Specialist solar panels for schools in Bracknell
A kilowatt-peak on a Bracknell school roof models at 891 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.
891 kWh per kWp a year at this latitude, so a 490 kWp array, the size applied for at the nearest school scheme on record, models at about 436,600 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.
Solar PV for academy trusts across Berkshire
A one kilowatt-peak array on a shallow pitched roof in Bracknell models at 891 kWh a year, from modelled irradiation of 1,145 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 490 kWp array, sized to what the nearest school scheme on record applied for, 7 miles away at Windsor, models at about 436,600 kWh a year before shading, and needs roughly 1,455 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 111,800 kWh landing in July and August and roughly 23,100 kWh across December and January. Scottish and Southern Electricity 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.
Bracknell ranks 8 of 8 towns we cover in Berkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 891 to 910, a spread of 19 kWh per kWp. Within Berkshire 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 Bracknell schools
Search the Renewable Energy Planning Database for the RG12 postcode district and nothing comes back under education. That is worth stating plainly and then setting aside: the register is built around generating stations, a school array is a fraction of the size it captures reliably, and plenty of school roofs never appear in any national record at all.
The closest recorded one is about 7 miles away at Windsor: St Johns Beaumont School, Priest Hill, a 260 kWp roof mounted array applied for by St Johns Beaumont School, which was refused. We were not involved in it. We cite it because it is a public record of what has cleared planning in this part of Berkshire. Source: Renewable Energy Planning Database, Q1 2026.
Why demand in Bracknell falls as the roof peaks
The generating year and the school year are out of step in Bracknell. July and August carry 25.6 percent of the modelled output (EU PVGIS v5.2), and the site is closed for most of those nine weeks. July is the single strongest month here at 13.9 percent of the annual total, and it falls almost entirely inside the holiday.
At the other end of the year the mismatch flips. Only 5.3 percent of output falls in December and January, the two months when a Bracknell school is fully occupied and its heating and lighting are at their heaviest. The roof makes 5.6 times as much in July as it does in December, and August alone outproduces December by about 4.7 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 Bracknell 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 Bracknell school is largely empty, so the hours that look best on a generation chart are the worst on a consumption one.
A Bracknell 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 Bracknell Forest
Bracknell Forest has 38 open state-funded schools and colleges on the DfE register teaching 18,944 pupils between them. Source: DfE Get Information About Schools.
The split is 29 primary, 7 secondary and 2 special, at an average of 499 pupils a site. 4.1 primaries per secondary is a mix weighted towards small sites. The roof area, and therefore most of the generation, sits with the 7 secondaries.
Across an estate of that size the roofs will not be in the same condition, and that is the point of surveying them together: the block with the best orientation is often not the block whose covering has twenty years left in it.
Grid connection through Scottish and Southern Electricity Networks
Scottish and Southern Electricity 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 Berkshire the planning database records 83 solar schemes totalling 317 MW, of which 8 are operational (REPD Q1 2026).
Send us the school postcode
The first survey answers three questions at once: what the roofs carry, what they generate against your own timetable, and how a Bracknell 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.
What Bracknell trusts ask before a survey
- What would a 490 kWp array produce at a Bracknell school?
- Yes, and the figure matters more than the sunshine. 891 kWh per kWp a year puts a 490 kWp array at around 436,600 kWh, on roughly 1,455 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 Bracknell?
- 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 Scottish and Southern Electricity Networks.
- Who do we apply to for export near Bracknell?
- Only Scottish and Southern Electricity 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 Bracknell Forest?
- 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 Bracknell Forest. We confirm it either way.
- How many schools are there around Bracknell?
- Bracknell Forest has 38 open state-funded schools and colleges on the DfE register, with 18,944 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.
