Specialist solar panels for schools in Pontypool
What decides a solar scheme at a Pontypool school is how much of the output the site uses itself, not how much the roof makes. We arrange the roof survey, model the output against the school's own half hourly consumption, and set out the funding routes.
25.6% of the modelled year lands in July and August, on a roof that returns 887 kWh per kWp a year. The worked example below runs at 320 kWp, the size applied for at the nearest school scheme on record. 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 for education buildings across Newport
A one kilowatt-peak array on a shallow pitched roof in Pontypool models at 887 kWh a year, from modelled irradiation of 1,137 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 320 kWp array, sized to what the nearest school scheme on record applied for, 24 miles away at Weston-super-Mare, models at about 283,800 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 72,700 kWh landing in July and August and roughly 14,200 kWh across December and January. The July figure is the one worth putting in front of a governing body first.
Pontypool ranks 4 of 4 towns we cover in Newport on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 887 to 910, a spread of 23 kWh per kWp. Within Newport that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
School solar on record near NP4
The Renewable Energy Planning Database holds no school scheme for the NP4 postcode district. Read that as a gap in the record, not a gap in the roofs: the database is reliable above one megawatt and thin below it, and a school array is typically a fifth of a megawatt.
Look 24 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 Pontypool generation curve
A Pontypool school roof generates most in the weeks its buildings are closed. 25.6 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. June is the strongest single month here at 14 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 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 6.2 times as much in June as it does in December, and August alone outproduces December by about 5.2 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.
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 Pontypool changes that ratio much, but plenty about your own site changes what to do with it.
Daily shape compounds it. A school's load climbs from breakfast club, holds through the teaching day and falls away from about three in the afternoon, while generation is still strong until six in high summer. That is why we size against half hourly meter data rather than against annual consumption: the annual figure hides both problems.
A Pontypool 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.
We set out the full treatment of the school year against the generation curve on the home page, and what it does to a payback figure under costs.
- generated while the school is open
- generated at a weekend or in the holidays

Book a roof survey at your Pontypool school
A survey in Pontypool 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 Pontypool 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.
Pontypool school solar, answered
- What would a 320 kWp array produce at a Pontypool school?
- Yes, and the figure matters more than the sunshine. 887 kWh per kWp a year puts a 320 kWp array at around 283,800 kWh, on roughly 950 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 Pontypool?
- 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 your network operator.
- Do we need planning permission in Torfaen?
- 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 Torfaen. We confirm it either way.
