Specialist solar panels for schools in Newton Aycliffe
County Durham has 262 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.
819 kWh per kWp a year at this latitude, so a 250 kWp array, the size applied for at the nearest school scheme on record, models at about 204,800 kWh. 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 County Durham
A one kilowatt-peak array on a shallow pitched roof in Newton Aycliffe models at 819 kWh a year, from modelled irradiation of 1,045 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). 8 percent below our mean puts Newton Aycliffe at the weaker end of the range, which raises the premium on self consumption and lowers the value of anything that leaves the site.
Scaled up, a 250 kWp array, sized to what the nearest school scheme on record applied for, 5 miles away at Bishop Auckland, models at about 204,800 kWh a year before shading, and needs roughly 743 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 53,900 kWh landing in July and August and roughly 8,600 kWh across December and January. Northern Powergrid 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.
Newton Aycliffe ranks 4 of 6 towns we cover in County Durham on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 811 to 845, a spread of 34 kWh per kWp. Within County Durham 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 DL5
The DL5 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 Newton Aycliffe.
Look 5 miles out and there is one: Bishop Auckland College, Woodhouse Lane in Bishop Auckland, 250 kWp, applied for by Bishop Auckland 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 Newton Aycliffe generation curve
A Newton Aycliffe school roof generates most in the weeks its buildings are closed. 26.3 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 14.3 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 4.2 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 7.8 times as much in May as it does in December, and August alone outproduces December by about 6.6 to one. 75 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.
Across the country the arithmetic settles at roughly 49 percent of output on a session day, against about 71 percent for a weekday business. That figure hardly varies by location, which is why the local numbers that matter here are the yield, the roofs and what has already cleared planning nearby.
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.
That argues for a particular shape of scheme rather than against one. Size to the load that does not stop at the end of term, count in lettings, holiday clubs and summer works honestly rather than optimistically, and then decide whether storage or an export arrangement with Northern Powergrid pays for the surplus that is left.
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 Northern Powergrid
Connections around Newton Aycliffe are handled by Northern Powergrid, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a school uses most of what the roof makes during the working day.
Across County Durham the planning database records 85 solar schemes totalling 1168 MW, of which 9 are operational (REPD Q1 2026).
County Durham schools, phase by phase
County Durham has 262 open state-funded schools and colleges on the DfE register teaching 69,907 pupils between them. Source: DfE Get Information About Schools.
The split is 218 primary, 30 secondary, 9 special and 5 further education, at an average of 267 pupils a site. At 7.3 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 County Durham, 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.
Book a roof survey at your Newton Aycliffe school
The first survey answers three questions at once: what the roofs carry, what they generate against your own timetable, and how a Newton Aycliffe school pays for it. Send the postcode, an approximate roof area per block and half hourly meter data if the school can get it from its supplier.
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.
Newton Aycliffe school solar, answered
- How much would a school roof near Newton Aycliffe generate?
- Modelled at 819 kWh per kWp a year, a 250 kWp array on a Newton Aycliffe school models at about 204,800 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 Newton Aycliffe?
- It goes somewhere, just not into the timetable. 26.3 percent of the Newton Aycliffe 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 Northern Powergrid, or a sign the array is too big. We test which before sizing anything.
- Which network operator handles the connection at a Newton Aycliffe school?
- Applications go to Northern Powergrid, who run the network across County Durham. 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 Darlington 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 Darlington on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Darlington before a design is finalised.
- How many schools are there around Newton Aycliffe?
- County Durham has 262 open state-funded schools and colleges on the DfE register, with 69,907 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.
