Specialist solar panels for schools in Northallerton

School rooftop solar across North Yorkshire

A one kilowatt-peak array on a shallow pitched roof in Northallerton models at 817 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). That is about 8 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 440 kWp array, sized to what the nearest school scheme on record applied for, 15 miles away at Ripon, models at about 359,500 kWh a year before shading, and needs roughly 1,307 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 94,900 kWh landing in July and August and roughly 15,100 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.

What the planning record shows around Northallerton

The DL6 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 Northallerton.

The nearest education scheme on the record is 15 miles from Northallerton, at Ripon: 440 kWp at Ripon Grammar School, Clotherholme Road, applicant Solar Options for Schools Limited, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what North Yorkshire planning has already accepted at an education site.

The summer holiday problem for a Northallerton school

26.4 percent of the annual output modelled for Northallerton 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 14.4 percent of the annual total, which is still term time, and that works slightly in your favour against towns whose curve peaks in July.

The inverse holds at the other end. December and January together return only 4.2 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 7.9 times as much in May as it does in December, and August alone outproduces December by about 6.6 to one. 76 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.

Nationally this comes out at about 49 percent of annual generation falling on a session day. A business open every weekday sees roughly 71 percent. The 22 point gap is what a school appraisal has to absorb, and it is much the same in Northallerton as anywhere else.

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.

The conclusion is not that a Northallerton school should do nothing. It is that the array should be sized to the load that survives the holidays, which is usually the server room, the catering refrigeration, the ventilation and the hot water, plus whatever the site lets out over the summer. Anything above that line needs storage or an export agreement with Northern Powergrid to earn its keep.

How many schools North Yorkshire has

North Yorkshire has 346 open state-funded schools and colleges on the DfE register teaching 79,545 pupils between them. Source: DfE Get Information About Schools.

The split is 293 primary, 41 secondary, 10 special and 2 further education, at an average of 230 pupils a site. At 7.1 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 North Yorkshire, 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.

Grid connection through Northern Powergrid

Northern Powergrid operates the distribution network across North Yorkshire, so the export application goes to them. Anything larger than 3.68 kW per phase falls under G99, which means an application before commissioning rather than a notification afterwards. A constrained network is not the end of a scheme. Capping export costs little when the building already absorbs most of what the roof produces.

Across North Yorkshire the planning database records 151 solar schemes totalling 1723 MW, of which 18 are operational (REPD Q1 2026).

Questions governors ask us about Northallerton schools

Is there enough sun around Northallerton for this to be worth doing?

The model gives 817 kWh a year for every kWp installed at this latitude, so a 440 kWp array comes out at roughly 359,500 kWh a year before shading. It needs about 1,307 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 Northallerton school waste its generation in August?

26.4 percent of the modelled annual output for Northallerton 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 Northallerton accept the export?

Northern Powergrid is the distribution network operator for North Yorkshire. 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 Northallerton?

Usually permitted development covers a roof array on a school, with prior approval from Hambleton 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 Northallerton?

North Yorkshire has 346 open state-funded schools and colleges on the DfE register, with 79,545 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.
