Specialist solar panels for schools in West Bromwich
National Grid Electricity Distribution runs the network around West Bromwich, and on a school site their answer on export shapes the design as much as the roof pitch does. We look at the roof, the switchboard and the timetable in that order, then set the array size against what the site draws in term time.
25.7% of the modelled year lands in July and August, on a roof that returns 852 kWh per kWp a year. The worked example below runs at 370 kWp, the median size schools across West Midlands have applied for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Book a roof survey in West Bromwich- 1 teaching block

- 4 1960s block, no array
- first phase
- later phase
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.
School rooftop solar across West Midlands
A one kilowatt-peak array on a shallow pitched roof in West Bromwich models at 852 kWh a year, from modelled irradiation of 1,091 kWh per square metre in the plane of the array (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). West Bromwich sits 4 percent under our mean. Worth knowing, but not decisive: how well the array matches the timetable moves the answer further than the latitude does.
Scaled up, a 370 kWp array, sized to the median array applied for at schools across West Midlands, models at about 315,200 kWh a year before shading, and needs roughly 1,099 square metres of clear roof. We use that size because it is what schools across West Midlands have applied for, not because it suits the arithmetic.
Spread across the year that is about 81,000 kWh landing in July and August and roughly 15,800 kWh across December and January. National Grid Electricity Distribution 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.
West Bromwich ranks 4 of 8 towns we cover in West Midlands on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 839 to 868, a spread of 29 kWh per kWp. Within West Midlands that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
What the planning record shows around West Bromwich
There is no school entry for the B71 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 West Bromwich.
The nearest education scheme on the record is 6 miles from West Bromwich, at Birmingham: 0 kWp at Eden Boys Leadership Academy, Alum Rock Road, applicant Star Academies, which holds consent and is awaiting construction. That is someone else's application, not ours, and it is here because it shows what West Midlands planning has already accepted at an education site.

The summer holiday problem for a West Bromwich school
25.7 percent of the annual output modelled for West Bromwich arrives in the two months a school uses least (EU PVGIS v5.2). Term ends in the third week of July and the buildings stay largely empty until September. July is the single strongest month here at 14 percent of the annual total, and it falls almost entirely inside the holiday.
The inverse holds at the other end. December and January together return only 5 percent of the year, and those are the months with the heating, the lighting and the full timetable all running at once. The roof makes 6 times as much in July as it does in December, and August alone outproduces December by about 5 to one. 74 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.
Across the country the arithmetic settles at roughly 49 percent of output on a session day, against about 71 percent for a weekday business. That figure hardly varies by location, which is why the local numbers that matter here are the yield, the roofs and what has already cleared planning nearby.
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.
That argues for a particular shape of scheme rather than against one. Size to the load that does not stop at the end of term, count in lettings, holiday clubs and summer works honestly rather than optimistically, and then decide whether storage or an export arrangement with National Grid Electricity Distribution pays for the surplus that is left.

Grid connection through National Grid Electricity Distribution
National Grid Electricity Distribution operates the distribution network across West Midlands, 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 West Midlands the planning database records 195 solar schemes totalling 533 MW, of which 3 are operational (REPD Q1 2026).
How many schools Sandwell has
Sandwell has 121 open state-funded schools and colleges on the DfE register teaching 62,009 pupils between them. Source: DfE Get Information About Schools.
The split is 93 primary, 22 secondary, 5 special and 1 further education, at an average of 512 pupils a site. A ratio of 4.2 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.
Start with the West Bromwich roof
A survey in West Bromwich starts with three things from you. Give us the postcode, the approximate roof area and, if you can get it from your supplier, twelve months of half hourly readings. What comes back is a usable area figure per block, output modelled against your own load rather than an average, and the ways a West Bromwich school can pay for it.
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.
Questions governors ask us about West Bromwich schools
- How much would a school roof near West Bromwich generate?
- Modelled at 852 kWh per kWp a year, a 370 kWp array on a West Bromwich school models at about 315,200 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 West Bromwich?
- It goes somewhere, just not into the timetable. 25.7 percent of the West Bromwich 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 National Grid Electricity Distribution, or a sign the array is too big. We test which before sizing anything.
- Which network operator handles the connection at a West Bromwich school?
- Applications go to National Grid Electricity Distribution, who run the network across West Midlands. 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 Birmingham 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 Birmingham on siting and design. Listed buildings and conservation areas are the usual exceptions. We put the position to Birmingham before a design is finalised.
- How many schools are there around West Bromwich?
- Sandwell has 121 open state-funded schools and colleges on the DfE register, with 62,009 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.
