Specialist solar panels for schools in Flitwick

Solar PV for academy trusts across Bedfordshire

A one kilowatt-peak array on a shallow pitched roof in Flitwick models at 899 kWh a year, from modelled irradiation of 1,151 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is within a few percent of our mean. Latitude is not the variable here. When the building is occupied is.

Scaled up, a 210 kWp array, sized to what the nearest school scheme on record applied for, 9 miles away at Bedford, models at about 188,800 kWh a year before shading, and needs roughly 624 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 48,500 kWh landing in July and August and roughly 9,600 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.

The planning position for Flitwick schools

No school or college solar scheme appears in the MK45 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 Flitwick secondary could be generating today without ever reaching it.

The closest recorded one is about 9 miles away at Bedford: Bedford School, De Parys Avenue, a 210 kWp roof mounted array applied for by Bedford School, which is with the planning authority. We were not involved in it. We cite it because it is a public record of what has cleared planning in this part of Bedfordshire. Source: Renewable Energy Planning Database, Q1 2026.

Why demand in Flitwick falls as the roof peaks

The generating year and the school year are out of step in Flitwick. July and August carry 25.7 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 5.1 percent of output falls in December and January, the two months when a Flitwick school is fully occupied and its heating and lighting are at their heaviest. The roof makes 6 times as much in July as it does in December, and August alone outproduces December by about 5 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.

Put the two calendars together and roughly 49 percent of a school's generation nationally lands on a session day, against about 71 percent for a business open every weekday. That gap is the whole difference between appraising a school roof and appraising any other commercial one, and it barely moves from town to town.

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.

None of that makes a Flitwick scheme a bad one. It changes what the scheme should be: sized against the base load that runs whether or not the school is open, which on most sites is servers, comms, catering refrigeration, ventilation and hot water, with lettings, holiday clubs and summer works added on top. Where that base load is thin, the choices are storage, an export arrangement through UK Power Networks, or a smaller array that consumes nearly everything it makes.

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.

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 Bedfordshire the planning database records 89 solar schemes totalling 837 MW, of which 16 are operational (REPD Q1 2026).

The school estate in Central Bedfordshire

Central Bedfordshire has 128 open state-funded schools and colleges on the DfE register teaching 48,810 pupils between them. Source: DfE Get Information About Schools.

The split is 97 primary, 27 secondary and 4 special, at an average of 381 pupils a site. Read 3.6 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.

What Flitwick trusts ask before a survey

How much would a school roof near Flitwick generate?

Modelled at 899 kWh per kWp a year, a 210 kWp array on a Flitwick school models at about 188,800 kWh. What decides whether that is worth doing is how much of it the school uses itself, not the total. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

How does the school year affect a solar scheme in Flitwick?

It goes somewhere, just not into the timetable. 25.7 percent of the Flitwick generating year lands in July and August (EU PVGIS v5.2), and a closed school still runs servers, comms, refrigeration and ventilation. What that base load does not absorb is either stored, exported under an agreement with UK Power Networks, or a sign the array is too big. We test which before sizing anything.

Which network operator handles the connection at a Flitwick school?

Applications go to UK Power Networks, who run the network across Bedfordshire. An export-limited offer usually still works for a school, because the summer surplus is the part you were least likely to be paid much for anyway.

What does Central Bedfordshire require for solar on a school building?

Roof-mounted solar on a non-domestic building often falls within permitted development under Part 14 of the General Permitted Development Order, subject to limits on how far the panels stand proud of the roof plane and, above a threshold, to prior approval from Central Bedfordshire on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Central Bedfordshire before a design is finalised.

How many schools are there around Flitwick?

Central Bedfordshire has 128 open state-funded schools and colleges on the DfE register, with 48,810 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.
