Specialist solar panels for schools in Rotherham

School rooftop solar across South Yorkshire

A one kilowatt-peak array on a shallow pitched roof in Rotherham models at 835 kWh a year, from modelled irradiation of 1,068 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 6 percent below the mean across the towns we cover, so the case at this latitude rests almost entirely on using the output on site rather than exporting it.

Scaled up, a 320 kWp array, sized to what the nearest school scheme on record applied for, 21 miles away at Mansfield, models at about 267,200 kWh a year before shading, and needs roughly 950 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 69,700 kWh landing in July and August and roughly 12,300 kWh across December and January. Northern Powergrid 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.

What the planning record shows around Rotherham

Search the Renewable Energy Planning Database for the S65 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 21 miles from Rotherham, at Mansfield: 320 kWp at The Samworth Church Academy, Sherwood Hall Road, applicant eEnergy Group PLC, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what Nottinghamshire planning has already accepted at an education site.

The summer holiday problem for a Rotherham school

26.1 percent of the annual output modelled for Rotherham 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. May is the strongest single month here at 13.9 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 4.6 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 6.4 times as much in May as it does in December, and August alone outproduces December by about 5.6 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.

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 Rotherham as anywhere else.

The weekly pattern repeats the annual one. Saturdays and Sundays generate as well as any other day and consume almost nothing, so before storage or export is even discussed it is worth knowing what the site does at a weekend, which only half hourly data will tell you.

The conclusion is not that a Rotherham 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 Northern Powergrid to earn its keep.

How many schools Rotherham has

Rotherham has 124 open state-funded schools and colleges on the DfE register teaching 44,698 pupils between them. Source: DfE Get Information About Schools.

The split is 99 primary, 16 secondary, 7 special and 2 further education, at an average of 360 pupils a site. 6.2 primaries per secondary is a mix weighted towards small sites. The roof area, and therefore most of the generation, sits with the 16 secondaries and the 2 further education sites.

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 Northern Powergrid

Connections around Rotherham are handled by Northern Powergrid, 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 South Yorkshire the planning database records 93 solar schemes totalling 1624 MW, of which 8 are operational (REPD Q1 2026).

Questions governors ask us about Rotherham schools

What would a 320 kWp array produce at a Rotherham school?

Yes, and the figure matters more than the sunshine. 835 kWh per kWp a year puts a 320 kWp array at around 267,200 kWh, on roughly 950 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 Rotherham?

Less is wasted than governors expect, but the figure is worth seeing: 26.1 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 Northern Powergrid.

Who do we apply to for export near Rotherham?

Only Northern Powergrid 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 Rotherham?

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 Rotherham. We confirm it either way.

How many schools are there around Rotherham?

Rotherham has 124 open state-funded schools and colleges on the DfE register, with 44,698 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.
