized to the median array applied for at schools around Thetford itself, models at about 188,400 kWh a year before shading, and needs roughly 624 square metres of clear roof. That size is not one we chose. It is what schools in this district have actually applied for.
Spread across the year that is about 48,200 kWh landing in July and August and roughly 9,400 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.
Thetford ranks 8 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.
Term dates against the Thetford generation curve
A Thetford school roof generates most in the weeks its buildings are closed. 25.6 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. June is the strongest single month here at 13.7 percent of the annual total, which is still term time, and that works slightly in your favour against towns whose curve peaks in July.
Winter reverses it. December and January between them return 5 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 5.9 times as much in June as it does in December, and August alone outproduces December by about 5.1 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.
Nationally this comes out at about 49 percent of annual generation falling on a session day. A business open every weekday sees roughly 71 percent. The 22 point gap is what a school appraisal has to absorb, and it is much the same in Thetford as anywhere else.
The weekly pattern repeats the annual one. Saturdays and Sundays generate as well as any other day and consume almost nothing, so before storage or export is even discussed it is worth knowing what the site does at a weekend, which only half hourly data will tell you.
The conclusion is not that a Thetford school should do nothing. It is that the array should be sized to the load that survives the holidays, which is usually the server room, the catering refrigeration, the ventilation and the hot water, plus whatever the site lets out over the summer. Anything above that line needs storage or an export agreement with UK Power Networks to earn its keep.

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
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).

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.
Thetford school solar, answered
- What would a 210 kWp array produce at a Thetford school?
- Yes, and the figure matters more than the sunshine. 897 kWh per kWp a year puts a 210 kWp array at around 188,400 kWh, on roughly 624 square metres of roof. The value of that depends on your term time load. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- What happens to the electricity during the summer holidays in Thetford?
- Less is wasted than governors expect, but the figure is worth seeing: 25.6 percent of the year is modelled to arrive in July and August here (EU PVGIS v5.2), against a site running on holiday base load. Lettings, holiday clubs and summer works take some of it, storage takes more, and the rest is an export question for UK Power Networks.
- Who do we apply to for export near Thetford?
- Only UK Power Networks can answer it for your connection. What we can say is that a capped export limit rarely breaks a school scheme, because the array that suits a school is sized to the term time load rather than to the roof.
- Do we need planning permission in Breckland?
- Often not, because panels on the roof of a school building usually sit within permitted development for non-domestic buildings. The exceptions are listed buildings, conservation areas and arrays that project too far above the roof plane, and larger schemes still need prior approval from Breckland. We confirm it either way.
- Has a school near IP24 already done this?
- One school scheme is on record in this postcode district, including a 210 kWp array at The Bishops CE Primary Academy that holds consent and is awaiting construction. We were not involved in it. It is a public planning record, and it matters less as proof that solar works than as evidence of what this authority and this network operator have already accepted. Source: Renewable Energy Planning Database, Q1 2026.
- How many schools are there around Thetford?
- 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.
