Specialist solar panels for schools in Whitechapel
A kilowatt-peak on a Whitechapel school roof models at 903 kWh a year, above the mean across the towns we cover, and the roofs it applies to are mostly carrying nothing. The survey records sheet type, remaining life, purlin spacing and the state of the incoming supply, and the model runs off your own meter data rather than an average.
325,100 kWh a year, modelled for a 360 kWp array on roughly 1,069 sqm of clear roof. That is 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 PV for academy trusts across Greater London
A one kilowatt-peak array on a shallow pitched roof in Whitechapel models at 903 kWh a year, from modelled irradiation of 1,163 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is roughly 2 percent above the mean across the towns we cover, so latitude is working slightly in your favour here.
Scaled up, a 360 kWp array, sized to what the nearest school scheme on record applied for, 20 miles away at Sevenoaks, models at about 325,100 kWh a year before shading, and needs roughly 1,069 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 82,900 kWh landing in July and August and roughly 16,900 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.
Whitechapel ranks 33 of 50 towns we cover in Greater London on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 847 to 987, a spread of 140 kWh per kWp. On a 500 kWp array that is about 70,000 kWh a year between the strongest and weakest town in the county.
The planning position for Whitechapel schools
No school or college solar scheme appears in Whitechapel and the area around it in the Renewable Energy Planning Database. That is a reporting threshold rather than a verdict. The database records generating stations from one megawatt upward reliably and smaller ones patchily, and almost every school array is a fraction of that, so a roof full of panels on a Whitechapel secondary could be generating today without ever reaching it.
The closest recorded one is about 20 miles away at Sevenoaks: The Sennocke Centre, High Street, a 360 kWp roof mounted array applied for by Sevenoaks School, which holds consent and is awaiting construction. We were not involved in it. We cite it because it is a public record of what has cleared planning in this part of Kent. Source: Renewable Energy Planning Database, Q1 2026.
Why demand in Whitechapel falls as the roof peaks
The generating year and the school year are out of step in Whitechapel. July and August carry 25.5 percent of the modelled output (EU PVGIS v5.2), and the site is closed for most of those nine weeks. July is the single strongest month here at 13.8 percent of the annual total, and it falls almost entirely inside the holiday.
At the other end of the year the mismatch flips. Only 5.2 percent of output falls in December and January, the two months when a Whitechapel school is fully occupied and its heating and lighting are at their heaviest. The roof makes 5.7 times as much in July as it does in December, and August alone outproduces December by about 4.8 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 Whitechapel as anywhere else.
And the week has the same hole in it. Two days in seven the site is closed altogether, at no cost to the generation, which is part of why the session day share sits where it does. Weekend lettings are the one lever a Whitechapel school has over that, and they are worth counting properly.
The conclusion is not that a Whitechapel 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.
We set out the whole argument about term dates and the generation curve on the home page, and what it does to a payback figure under costs.

- generated at a weekend or in the holidays

The school estate in Tower Hamlets
Tower Hamlets has 93 open state-funded schools and colleges on the DfE register teaching 43,608 pupils between them. Source: DfE Get Information About Schools.
The split is 69 primary, 18 secondary, 4 special and 2 further education, at an average of 469 pupils a site. Read 3.8 primaries per secondary as a sequencing hint rather than a statistic. A primary is a single survey visit and a modest array; a secondary is several roofs of different ages on one site, and that is where both the area and the complications are.
A trust holding more than one of these sites should look at them together. Grouping the surveys turns the grid question, the funding question and the procurement route into one exercise rather than four, and it usually changes which roof goes first.
Grid connection through UK Power Networks
Connections around Whitechapel are handled by UK Power Networks, 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.
Send us the school postcode
A survey in Whitechapel 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 Whitechapel 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.
What Whitechapel trusts ask before a survey
- How much would a school roof near Whitechapel generate?
- Modelled at 903 kWh per kWp a year, a 360 kWp array on a Whitechapel school models at about 325,100 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 Whitechapel?
- It goes somewhere, just not into the timetable. 25.5 percent of the Whitechapel 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 Whitechapel school?
- Applications go to UK Power Networks, who run the network across Greater London. 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.
- How many schools are there around Whitechapel?
- Tower Hamlets has 93 open state-funded schools and colleges on the DfE register, with 43,608 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.
