Specialist solar panels for schools in Preston

Solar for education buildings across Lancashire

A one kilowatt-peak array on a shallow pitched roof in Preston models at 805 kWh a year, from modelled irradiation of 1,028 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). 9 percent below our mean puts Preston at the weaker end of the range, which raises the premium on self consumption and lowers the value of anything that leaves the site.

Scaled up, a 290 kWp array, sized to what the nearest school scheme on record applied for, 9 miles away at Chorley, models at about 233,500 kWh a year before shading, and needs roughly 861 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 60,000 kWh landing in July and August and roughly 9,300 kWh across December and January. Electricity North West 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.

School solar on record near PR1

There is no school entry for the PR1 postcode district in the Renewable Energy Planning Database. The register is dependable for anything from a megawatt upward and incomplete below it, and a school array is usually nearer a fifth of a megawatt, so this says more about the threshold than about Preston.

Look 9 miles out and there is one: Parklands High School, Southport Road - Solar Photovoltaic Panels in Chorley, 290 kWp, applied for by Parklands High School, which holds consent and is awaiting construction. None of our doing. It is a public planning record, and the nearest evidence available of how an application like yours is treated around here. Source: Renewable Energy Planning Database, Q1 2026.

Term dates against the Preston generation curve

A Preston school roof generates most in the weeks its buildings are closed. 25.7 percent of the modelled year lands in July and August alone (EU PVGIS v5.2), and the summer holiday takes roughly six of those nine weeks out of the timetable. May is the strongest single month here at 14.5 percent of the annual total, which is still term time, and that works slightly in your favour against towns whose curve peaks in July.

Winter reverses it. December and January between them return 4 percent of the modelled year, and that is when the heating, the lighting and a full register are all drawing at the same time. The roof makes 7.8 times as much in May as it does in December, and August alone outproduces December by about 6.3 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.

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.

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.

None of that makes a Preston 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 Electricity North West, 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.

Grid connection through Electricity North West

Electricity North West 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 Lancashire the planning database records 161 solar schemes totalling 521 MW, of which 25 are operational (REPD Q1 2026).

Preston schools, phase by phase

Preston has 72 open state-funded schools and colleges on the DfE register teaching 21,724 pupils between them. Source: DfE Get Information About Schools.

The split is 55 primary, 10 secondary, 4 special and 3 further education, at an average of 302 pupils a site. A ratio of 5.5 to one tells you where the roof area is. It is not with the 55 primaries, which mostly offer a hall and a teaching block each, but with the larger sites that were built with a sports hall and a dining block attached.

Where a multi-academy trust holds several of those sites, surveying the estate in one pass beats taking a roof at a time. The design work, the connection applications and the procurement paperwork are the same job repeated, and a trust that runs them together gets a better answer on all three.

Preston school solar, answered

What would a 290 kWp array produce at a Preston school?

Yes, and the figure matters more than the sunshine. 805 kWh per kWp a year puts a 290 kWp array at around 233,500 kWh, on roughly 861 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 Preston?

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 Electricity North West.

Who do we apply to for export near Preston?

Only Electricity North West 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 Preston?

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 Preston. We confirm it either way.

How many schools are there around Preston?

Preston has 72 open state-funded schools and colleges on the DfE register, with 21,724 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.
