Specialist solar panels for schools in Ashton-under-Lyne
Tameside College, Beaufort Road sits on the planning record near Ashton-under-Lyne at 400 kWp, which makes the question here less whether a school roof works and more what yours would carry. We look at the roof, the switchboard and the timetable in that order, then set the array size against what the site draws in term time.
307,600 kWh a year, modelled for a 400 kWp array on roughly 1,188 sqm of clear roof. That is the median size schools around Ashton-under-Lyne have applied for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

- first phase
- later phase
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.
Schools near Ashton-under-Lyne already on the planning record
The Renewable Energy Planning Database records 1 school and college solar scheme in the OL6 postcode district. At Tameside College, Beaufort Road, a college, a 400 kWp roof mounted array holds consent and is awaiting construction. The applicant on record is Tameside College.
We had nothing to do with any of them. They are public planning records, and they are on this page because the useful question for a governing body is not whether school solar works in the abstract but whether it has been consented nearby. Source: Renewable Energy Planning Database, Q1 2026.
The site plan at the top of this page is a generic estate drawn to show scale and sequencing. It is not Tameside College, Beaufort Road, and it is not any other building in Ashton-under-Lyne. We hold no drawings, roof data or consumption data for the schools named above.
The median array applied for here is 400 kWp. At 400 kWp you are covering roughly 1,188 square metres of roof once walkways, edge zones and rooflight setbacks come out, which on most sites means a sports hall plus one teaching block rather than the whole estate.
Every one of them is a college, which is worth knowing: a college runs longer days and more plant than a school, and it usually has the flat roof area to match.

School rooftop solar across Greater Manchester
A one kilowatt-peak array on a shallow pitched roof in Ashton-under-Lyne models at 769 kWh a year, from modelled irradiation of 983 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). 13 percent below our mean puts Ashton-under-Lyne 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 400 kWp array, sized to the median array applied for at schools around Ashton-under-Lyne itself, models at about 307,600 kWh a year before shading, and needs roughly 1,188 square metres of clear roof. That size is not one we chose. It is what schools in this district have actually applied for.
Spread across the year that is about 79,400 kWh landing in July and August and roughly 12,000 kWh across December and January. Electricity North West 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.
Ashton-under-Lyne ranks 10 of 10 towns we cover in Greater Manchester on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 769 to 828, a spread of 59 kWh per kWp. On a 500 kWp array that is about 29,500 kWh a year between the strongest and weakest town in the county.
The summer holiday problem for a Ashton-under-Lyne school
25.8 percent of the annual output modelled for Ashton-under-Lyne 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. 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.
The inverse holds at the other end. December and January together return only 3.9 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 7.3 times as much in May as it does in January, and August alone outproduces December by about 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.
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 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.
None of that makes a Ashton-under-Lyne 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 Electricity North West, 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.
- generated while the school is open
- generated at a weekend or in the holidays

Grid connection through Electricity North West
Connections around Ashton-under-Lyne are handled by Electricity North West, 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 Greater Manchester the planning database records 118 solar schemes totalling 110 MW, of which 11 are operational (REPD Q1 2026).
How many schools Tameside has
Tameside has 98 open state-funded schools and colleges on the DfE register teaching 35,801 pupils between them. Source: DfE Get Information About Schools.
The split is 75 primary, 16 secondary, 5 special and 2 further education, at an average of 365 pupils a site. Read 4.7 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.

Lenzie Consulting Ltd arranges roof surveys for schools across Greater Manchester. Send the school postcode and a rough idea of the roof area, and the last twelve months of half hourly meter data if the school holds it. We come back with what the roofs can carry, what they would generate against your own consumption, and the funding routes open to a school.
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.
Questions governors ask us about Ashton-under-Lyne schools
- How much would a school roof near Ashton-under-Lyne generate?
- Modelled at 769 kWh per kWp a year, a 400 kWp array on a Ashton-under-Lyne school models at about 307,600 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 Ashton-under-Lyne?
- It goes somewhere, just not into the timetable. 25.8 percent of the Ashton-under-Lyne 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 Electricity North West, or a sign the array is too big. We test which before sizing anything.
- Which network operator handles the connection at a Ashton-under-Lyne school?
- Applications go to Electricity North West, who run the network across Greater Manchester. 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 Oldham 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 Oldham on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Oldham before a design is finalised.
- Has a school near OL6 already done this?
- One school scheme is on record in this postcode district, including a 400 kWp array at Tameside College, Beaufort Road that holds consent and is awaiting construction. We were not involved in it. It is a public planning record, and it matters less as proof that solar works than as evidence of what this authority and this network operator have already accepted.

- How many schools are there around Ashton-under-Lyne?
- Tameside has 98 open state-funded schools and colleges on the DfE register, with 35,801 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.
