Specialist solar panels for schools in Folkestone
A school roof in Folkestone makes 6.5 times as much in June 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.
26.1% of the modelled year lands in July and August, on a roof that returns 990 kWh per kWp a year. The worked example below runs at 260 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 Kent
A one kilowatt-peak array on a shallow pitched roof in Folkestone models at 990 kWh a year, from modelled irradiation of 1,248 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 12 percent above the mean across the towns we cover, which is about as strong as a UK school roof gets.
Scaled up, a 260 kWp array, sized to what the nearest school scheme on record applied for, 8 miles away at Dover, models at about 257,400 kWh a year before shading, and needs roughly 772 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 67,200 kWh landing in July and August and roughly 12,100 kWh across December and January. UK Power Networks 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.
Folkestone ranks 2 of 12 towns we cover in Kent on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 915 to 990, a spread of 75 kWh per kWp. On a 500 kWp array that is about 37,500 kWh a year between the strongest and weakest town in the county.
What the planning record shows around Folkestone
The CT20 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 Folkestone.
The nearest education scheme on the record is 8 miles from Folkestone, at Dover: 260 kWp at Westmount Education Centre, applicant Blackap Limited, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Kent planning has already accepted at an education site. Source: Renewable Energy Planning Database, Q1 2026.
The summer holiday problem for a Folkestone school
26.1 percent of the annual output modelled for Folkestone 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. June is the strongest single month here at 14.3 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 4.7 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 6.5 times as much in June as it does in December, and August alone outproduces December by about 5.3 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.
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 Folkestone 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 Folkestone 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 UK Power Networks to earn its keep.

How many schools Folkestone and Hythe has
Folkestone and Hythe has 43 open state-funded schools and colleges on the DfE register teaching 14,936 pupils between them. Source: DfE Get Information About Schools.
The split is 36 primary, 6 secondary and 1 special, at an average of 347 pupils a site. At 6 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 Folkestone and Hythe, 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 UK Power Networks
UK Power Networks operates the distribution network across Kent, 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 Kent the planning database records 237 solar schemes totalling 2072 MW, of which 45 are operational (REPD Q1 2026).
Start with the Folkestone roof
Lenzie Consulting Ltd arranges roof surveys for schools across Kent. 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.
Questions governors ask us about Folkestone schools
- How much would a school roof near Folkestone generate?
- Modelled at 990 kWh per kWp a year, a 260 kWp array on a Folkestone school models at about 257,400 kWh. What decides whether that is worth doing is how much of it the school uses itself, not the total. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- How does the school year affect a solar scheme in Folkestone?
- It goes somewhere, just not into the timetable. 26.1 percent of the Folkestone generating year lands in July and August (EU PVGIS v5.2), and a closed school still runs servers, comms, refrigeration and ventilation. What that base load does not absorb is either stored, exported under an agreement with UK Power Networks, or a sign the array is too big. We test which before sizing anything.
- Which network operator handles the connection at a Folkestone school?
- Applications go to UK Power Networks, who run the network across Kent. An export-limited offer usually still works for a school, because the summer surplus is the part you were least likely to be paid much for anyway.
- What does Folkestone and Hythe require for solar on a school building?
- Roof-mounted solar on a non-domestic building often falls within permitted development under Part 14 of the General Permitted Development Order, subject to limits on how far the panels stand proud of the roof plane and, above a threshold, to prior approval from Folkestone and Hythe on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Folkestone and Hythe before a design is finalised.
- How many schools are there around Folkestone?
- Folkestone and Hythe has 43 open state-funded schools and colleges on the DfE register, with 14,936 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.
