Specialist solar panels for schools in Penrith
A kilowatt-peak on a Penrith school roof models at 794 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.
26.2% of the modelled year lands in July and August, on a roof that returns 794 kWh per kWp a year. The worked example below runs at 210 kWp, the size applied for at the nearest school scheme on record. 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.
Solar PV for academy trusts across Cumbria
A one kilowatt-peak array on a shallow pitched roof in Penrith models at 794 kWh a year, from modelled irradiation of 1,010 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 10 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, 34 miles away at Whitehaven, models at about 166,700 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 43,700 kWh landing in July and August and roughly 6,200 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.
Penrith ranks 5 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 Penrith schools
There is no school entry for the CA11 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 Penrith.
The closest recorded one is about 34 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 Penrith falls as the roof peaks
The generating year and the school year are out of step in Penrith. July and August carry 26.2 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 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 3.7 percent of output falls in December and January, the two months when a Penrith school is fully occupied and its heating and lighting are at their heaviest. The roof makes 9.2 times as much in May as it does in December, and August alone outproduces December by about 7.2 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.
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 Penrith changes that ratio much, but plenty about your own site changes what to do with it.
Then there is the afternoon. From roughly three o'clock the building empties while the roof is still working, so a system sized on annual consumption will over-generate in exactly the hours nobody is there. We size on half hourly data for that reason.
A Penrith 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.

The school estate in Westmorland and Furness
Westmorland and Furness has 147 open state-funded schools and colleges on the DfE register teaching 29,906 pupils between them. Source: DfE Get Information About Schools.
The split is 123 primary, 20 secondary, 3 special and 1 further education, at an average of 203 pupils a site. A ratio of 6.2 to one tells you where the roof area is. It is not with the 123 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 Cumbria the planning database records 86 solar schemes totalling 574 MW, of which 17 are operational (REPD Q1 2026).
Send us the school postcode
The first survey answers three questions at once: what the roofs carry, what they generate against your own timetable, and how a Penrith school pays for it. Send the postcode, an approximate roof area per block and half hourly meter data if the school can get it from its supplier.
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.
What Penrith trusts ask before a survey
- Is there enough sun around Penrith for this to be worth doing?
- The model gives 794 kWh a year for every kWp installed at this latitude, so a 210 kWp array comes out at roughly 166,700 kWh a year before shading. It needs about 624 square metres of clear roof once walkways and rooflight setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Does a Penrith school waste its generation in August?
- 26.2 percent of the modelled annual output for Penrith falls in July and August, when the buildings are closed for most of six weeks (EU PVGIS v5.2). It does not go to waste, but it only has three places to go: the base load that runs regardless, such as servers, catering refrigeration and ventilation; storage; or export under an agreement with Electricity North West. We model all three against your half hourly data before an array is sized.
- Will the network around Penrith accept the export?
- Electricity North West is the distribution network operator for Cumbria. Anything above 3.68 kW per phase connects under G99, and the application fixes the export limit. On a school site the incoming supply is often the binding constraint rather than the roof, so we ask that question before anyone sizes an array.
- Is planning permission needed for panels on a school in Penrith?
- Usually permitted development covers a roof array on a school, with prior approval from Eden needed above a capacity threshold. A ground mounted array in the grounds is a different question and much more likely to need a full application. We check both before design sign-off.
- How many schools are there around Penrith?
- Westmorland and Furness has 147 open state-funded schools and colleges on the DfE register, with 29,906 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.
