Specialist solar panels for schools in Knaresborough
What decides a solar scheme at a Knaresborough 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.
26.3% of the modelled year lands in July and August, on a roof that returns 833 kWh per kWp a year. The worked example below runs at 440 kWp, the size applied for at the nearest school scheme on record. 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 North Yorkshire
A one kilowatt-peak array on a shallow pitched roof in Knaresborough models at 833 kWh a year, from modelled irradiation of 1,065 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 6 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, 10 miles away at Ripon, models at about 366,500 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 96,400 kWh landing in July and August and roughly 15,800 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.
Knaresborough ranks 5 of 8 towns we cover in North Yorkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 799 to 859, a spread of 60 kWh per kWp. On a 500 kWp array that is about 30,000 kWh a year between the strongest and weakest town in the county.
School solar on record near HG5
The HG5 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 Knaresborough.
Look 10 miles out and there is one: Ripon Grammar School, Clotherholme Road in Ripon, 440 kWp, applied for by Solar Options for Schools Limited, 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 Knaresborough generation curve
A Knaresborough 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 14.1 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 4.3 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 6.9 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 Knaresborough changes that ratio much, but plenty about your own site changes what to do with it.
Daily shape compounds it. A school's load climbs from breakfast club, holds through the teaching day and falls away from about three in the afternoon, while generation is still strong until six in high summer. That is why we size against half hourly meter data rather than against annual consumption: the annual figure hides both problems.
A Knaresborough 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.

North Yorkshire schools, phase by phase
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
Connections around Knaresborough 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 North Yorkshire the planning database records 151 solar schemes totalling 1723 MW, of which 18 are operational (REPD Q1 2026).
Book a roof survey at your Knaresborough school
The first survey answers three questions at once: what the roofs carry, what they generate against your own timetable, and how a Knaresborough 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.
Knaresborough school solar, answered
- Is there enough sun around Knaresborough for this to be worth doing?
- The model gives 833 kWh a year for every kWp installed at this latitude, so a 440 kWp array comes out at roughly 366,500 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 Knaresborough school waste its generation in August?
- 26.3 percent of the modelled annual output for Knaresborough 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 Knaresborough 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 Knaresborough?
- Usually permitted development covers a roof array on a school, with prior approval from Harrogate 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 Knaresborough?
- 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.
