Specialist solar panels for schools in Wakefield
A school roof in Wakefield makes 6.5 times as much in July 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.
26.2% of the modelled year lands in July and August, on a roof that returns 837 kWh per kWp a year. The worked example below runs at 400 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.

- first phase
- later phase
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 West Yorkshire
A one kilowatt-peak array on a shallow pitched roof in Wakefield models at 837 kWh a year, from modelled irradiation of 1,069 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 6 percent below the mean across the towns we cover, so the case at this latitude rests almost entirely on using the output on site rather than exporting it.
Scaled up, a 400 kWp array, sized to what the nearest school scheme on record applied for, 27 miles away at Ashton-under-Lyne, models at about 334,800 kWh a year before shading, and needs roughly 1,188 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 87,700 kWh landing in July and August and roughly 15,400 kWh across December and January. Northern Powergrid 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.
Wakefield ranks 2 of 8 towns we cover in West Yorkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 811 to 846, a spread of 35 kWh per kWp. Within West Yorkshire 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 Wakefield
The Renewable Energy Planning Database holds no school scheme for the WF1 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 nearest education scheme on the record is 27 miles from Wakefield, at Ashton-under-Lyne: 400 kWp at Tameside College, Beaufort Road, applicant Tameside College, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Greater Manchester planning has already accepted at an education site.

The summer holiday problem for a Wakefield school
26.2 percent of the annual output modelled for Wakefield 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. July is the single strongest month here at 14 percent of the annual total, and it falls almost entirely inside the holiday.
The inverse holds at the other end. December and January together return only 4.6 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 6.5 times as much in July as it does in December, and August alone outproduces December by about 5.7 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 Wakefield as anywhere else.
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 Wakefield school is largely empty, so the hours that look best on a generation chart are the worst on a consumption one.
The conclusion is not that a Wakefield 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 Northern Powergrid to earn its keep.

How many schools Wakefield has
Wakefield has 141 open state-funded schools and colleges on the DfE register teaching 53,330 pupils between them. Source: DfE Get Information About Schools.
The split is 116 primary, 18 secondary, 4 special and 3 further education, at an average of 378 pupils a site. That is 6.4 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 Northern Powergrid
Connections around Wakefield are handled by Northern Powergrid, 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 West Yorkshire the planning database records 170 solar schemes totalling 550 MW, of which 8 are operational (REPD Q1 2026).
Start with the Wakefield roof
The first survey answers three questions at once: what the roofs carry, what they generate against your own timetable, and how a Wakefield 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.
Questions governors ask us about Wakefield schools
- What would a 400 kWp array produce at a Wakefield school?
- Yes, and the figure matters more than the sunshine. 837 kWh per kWp a year puts a 400 kWp array at around 334,800 kWh, on roughly 1,188 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 Wakefield?
- Less is wasted than governors expect, but the figure is worth seeing: 26.2 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 Northern Powergrid.
- Who do we apply to for export near Wakefield?
- Only Northern Powergrid 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 Wakefield?
- 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 Wakefield. We confirm it either way.
- How many schools are there around Wakefield?
- Wakefield has 141 open state-funded schools and colleges on the DfE register, with 53,330 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.
