Specialist solar panels for schools in Blackburn

School solar consented near Blackburn

The Renewable Energy Planning Database records 1 school and college solar scheme in the BB2 postcode district. Tauheedul Islam Girls High School, Preston New Road is down for a an unstated capacity roof mounted array and the application holds consent and is awaiting construction. The applicant on record is Star Academies.

Those are other organisations' planning applications, not our projects. We list them because a scheme a few miles away tells you what this local authority and this network operator have already accepted for a building very like yours. Source: Renewable Energy Planning Database, Q1 2026.

The plan above the fold is a generic four block estate, drawn to make the scale and the phasing legible. Nobody should read it as Tauheedul Islam Girls High School, Preston New Road or as any other Blackburn site. Our knowledge of these applications comes entirely from the public record.

Every one of them is a secondary school, which is worth knowing: a secondary site normally has a sports hall, a dining block and several flat roofs, which is where the usable area comes from.

Solar PV for academy trusts across Lancashire

A one kilowatt-peak array on a shallow pitched roof in Blackburn models at 782 kWh a year, from modelled irradiation of 997 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 12 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 410 kWp array, sized to what the nearest school scheme on record applied for, 5 miles away at Accrington, models at about 320,600 kWh a year before shading, and needs roughly 1,218 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 83,000 kWh landing in July and August and roughly 12,200 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.

Why demand in Blackburn falls as the roof peaks

The generating year and the school year are out of step in Blackburn. July and August carry 25.9 percent of the modelled output (EU PVGIS v5.2), and the site is closed for most of those nine weeks. 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.

At the other end of the year the mismatch flips. Only 3.8 percent of output falls in December and January, the two months when a Blackburn school is fully occupied and its heating and lighting are at their heaviest. The roof makes 8.1 times as much in May as it does in December, and August alone outproduces December by about 6.6 to one. 76 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 Blackburn 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 Blackburn 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 Electricity North West to earn its keep.

The school estate in Blackburn with Darwen

Blackburn with Darwen has 77 open state-funded schools and colleges on the DfE register teaching 27,880 pupils between them. Source: DfE Get Information About Schools.

The split is 61 primary, 12 secondary, 3 special and 1 further education, at an average of 362 pupils a site. A ratio of 5.1 to one tells you where the roof area is. It is not with the 61 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.

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).

What Blackburn trusts ask before a survey

What would a 410 kWp array produce at a Blackburn school?

Yes, and the figure matters more than the sunshine. 782 kWh per kWp a year puts a 410 kWp array at around 320,600 kWh, on roughly 1,218 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 Blackburn?

Less is wasted than governors expect, but the figure is worth seeing: 25.9 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 Blackburn?

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 Blackburn with Darwen?

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 Blackburn with Darwen. We confirm it either way.

Has a school near BB2 already done this?

One school scheme is on record in this postcode district, including a 0 kWp array at Tauheedul Islam Girls High School, Preston New Road that holds consent and is awaiting construction. We were not involved in it. It is a public planning record, and it matters less as proof that solar works than as evidence of what this authority and this network operator have already accepted.

How many schools are there around Blackburn?

Blackburn with Darwen has 77 open state-funded schools and colleges on the DfE register, with 27,880 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.
