How much would a school roof near Workington generate?

Modelled at 835 kWh per kWp a year, a 210 kWp array on a Workington school models at about 175,400 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 Workington?

It goes somewhere, just not into the timetable. 26 percent of the Workington 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 Electricity North West, or a sign the array is too big. We test which before sizing anything.

Which network operator handles the connection at a Workington school?

Applications go to Electricity North West, who run the network across Cumbria. 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.

What does Allerdale require for solar on a school building?

Roof-mounted solar on a non-domestic building often falls within permitted development under Part 14 of the General Permitted Development Order, subject to limits on how far the panels stand proud of the roof plane and, above a threshold, to prior approval from Allerdale on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Allerdale before a design is finalised.

How many schools are there around Workington?

Cumberland has 171 open state-funded schools and colleges on the DfE register, with 38,686 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.

Specialist solar panels for schools in Workington

A kilowatt-peak on a Workington school roof models at 835 kWh a year, below 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.

835 kWh per kWp a year at this latitude, so a 210 kWp array, the size applied for at the nearest school scheme on record, models at about 175,400 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.

Workington / Cumbria

A school on the edge of a Greater Manchester town, solar arrays on its roofs and low Pennine hills beyond — School buildings of the kind we survey across North West. Not a named school and not our work.

Solar PV for academy trusts across Cumbria

A one kilowatt-peak array on a shallow pitched roof in Workington models at 835 kWh a year, from modelled irradiation of 1,061 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 210 kWp array, sized to what the nearest school scheme on record applied for, 7 miles away at Whitehaven, models at about 175,400 kWh a year before shading, and needs roughly 624 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 45,600 kWh landing in July and August and roughly 6,100 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.

Workington ranks 3 of 6 towns we cover in Cumbria on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 793 to 893, a spread of 100 kWh per kWp. On a 500 kWp array that is about 50,000 kWh a year between the strongest and weakest town in the county.

The planning position for Workington schools

There is no school entry for the CA14 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 Workington.

The closest recorded one is about 7 miles away at Whitehaven: Whitehaven Academy, a 210 kWp roof mounted array applied for by The Whitehaven Academy, 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 Cumbria. Source: Renewable Energy Planning Database, Q1 2026.

Why demand in Workington falls as the roof peaks

The generating year and the school year are out of step in Workington. July and August carry 26 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 15.2 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 3.5 percent of output falls in December and January, the two months when a Workington school is fully occupied and its heating and lighting are at their heaviest. The roof makes 9.8 times as much in May as it does in December, and August alone outproduces December by about 7.6 to one. 77 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.

Summed over the year, about 49 percent of what a school roof makes arrives while the school is open. For a business trading every weekday the equivalent is roughly 71 percent. Nothing about Workington changes that ratio much, but plenty about your own site changes what to do with it.

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.

A Workington governing body should read that as a sizing constraint, not a reason to stop. The base load that runs through the holidays, servers, comms, refrigeration, ventilation and hot water, is the floor the array should be built up from, and everything above it has to be justified by storage, export or summer occupancy.

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.

Output per kWp installed, split by whether the day is a session day. July and August are 26 percent of the Workington year and the school is shut for most of them. Each month's total is spread evenly across its days, which is the only split available without half hourly readings. Session days follow a typical English school year of 190 days. Your own trust or authority may differ by a few days either way. Source: EU PVGIS v5.2, session days from a typical school calendar

The school estate in Cumberland

Cumberland has 171 open state-funded schools and colleges on the DfE register teaching 38,686 pupils between them. Source: DfE Get Information About Schools.

The split is 148 primary, 19 secondary, 3 special and 1 further education, at an average of 226 pupils a site. A ratio of 7.8 to one tells you where the roof area is. It is not with the 148 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 operates the distribution network across Cumbria, 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 Cumbria the planning database records 86 solar schemes totalling 574 MW, of which 17 are operational (REPD Q1 2026).
