Specialist solar panels for schools in King's Lynn
A school roof in King's Lynn makes 6.2 times as much in June as it does in December, and the school year runs against that curve rather than with it. What we come back with is the usable roof area, the modelled output against your meter data, and the routes schools use to pay for it.
807,300 kWh a year, modelled for a 900 kWp array on roughly 2,673 sqm of clear roof. That is 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.
School rooftop solar across Norfolk
A one kilowatt-peak array on a shallow pitched roof in King's Lynn models at 897 kWh a year, from modelled irradiation of 1,147 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the towns we cover, so what decides the scheme is the school's own demand pattern rather than where in the country it stands.
Scaled up, a 900 kWp array, sized to what the nearest school scheme on record applied for, 26 miles away at Ely, models at about 807,300 kWh a year before shading, and needs roughly 2,673 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 205,900 kWh landing in July and August and roughly 38,800 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.
King's Lynn ranks 7 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.
What the planning record shows around King's Lynn
No school or college solar scheme appears in the PE30 postcode district in the Renewable Energy Planning Database. That is a reporting threshold rather than a verdict. The database records generating stations from one megawatt upward reliably and smaller ones patchily, and almost every school array is a fraction of that, so a roof full of panels on a King's Lynn secondary could be generating today without ever reaching it.
The nearest education scheme on the record is 26 miles from King's Lynn, at Ely: 900 kWp at The Harbour School, Station Road, applicant Cambridge Meridian Academies Trust, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Cambridgeshire planning has already accepted at an education site.

The summer holiday problem for a King's Lynn school
25.5 percent of the annual output modelled for King's Lynn arrives in the two months a school uses least (EU PVGIS v5.2). Term ends in the third week of July and the buildings stay largely empty until September. 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.
The inverse holds at the other end. December and January together return only 4.8 percent of the year, and those are the months with the heating, the lighting and the full timetable all running at once. The roof makes 6.2 times as much in June as it does in December, and August alone outproduces December by about 5.3 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 King's Lynn changes that ratio much, but plenty about your own site changes what to do with it.
Inside the day it happens again. The roof is still at three quarters of its peak at four in the afternoon, by which time a King's Lynn school is largely empty, so the hours that look best on a generation chart are the worst on a consumption one.
A King's Lynn 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

How many schools King's Lynn and West Norfolk has
King's Lynn and West Norfolk has 78 open state-funded schools and colleges on the DfE register teaching 18,895 pupils between them. Source: DfE Get Information About Schools.
The split is 67 primary, 8 secondary, 2 special and 1 further education, at an average of 242 pupils a site. Read 8.4 primaries per secondary as a sequencing hint rather than a statistic. A primary is a single survey visit and a modest array; a secondary is several roofs of different ages on one site, and that is where both the area and the complications are.
A trust holding more than one of these sites should look at them together. Grouping the surveys turns the grid question, the funding question and the procurement route into one exercise rather than four, and it usually changes which roof goes first.
Grid connection through UK Power Networks
UK Power Networks is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Norfolk the planning database records 179 solar schemes totalling 1490 MW, of which 43 are operational (REPD Q1 2026).
Start with the King's Lynn roof
A survey in King's Lynn starts with three things from you. Give us the postcode, the approximate roof area and, if you can get it from your supplier, twelve months of half hourly readings. What comes back is a usable area figure per block, output modelled against your own load rather than an average, and the ways a King's Lynn school can pay for it.
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.
Questions governors ask us about King's Lynn schools
- What would a 900 kWp array produce at a King's Lynn school?
- Yes, and the figure matters more than the sunshine. 897 kWh per kWp a year puts a 900 kWp array at around 807,300 kWh, on roughly 2,673 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 King's Lynn?
- Less is wasted than governors expect, but the figure is worth seeing: 25.5 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 King's Lynn?
- 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 King's Lynn and West Norfolk?
- 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 King's Lynn and West Norfolk. We confirm it either way.
- How many schools are there around King's Lynn?
- King's Lynn and West Norfolk has 78 open state-funded schools and colleges on the DfE register, with 18,895 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.
