Specialist solar panels for schools in Bridgnorth

School rooftop solar across Shropshire

A one kilowatt-peak array on a shallow pitched roof in Bridgnorth models at 856 kWh a year, from modelled irradiation of 1,096 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). Bridgnorth sits 3 percent under our mean. Worth knowing, but not decisive: how well the array matches the timetable moves the answer further than the latitude does.

Scaled up, a 150 kWp array, sized to what the nearest school scheme on record applied for, 23 miles away at Stafford, models at about 128,400 kWh a year before shading, and needs roughly 446 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 32,900 kWh landing in July and August and roughly 6,300 kWh across December and January. National Grid Electricity Distribution 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.

What the planning record shows around Bridgnorth

There is no school entry for the WV16 postcode district in the Renewable Energy Planning Database. The register is dependable for anything from a megawatt upward and incomplete below it, and a school array is usually nearer a fifth of a megawatt, so this says more about the threshold than about Bridgnorth.

The nearest education scheme on the record is 23 miles from Bridgnorth, at Stafford: 150 kWp at Stafford Manor High School, Rising Brook, applicant eEnergy Group PLC, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Staffordshire planning has already accepted at an education site.

The summer holiday problem for a Bridgnorth school

25.6 percent of the annual output modelled for Bridgnorth 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. June is the strongest single month here at 13.9 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 4.9 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 times as much in June as it does in December, and August alone outproduces December by about 5 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.

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 daily curve does the same thing in miniature. Load drops sharply after about three o'clock, generation does not, so the last three hours of a summer afternoon are pushing into an empty building unless something absorbs them. Half hourly meter data is the only way to see how much.

None of that makes a Bridgnorth 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 National Grid Electricity Distribution, or a smaller array that consumes nearly everything it makes.

We set out the complete version of the term time arithmetic on the home page, and what it does to a payback figure under costs.

Grid connection through National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across Shropshire, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.

Across Shropshire the planning database records 110 solar schemes totalling 813 MW, of which 27 are operational (REPD Q1 2026).

How many schools Shropshire has

Shropshire has 151 open state-funded schools and colleges on the DfE register teaching 39,029 pupils between them. Source: DfE Get Information About Schools.

The split is 127 primary, 20 secondary, 3 special and 1 further education, at an average of 258 pupils a site. A ratio of 6.4 to one tells you where the roof area is. It is not with the 127 primaries, which mostly offer a hall and a teaching block each, but with the larger sites that were built with a sports hall and a dining block attached.

Where a multi-academy trust holds several of those sites, surveying the estate in one pass beats taking a roof at a time. The design work, the connection applications and the procurement paperwork are the same job repeated, and a trust that runs them together gets a better answer on all three.

Questions governors ask us about Bridgnorth schools

How much would a school roof near Bridgnorth generate?

Modelled at 856 kWh per kWp a year, a 150 kWp array on a Bridgnorth school models at about 128,400 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 Bridgnorth?

It goes somewhere, just not into the timetable. 25.6 percent of the Bridgnorth 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 National Grid Electricity Distribution, or a sign the array is too big. We test which before sizing anything.

Which network operator handles the connection at a Bridgnorth school?

Applications go to National Grid Electricity Distribution, who run the network across Shropshire. 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 Shropshire 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 Shropshire on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Shropshire before a design is finalised.

How many schools are there around Bridgnorth?

Shropshire has 151 open state-funded schools and colleges on the DfE register, with 39,029 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.
