How much would a school roof near Newquay generate?

Modelled at 940 kWh per kWp a year, a 240 kWp array on a Newquay school models at about 225,600 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 Newquay?

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

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

How many schools are there around Newquay?

Cornwall has 277 open state-funded schools and colleges on the DfE register, with 71,014 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 Newquay

A kilowatt-peak on a Newquay school roof models at 940 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.

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 Cornwall

A one kilowatt-peak array on a shallow pitched roof in Newquay models at 940 kWh a year, from modelled irradiation of 1,194 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 6 percent above the mean across the towns we cover, which is about as strong as a UK school roof gets.

Scaled up, a 240 kWp array, sized to what the nearest school scheme on record applied for, 10 miles away at Truro, models at about 225,600 kWh a year before shading, and needs roughly 713 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 56,600 kWh landing in July and August and roughly 11,500 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.

Newquay ranks 3 of 8 towns we cover in Cornwall on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 921 to 979, a spread of 58 kWh per kWp. On a 500 kWp array that is about 29,000 kWh a year between the strongest and weakest town in the county.

The planning position for Newquay schools

The TR7 postcode district has no education solar entry in the Renewable Energy Planning Database. Almost no school array is large enough to be captured there reliably, so the absence tells you about the reporting threshold and very little about what is already on the roofs around Newquay.

The closest recorded one is about 10 miles away at Truro: Sir Ben Ainslie Sports Centre, Trennick Lane, a 240 kWp roof mounted array applied for by Truro School, which holds consent and is awaiting construction. We were not involved in it. We cite it because it is a public record of what has cleared planning in this part of Cornwall. Source: Renewable Energy Planning Database, Q1 2026.

Why demand in Newquay falls as the roof peaks

The generating year and the school year are out of step in Newquay. July and August carry 25.1 percent of the modelled output (EU PVGIS v5.2), and the site is closed for most of those nine weeks. June is the strongest single month here at 13.6 percent of the annual total, which is still term time, and that works slightly in your favour against towns whose curve peaks in July.

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 Newquay school is fully occupied and its heating and lighting are at their heaviest. The roof makes 5.8 times as much in June 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.

Nationally this comes out at about 49 percent of annual generation falling on a session day. A business open every weekday sees roughly 71 percent. The 22 point gap is what a school appraisal has to absorb, and it is much the same in Newquay as anywhere else.

Then there is the afternoon. From roughly three o'clock the building empties while the roof is still working, so a system sized on annual consumption will over-generate in exactly the hours nobody is there. We size on half hourly data for that reason.

The conclusion is not that a Newquay school should do nothing. It is that the array should be sized to the load that survives the holidays, which is usually the server room, the catering refrigeration, the ventilation and the hot water, plus whatever the site lets out over the summer. Anything above that line needs storage or an export agreement with National Grid Electricity Distribution to earn its keep.

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 Newquay 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.

The school estate in Cornwall

Cornwall has 277 open state-funded schools and colleges on the DfE register teaching 71,014 pupils between them. Source: DfE Get Information About Schools.

The split is 238 primary, 31 secondary, 5 special and 3 further education, at an average of 256 pupils a site. At 7.7 primaries to every secondary, most of the buildings here are small. That is not a reason to skip them, but it does mean the usable area on a primary is a hall roof and a teaching block rather than an estate.

For a trust with more than one site in Cornwall, the first survey is worth running across the whole estate. It tells you which roofs are near the end of their covering life, which have the switchboard headroom, and therefore which one should carry the first array.

Grid connection through National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across Cornwall, 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 Cornwall the planning database records 174 solar schemes totalling 1116 MW, of which 88 are operational (REPD Q1 2026).
