Specialist solar panels for schools in Huntingdon
A kilowatt-peak on a Huntingdon school roof models at 908 kWh a year, above the mean across the towns we cover, and the roofs it applies to are mostly carrying nothing. The survey records sheet type, remaining life, purlin spacing and the state of the incoming supply, and the model runs off your own meter data rather than an average.
25.4% of the modelled year lands in July and August, on a roof that returns 908 kWh per kWp a year. The worked example below runs at 1000 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 PV for academy trusts across Cambridgeshire
A one kilowatt-peak array on a shallow pitched roof in Huntingdon models at 908 kWh a year, from modelled irradiation of 1,161 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 1,000 kWp array, sized to what the nearest school scheme on record applied for, 16 miles away at Cambridge, models at about 908,000 kWh a year before shading, and needs roughly 2,970 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 230,600 kWh landing in July and August and roughly 46,300 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.
Huntingdon ranks 1 of 8 towns we cover in Cambridgeshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 898 to 908, a spread of 10 kWh per kWp. Within Cambridgeshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
The planning position for Huntingdon schools
The Renewable Energy Planning Database holds no school scheme for the PE29 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.
The closest recorded one is about 16 miles away at Cambridge: St Bedes Inter-Church School, a 1,000 kWp roof mounted array applied for by Solar Options for Schools, which holds consent and is awaiting construction. We were not involved in it. We cite it because it is a public record of what has cleared planning in this part of Cambridgeshire. Source: Renewable Energy Planning Database, Q1 2026.
Why demand in Huntingdon falls as the roof peaks
The generating year and the school year are out of step in Huntingdon. July and August carry 25.4 percent of the modelled output (EU PVGIS v5.2), and the site is closed for most of those nine weeks. June is the strongest single month here at 13.8 percent of the annual total, which is still term time, and that works slightly in your favour against towns whose curve peaks in July.
At the other end of the year the mismatch flips. Only 5.1 percent of output falls in December and January, the two months when a Huntingdon school is fully occupied and its heating and lighting are at their heaviest. The roof makes 5.7 times as much in June as it does in December, and August alone outproduces December by about 4.8 to one. 73 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 Huntingdon 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 Huntingdon 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.

The school estate in Huntingdonshire
Huntingdonshire has 74 open state-funded schools and colleges on the DfE register teaching 24,299 pupils between them. Source: DfE Get Information About Schools.
The split is 63 primary, 7 secondary and 4 special, at an average of 328 pupils a site. That is 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 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 Cambridgeshire the planning database records 172 solar schemes totalling 2422 MW, of which 46 are operational (REPD Q1 2026).
Send us the school postcode
We survey school and college roofs throughout Cambridgeshire. We need the postcode, a rough roof area and your half hourly meter data if the trust has it. From that we model what the roof carries, what it generates against the timetable, and which of the funding routes actually suits a school of your size.
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.
What Huntingdon trusts ask before a survey
- Is there enough sun around Huntingdon for this to be worth doing?
- The model gives 908 kWh a year for every kWp installed at this latitude, so a 1,000 kWp array comes out at roughly 908,000 kWh a year before shading. It needs about 2,970 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 Huntingdon school waste its generation in August?
- 25.4 percent of the modelled annual output for Huntingdon 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 Huntingdon accept the export?
- UK Power Networks is the distribution network operator for Cambridgeshire. 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 Huntingdon?
- Usually permitted development covers a roof array on a school, with prior approval from Huntingdonshire 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 Huntingdon?
- Huntingdonshire has 74 open state-funded schools and colleges on the DfE register, with 24,299 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.
