How much would a school roof near Bridgwater generate?

Modelled at 931 kWh per kWp a year, a 320 kWp array on a Bridgwater school models at about 297,900 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 Bridgwater?

It goes somewhere, just not into the timetable. 25.1 percent of the Bridgwater 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 Bridgwater school?

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

How many schools are there around Bridgwater?

Somerset has 266 open state-funded schools and colleges on the DfE register, with 68,648 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.

Specialist solar panels for schools in Bridgwater

Somerset has 266 state-funded schools and colleges, and most of them are buying electricity in exactly the hours their own roofs could be making it. We start with the roof build up and the age of the covering, because across a school estate that is usually what decides which block goes first.

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 for education buildings across Somerset

A one kilowatt-peak array on a shallow pitched roof in Bridgwater models at 931 kWh a year, from modelled irradiation of 1,187 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). At 5 percent above our mean, Bridgwater is at the strong end of the range, and a roof here earns more for every square metre than the same roof would further north.

Scaled up, a 320 kWp array, sized to what the nearest school scheme on record applied for, 15 miles away at Weston-super-Mare, models at about 297,900 kWh a year before shading, and needs roughly 950 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 74,800 kWh landing in July and August and roughly 15,200 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.

Bridgwater ranks 2 of 8 towns we cover in Somerset on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 894 to 934, a spread of 40 kWh per kWp. Within Somerset that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: latitude is not the lever, the timetable is. Source: EU PVGIS v5.2, modelled per town

School solar on record near TA6

No school or college solar scheme appears in the TA6 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 Bridgwater secondary could be generating today without ever reaching it.

Look 15 miles out and there is one: Weston College in Weston-super-Mare, 300 kWp, applied for by Weston College, which holds consent and is awaiting construction. None of our doing. It is a public planning record, and the nearest evidence available of how an application like yours is treated around here. Source: Renewable Energy Planning Database, Q1 2026.

Term dates against the Bridgwater generation curve

A Bridgwater school roof generates most in the weeks its buildings are closed. 25.1 percent of the modelled year lands in July and August alone (EU PVGIS v5.2), and the summer holiday takes roughly six of those nine weeks out of the timetable. May is the strongest single month here at 13.8 percent of the annual total, which is still term time, and that works slightly in your favour against towns whose curve peaks in July.

Winter reverses it. December and January between them return 5.1 percent of the modelled year, and that is when the heating, the lighting and a full register are all drawing at the same time. The roof makes 6.1 times as much in May 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.

And the week has the same hole in it. Two days in seven the site is closed altogether, at no cost to the generation, which is part of why the session day share sits where it does. Weekend lettings are the one lever a Bridgwater school has over that, and they are worth counting properly.

None of that makes a Bridgwater 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 whole argument about term dates and the generation curve on the home page, and what it does to a payback figure under costs.

Per kWp installed, month by month, separating generation while the school is open from generation at a weekend or in the holidays. 73 percent of the Bridgwater year sits between April and September, most of which is term time; it is the tail of that period, the last week of July and all of August, that the school is not there for. The daily split is a flat apportionment of each month, not a metered one. Session days follow a typical English school year of 190 days. Your own trust or authority may differ by a few days either way. Source: EU PVGIS v5.2, session days from a typical school calendar

Grid connection through National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across Somerset, 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 Somerset the planning database records 223 solar schemes totalling 1574 MW, of which 79 are operational (REPD Q1 2026).

Somerset schools, phase by phase

Somerset has 266 open state-funded schools and colleges on the DfE register teaching 68,648 pupils between them. Source: DfE Get Information About Schools.

The split is 219 primary, 35 secondary, 9 special and 3 further education, at an average of 258 pupils a site. Read 6.3 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.

Book the survey

Book a roof survey at your Bridgwater school

A survey in Bridgwater starts with three things from you. Give us the postcode, the approximate roof area and, if you can get it from your supplier, twelve months of half hourly readings. What comes back is a usable area figure per block, output modelled against your own load rather than an average, and the ways a Bridgwater school can pay for it.

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.
