Specialist solar panels for schools in Malvern
National Grid Electricity Distribution runs the network around Malvern, and on a school site their answer on export shapes the design as much as the roof pitch does. We look at the roof, the switchboard and the timetable in that order, then set the array size against what the site draws in term time.
875 kWh per kWp a year at this latitude, so a 160 kWp array, the size applied for at the nearest school scheme on record, models at about 140,000 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.
School rooftop solar across Worcestershire
A one kilowatt-peak array on a shallow pitched roof in Malvern models at 875 kWh a year, from modelled irradiation of 1,122 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is within a few percent of our mean. Latitude is not the variable here. When the building is occupied is.
Scaled up, a 160 kWp array, sized to what the nearest school scheme on record applied for, 19 miles away at Cheltenham, models at about 140,000 kWh a year before shading, and needs roughly 475 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 36,300 kWh landing in July and August and roughly 5,900 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.
Malvern ranks 5 of 7 towns we cover in Worcestershire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 866 to 882, a spread of 16 kWh per kWp. Within Worcestershire 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 Malvern
Search the Renewable Energy Planning Database for Malvern and the area around it 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 19 miles from Malvern, at Cheltenham: 160 kWp at Ladies College Swimming Pool, Malvern Road, applicant Ladies College Swimming Pool, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Gloucestershire planning has already accepted at an education site.

The summer holiday problem for a Malvern school
25.9 percent of the annual output modelled for Malvern 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 14.1 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 4.2 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 7.7 times as much in July as it does in December, and August alone outproduces December by about 6.5 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.
Put the two calendars together and roughly 49 percent of a school's generation nationally lands on a session day, against about 71 percent for a business open every weekday. That gap is the whole difference between appraising a school roof and appraising any other commercial one, and it barely moves from town to town.
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.
None of that makes a Malvern scheme a bad one. It changes what the scheme should be: sized against the base load that runs whether or not the school is open, which on most sites is servers, comms, catering refrigeration, ventilation and hot water, with lettings, holiday clubs and summer works added on top. Where that base load is thin, the choices are storage, an export arrangement through National Grid Electricity Distribution, or a smaller array that consumes nearly everything it makes.
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.

- generated at a weekend or in the holidays

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across Worcestershire, 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 Worcestershire the planning database records 62 solar schemes totalling 506 MW, of which 6 are operational (REPD Q1 2026).
How many schools Malvern Hills has
Malvern Hills has 40 open state-funded schools and colleges on the DfE register teaching 9,784 pupils between them. Source: DfE Get Information About Schools.
The split is 35 primary and 5 secondary, at an average of 245 pupils a site. 7 primaries per secondary is a mix weighted towards small sites. The roof area, and therefore most of the generation, sits with the 5 secondaries.
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.
Start with the Malvern roof
We survey school and college roofs throughout Worcestershire. We need the postcode, a rough roof area and your half hourly meter data if the trust has it. From that we model what the roof carries, what it generates against the timetable, and which of the funding routes actually suits a school of your size.
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 Malvern schools
- How much would a school roof near Malvern generate?
- Modelled at 875 kWh per kWp a year, a 160 kWp array on a Malvern school models at about 140,000 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 Malvern?
- It goes somewhere, just not into the timetable. 25.9 percent of the Malvern 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 National Grid Electricity Distribution, or a sign the array is too big. We test which before sizing anything.
- Which network operator handles the connection at a Malvern school?
- Applications go to National Grid Electricity Distribution, who run the network across Worcestershire. 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 Malvern?
- Malvern Hills has 40 open state-funded schools and colleges on the DfE register, with 9,784 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.
