Specialist solar panels for schools in Rochdale
What decides a solar scheme at a Rochdale 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.

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 Greater Manchester
A one kilowatt-peak array on a shallow pitched roof in Rochdale models at 771 kWh a year, from modelled irradiation of 985 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 13 percent below the mean across the towns we cover, so the case at this latitude rests almost entirely on using the output on site rather than exporting it.
Scaled up, a 400 kWp array, sized to what the nearest school scheme on record applied for, 9 miles away at Ashton-under-Lyne, models at about 308,400 kWh a year before shading, and needs roughly 1,188 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 79,000 kWh landing in July and August and roughly 12,300 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.
Rochdale ranks 8 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.
School solar on record near OL11
Search the Renewable Energy Planning Database for the OL11 postcode district and nothing comes back under education. That is worth stating plainly and then setting aside: the register is built around generating stations, a school array is a fraction of the size it captures reliably, and plenty of school roofs never appear in any national record at all.
Look 9 miles out and there is one: Tameside College, Beaufort Road in Ashton-under-Lyne, 400 kWp, applied for by Tameside 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 Rochdale generation curve
A Rochdale 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. May is the strongest single month here at 14.4 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 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 7.4 times as much in May as it does in December, 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.
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 Rochdale changes that ratio much, but plenty about your own site changes what to do with it.
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.
A Rochdale 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 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

Rochdale schools, phase by phase
Rochdale has 91 open state-funded schools and colleges on the DfE register teaching 37,474 pupils between them. Source: DfE Get Information About Schools.
The split is 71 primary, 13 secondary, 5 special and 2 further education, at an average of 412 pupils a site. 5.5 primaries per secondary is a mix weighted towards small sites. The roof area, and therefore most of the generation, sits with the 13 secondaries and the 2 further education sites.
Across an estate of that size the roofs will not be in the same condition, and that is the point of surveying them together: the block with the best orientation is often not the block whose covering has twenty years left in it.
Grid connection through Electricity North West
Electricity North West is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Greater Manchester the planning database records 118 solar schemes totalling 110 MW, of which 11 are operational (REPD Q1 2026).
Book a roof survey at your Rochdale school
A survey in Rochdale 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 Rochdale 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.
Rochdale school solar, answered
- Is there enough sun around Rochdale for this to be worth doing?
- The model gives 771 kWh a year for every kWp installed at this latitude, so a 400 kWp array comes out at roughly 308,400 kWh a year before shading. It needs about 1,188 square metres of clear roof once walkways and rooflight setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Does a Rochdale school waste its generation in August?
- 25.6 percent of the modelled annual output for Rochdale falls in July and August, when the buildings are closed for most of six weeks (EU PVGIS v5.2). It does not go to waste, but it only has three places to go: the base load that runs regardless, such as servers, catering refrigeration and ventilation; storage; or export under an agreement with Electricity North West. We model all three against your half hourly data before an array is sized.
- Will the network around Rochdale accept the export?
- Electricity North West is the distribution network operator for Greater Manchester. Anything above 3.68 kW per phase connects under G99, and the application fixes the export limit. On a school site the incoming supply is often the binding constraint rather than the roof, so we ask that question before anyone sizes an array.
- Is planning permission needed for panels on a school in Rochdale?
- Usually permitted development covers a roof array on a school, with prior approval from Rochdale needed above a capacity threshold. A ground mounted array in the grounds is a different question and much more likely to need a full application. We check both before design sign-off.
- How many schools are there around Rochdale?
- Rochdale has 91 open state-funded schools and colleges on the DfE register, with 37,474 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.
