Specialist solar panels for schools in Warwick
A school roof in Warwick makes 6.1 times as much in July as it does in December, and the school year runs against that curve rather than with it. What we come back with is the usable roof area, the modelled output against your meter data, and the routes schools use to pay for it.
25.7% of the modelled year lands in July and August, on a roof that returns 880 kWh per kWp a year. The worked example below runs at 460 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.

- first phase
- later phase
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.
School rooftop solar across Warwickshire
A one kilowatt-peak array on a shallow pitched roof in Warwick models at 880 kWh a year, from modelled irradiation of 1,127 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the towns we cover, so what decides the scheme is the school's own demand pattern rather than where in the country it stands.
Scaled up, a 460 kWp array, sized to what the nearest school scheme on record applied for, 10 miles away at Coventry, models at about 404,800 kWh a year before shading, and needs roughly 1,366 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 104,000 kWh landing in July and August and roughly 19,800 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.
Warwick ranks 3 of 7 towns we cover in Warwickshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 866 to 893, a spread of 27 kWh per kWp. Within Warwickshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
What the planning record shows around Warwick
Search the Renewable Energy Planning Database for the CV34 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.
The nearest education scheme on the record is 10 miles from Warwick, at Coventry: 460 kWp at City College, Swanswell Street, applicant EON Control Solutions Limited, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what West Midlands planning has already accepted at an education site.

The summer holiday problem for a Warwick school
25.7 percent of the annual output modelled for Warwick 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. July is the single strongest month here at 13.9 percent of the annual total, and it falls almost entirely inside the holiday.
The inverse holds at the other end. December and January together return only 4.9 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 6.1 times as much in July as it does in December, and August alone outproduces December by about 5.2 to one. 74 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 Warwick changes that ratio much, but plenty about your own site changes what to do with it.
The daily curve does the same thing in miniature. Load drops sharply after about three o'clock, generation does not, so the last three hours of a summer afternoon are pushing into an empty building unless something absorbs them. Half hourly meter data is the only way to see how much.
A Warwick 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.

How many schools Warwick has
Warwick has 55 open state-funded schools and colleges on the DfE register teaching 19,093 pupils between them. Source: DfE Get Information About Schools.
The split is 46 primary, 7 secondary, 1 special and 1 further education, at an average of 347 pupils a site. 6.6 primaries per secondary is a mix weighted towards small sites. The roof area, and therefore most of the generation, sits with the 7 secondaries and the 1 further education site.
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 National Grid Electricity Distribution
National Grid Electricity Distribution 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 Warwickshire the planning database records 94 solar schemes totalling 1201 MW, of which 18 are operational (REPD Q1 2026).
Start with the Warwick roof
A survey in Warwick 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 Warwick 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.
Questions governors ask us about Warwick schools
- What would a 460 kWp array produce at a Warwick school?
- Yes, and the figure matters more than the sunshine. 880 kWh per kWp a year puts a 460 kWp array at around 404,800 kWh, on roughly 1,366 square metres of roof. The value of that depends on your term time load. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- What happens to the electricity during the summer holidays in Warwick?
- Less is wasted than governors expect, but the figure is worth seeing: 25.7 percent of the year is modelled to arrive in July and August here (EU PVGIS v5.2), against a site running on holiday base load. Lettings, holiday clubs and summer works take some of it, storage takes more, and the rest is an export question for National Grid Electricity Distribution.
- Who do we apply to for export near Warwick?
- Only National Grid Electricity Distribution can answer it for your connection. What we can say is that a capped export limit rarely breaks a school scheme, because the array that suits a school is sized to the term time load rather than to the roof.
- Do we need planning permission in Warwick?
- Often not, because panels on the roof of a school building usually sit within permitted development for non-domestic buildings. The exceptions are listed buildings, conservation areas and arrays that project too far above the roof plane, and larger schemes still need prior approval from Warwick. We confirm it either way.
- How many schools are there around Warwick?
- Warwick has 55 open state-funded schools and colleges on the DfE register, with 19,093 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.
