Specialist solar panels for schools in Peterlee
A 460 kWp array at East Durham College, Willerby Grove is the nearest school scheme on the planning record, and it holds consent and is awaiting construction. We arrange the roof survey, model the output against the school's own half hourly consumption, and set out the funding routes.
388,700 kWh a year, modelled for a 460 kWp array on roughly 1,366 sqm of clear roof. That is the median size schools around Peterlee have applied for. 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.
Which schools around SR8 have applied
The Renewable Energy Planning Database records 1 school and college solar scheme in the SR8 postcode district. A college, East Durham College, Willerby Grove, applied for 460 kWp roof mounted and the scheme holds consent and is awaiting construction. The applicant on record is East Durham & Houghall Community College.
None of these are ours. They are entries in the public planning record, reproduced here because a consented array at a school down the road is a better guide to your own prospects than any national average. Source: Renewable Energy Planning Database, Q1 2026.
One thing to be clear about: the drawing at the head of this page is an illustrative estate, not East Durham College, Willerby Grove and not a survey of anyone's roof. What we know about the scheme above is only what the public planning record says.
The median array applied for here is 460 kWp. At 460 kWp you are covering roughly 1,366 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.

Solar for education buildings across County Durham
A one kilowatt-peak array on a shallow pitched roof in Peterlee models at 845 kWh a year, from modelled irradiation of 1,075 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 5 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 460 kWp array, sized to the median array applied for at schools around Peterlee itself, models at about 388,700 kWh a year before shading, and needs roughly 1,366 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 100,700 kWh landing in July and August and roughly 15,900 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.
Peterlee ranks 1 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.
Term dates against the Peterlee generation curve
A Peterlee school roof generates most in the weeks its buildings are closed. 25.9 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 14.5 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 4.1 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 7.6 times as much in May as it does in December, and August alone outproduces December by about 6.3 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 Peterlee changes that ratio much, but plenty about your own site changes what to do with it.
The same mismatch repeats every day. Peak generation lands between eleven and three, the timetable ends shortly after, and by four the site is down to caretaking and cleaning. An annual consumption figure cannot show that, which is why we ask for the half hourly data instead.
A Peterlee 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

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. Read 7.3 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.
Grid connection through Northern Powergrid
Northern Powergrid 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 County Durham the planning database records 85 solar schemes totalling 1168 MW, of which 9 are operational (REPD Q1 2026).
Book a roof survey at your Peterlee school
Lenzie Consulting Ltd arranges roof surveys for schools across County Durham. 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.
Peterlee school solar, answered
- Is there enough sun around Peterlee for this to be worth doing?
- The model gives 845 kWh a year for every kWp installed at this latitude, so a 460 kWp array comes out at roughly 388,700 kWh a year before shading. It needs about 1,366 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 Peterlee school waste its generation in August?
- 25.9 percent of the modelled annual output for Peterlee 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 Northern Powergrid. We model all three against your half hourly data before an array is sized.
- Will the network around Peterlee accept the export?
- Northern Powergrid is the distribution network operator for County Durham. 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 Peterlee?
- Usually permitted development covers a roof array on a school, with prior approval from County Durham 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.
- Has a school near SR8 already done this?
- One school scheme is on record in this postcode district, including a 460 kWp array at East Durham College, Willerby Grove 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. Source: Renewable Energy Planning Database, Q1 2026.
- How many schools are there around Peterlee?
- 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.
