Specialist solar panels for schools in Stamford
What decides a solar scheme at a Stamford 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.
896 kWh per kWp a year at this latitude, so a 170 kWp array, the size applied for at the nearest school scheme on record, models at about 152,300 kWh. 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 Lincolnshire
A one kilowatt-peak array on a shallow pitched roof in Stamford models at 896 kWh a year, from modelled irradiation of 1,145 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). Against a mean of 886 kWh per kWp across the towns we cover, Stamford is unremarkable, which is the useful finding: the scheme will be decided by the load curve, not the map.
Scaled up, a 170 kWp array, sized to what the nearest school scheme on record applied for, 22 miles away at Market Harborough, models at about 152,300 kWh a year before shading, and needs roughly 505 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 39,000 kWh landing in July and August and roughly 7,600 kWh across December and January. National Grid Electricity Distribution 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.
Stamford ranks 4 of 8 towns we cover in Lincolnshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 861 to 906, a spread of 45 kWh per kWp. On a 500 kWp array that is about 22,500 kWh a year between the strongest and weakest town in the county.
School solar on record near PE9
The PE9 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 Stamford.
Look 22 miles out and there is one: The Robert Smyth School, Burnmill Road in Market Harborough, 170 kWp, applied for by Robert Smyth Academy, which was revised and resubmitted. 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 Stamford generation curve
A Stamford 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. July is the single strongest month here at 13.7 percent of the annual total, and it falls almost entirely inside the holiday.
Winter reverses it. December and January between them return 5 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 5.9 times as much in July as it does in December, and August alone outproduces December by about 5 to one. 73 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 Stamford as anywhere else.
Then there is the afternoon. From roughly three o'clock the building empties while the roof is still working, so a system sized on annual consumption will over-generate in exactly the hours nobody is there. We size on half hourly data for that reason.
The conclusion is not that a Stamford 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 National Grid Electricity Distribution to earn its keep.
We set out the complete version of the term time arithmetic on the home page, and what it does to a payback figure under costs.

South Kesteven schools, phase by phase
South Kesteven has 67 open state-funded schools and colleges on the DfE register teaching 21,377 pupils between them. Source: DfE Get Information About Schools.
The split is 53 primary, 10 secondary, 3 special and 1 further education, at an average of 319 pupils a site. At 5.3 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 South Kesteven, 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 National Grid Electricity Distribution
Connections around Stamford are handled by National Grid Electricity Distribution, 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 Lincolnshire the planning database records 226 solar schemes totalling 7052 MW, of which 37 are operational (REPD Q1 2026).
Book a roof survey at your Stamford school
Roof condition decides the order of works on most school estates, so that is where we start. Send us the postcode and a rough roof area, with twelve months of half hourly readings if you have them, and we come back with usable area, modelled output against your own load, and the funding routes.
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.
Stamford school solar, answered
- Is there enough sun around Stamford for this to be worth doing?
- The model gives 896 kWh a year for every kWp installed at this latitude, so a 170 kWp array comes out at roughly 152,300 kWh a year before shading. It needs about 505 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 Stamford school waste its generation in August?
- 25.6 percent of the modelled annual output for Stamford 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 National Grid Electricity Distribution. We model all three against your half hourly data before an array is sized.
- Will the network around Stamford accept the export?
- National Grid Electricity Distribution is the distribution network operator for Lincolnshire. 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 Stamford?
- Usually permitted development covers a roof array on a school, with prior approval from Rutland 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 Stamford?
- South Kesteven has 67 open state-funded schools and colleges on the DfE register, with 21,377 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.
