Specialist solar panels for schools in Bradford
A school roof in Bradford makes 6.8 times as much in May 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 817 kWh per kWp a year. The worked example below runs at 410 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 Bradford models at 817 kWh a year, from modelled irradiation of 1,041 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 8 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 410 kWp array, sized to what the nearest school scheme on record applied for, 25 miles away at Accrington, models at about 335,000 kWh a year before shading, and needs roughly 1,218 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 87,800 kWh landing in July and August and roughly 14,700 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.
Bradford ranks 5 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 Bradford
The Renewable Energy Planning Database holds no school scheme for the BD7 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 25 miles from Bradford, at Accrington: 410 kWp at St Christophers School, Queens Road, applicant Solar Options for Schools Limited, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Lancashire planning has already accepted at an education site. Source: Renewable Energy Planning Database, Q1 2026.
The summer holiday problem for a Bradford school
26.2 percent of the annual output modelled for Bradford 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. May is the strongest single month here at 14.2 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 4.4 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 6.8 times as much in May as it does in December, and August alone outproduces December by about 5.8 to one. 75 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 Bradford changes that ratio much, but plenty about your own site changes what to do with it.
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.
A Bradford 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.

How many schools Bradford has
Bradford has 211 open state-funded schools and colleges on the DfE register teaching 95,219 pupils between them. Source: DfE Get Information About Schools.
The split is 164 primary, 35 secondary, 8 special and 4 further education, at an average of 451 pupils a site. That is 4.7 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
Northern Powergrid 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 West Yorkshire the planning database records 170 solar schemes totalling 550 MW, of which 8 are operational (REPD Q1 2026).
Start with the Bradford roof
Lenzie Consulting Ltd arranges roof surveys for schools across West Yorkshire. 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.
Questions governors ask us about Bradford schools
- What would a 410 kWp array produce at a Bradford school?
- Yes, and the figure matters more than the sunshine. 817 kWh per kWp a year puts a 410 kWp array at around 335,000 kWh, on roughly 1,218 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 Bradford?
- 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 Bradford?
- 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 Bradford?
- 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 Bradford. We confirm it either way.
- How many schools are there around Bradford?
- Bradford has 211 open state-funded schools and colleges on the DfE register, with 95,219 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.
