Specialist solar panels for schools in Wallasey
A kilowatt-peak on a Wallasey school roof models at 862 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.
862 kWh per kWp a year at this latitude, so a 380 kWp array, the size applied for at the nearest school scheme on record, models at about 327,600 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.
Solar PV for academy trusts across Merseyside
A one kilowatt-peak array on a shallow pitched roof in Wallasey models at 862 kWh a year, from modelled irradiation of 1,098 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 3 percent below the mean across the towns we cover, which is a smaller gap than most schools expect and smaller than the gap between a well matched and a badly matched system.
Scaled up, a 380 kWp array, sized to what the nearest school scheme on record applied for, 13 miles away at St Helens, models at about 327,600 kWh a year before shading, and needs roughly 1,129 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 83,900 kWh landing in July and August and roughly 13,800 kWh across December and January. SP Energy Networks 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.
Wallasey ranks 2 of 6 towns we cover in Merseyside on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 830 to 877, a spread of 47 kWh per kWp. On a 500 kWp array that is about 23,500 kWh a year between the strongest and weakest town in the county.
The planning position for Wallasey schools
There is no school entry for the CH44 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 Wallasey.
The closest recorded one is about 13 miles away at St Helens: The Sutton Academy, Elton Head Road, a 380 kWp roof mounted array applied for by Located Property Limited, 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 Merseyside. Source: Renewable Energy Planning Database, Q1 2026.
Why demand in Wallasey falls as the roof peaks
The generating year and the school year are out of step in Wallasey. July and August carry 25.6 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 14.4 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 4.2 percent of output falls in December and January, the two months when a Wallasey school is fully occupied and its heating and lighting are at their heaviest. 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.
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 Wallasey changes that ratio much, but plenty about your own site changes what to do with it.
The same mismatch repeats every day. Peak generation lands between eleven and three, the timetable ends shortly after, and by four the site is down to caretaking and cleaning. An annual consumption figure cannot show that, which is why we ask for the half hourly data instead.
A Wallasey 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 Wirral
Wirral has 125 open state-funded schools and colleges on the DfE register teaching 49,098 pupils between them. Source: DfE Get Information About Schools.
The split is 93 primary, 20 secondary, 10 special and 2 further education, at an average of 393 pupils a site. A ratio of 4.7 to one tells you where the roof area is. It is not with the 93 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 SP Energy Networks
SP Energy Networks 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 Merseyside the planning database records 104 solar schemes totalling 98 MW, of which 1 are operational (REPD Q1 2026).
Send us the school postcode
Lenzie Consulting Ltd arranges roof surveys for schools across Merseyside. Send the school postcode and a rough idea of the roof area, and the last twelve months of half hourly meter data if the school holds it. We come back with what the roofs can carry, what they would generate against your own consumption, and the funding routes open to a school.
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 Wallasey trusts ask before a survey
- What would a 380 kWp array produce at a Wallasey school?
- Yes, and the figure matters more than the sunshine. 862 kWh per kWp a year puts a 380 kWp array at around 327,600 kWh, on roughly 1,129 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 Wallasey?
- Less is wasted than governors expect, but the figure is worth seeing: 25.6 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 SP Energy Networks.
- Who do we apply to for export near Wallasey?
- Only SP Energy Networks 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 Wirral?
- 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 Wirral. We confirm it either way.
- How many schools are there around Wallasey?
- Wirral has 125 open state-funded schools and colleges on the DfE register, with 49,098 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.
