Solar panels for farms in Slough
Most holdings around Slough already own the best generating site they will ever have, and it is the roof of the shed they built for something else. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.
903 kWh per kWp a year at this latitude, so a 500 kWp array models at about 452,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Agricultural rooftop solar across Berkshire
What a farm roof near Slough generates
Modelled irradiation at this latitude is 1160 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 903 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the areas we cover, so what decides the scheme is your own demand pattern rather than the latitude.
3 roof mounted schemes are on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around Slough is higher than the record shows.
Most of the buildings we look at here sit in the SL postcode area.
Slough is the planning authority for most holdings here, and it is the authority that decides whether an array on an agricultural building falls inside permitted development.
Slough ranks 5 of 8 towns we cover in Berkshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 891 to 910, a spread of 19 kWh per kWp. Within Berkshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.
Solar already consented near SL1
From the government's Renewable Energy Planning Database, Q1 2026. These are the schemes on record in this postcode district, which is a fair guide to how the local network has been treating export applications.
| Scheme | Operator | Capacity | Mounting | Status |
|---|---|---|---|---|
| Galvin Road | Barclays Bank / Innogy (previously BELECTRIC Solar) | 1.6 MW | Roof | Abandoned |
| Twinches Lane - Solar photovoltaic | Orchard Street Investment Management LLP | 0.32 MW | Roof | Awaiting Construction |
| Unit 2a, Slough Retail Park - Solar Panels | Sofology Head Office | 0.19 MW | Roof | Awaiting Construction |
Grid connection through Scottish and Southern Electricity Networks
Scottish and Southern Electricity Networks operates the distribution network across Berkshire, 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 Berkshire the planning database records 83 solar schemes totalling 317 MW, of which 8 are operational (REPD Q1 2026).

Questions about solar in Slough
- What would a 500 kWp array produce on a farm near Slough?
- Yes, and the figure matters more than the sunshine. At 903 kWh per kWp a year, a 500 kWp array on a Slough holding models at around 452,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Slough?
- Applications go to Scottish and Southern Electricity Networks, who run the network across Berkshire. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Slough require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Slough before the design is finalised.
- Has anyone near SL1 already done this?
- The planning database records 0 ground mounted and 3 roof mounted solar schemes in this postcode district. That matters less as proof it works and more as evidence of how the local network has treated export applications. Roof arrays under a megawatt often never appear in the database, so the real figure is higher. Source: Renewable Energy Planning Database, Q1 2026.
