Solar panels for farms in Maidenhead
A Maidenhead farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. The survey starts on the covering: fibre cement or steel, its remaining life, the purlin spacing and what the frame will carry.
905 kWh per kWp a year at this latitude, so a 500 kWp array models at about 453,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for agricultural buildings across Berkshire
What a farm roof near Maidenhead generates
Modelled irradiation at this latitude is 1162 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 905 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.
The planning record lists 1 ground mounted solar scheme in this postcode district, which is a fair guide to how the local network has treated field arrays. The typical consented scheme in this district is about 1.3 MW, with the largest at 1.33 MW. Source: Renewable Energy Planning Database, Q1 2026.
4 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 Maidenhead is higher than the record shows.
Surveys run across SL postcodes, SL6 outward.
Windsor and Maidenhead 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.
Maidenhead ranks 3 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.

Grid connection through Scottish and Southern Electricity Networks
Connections around Maidenhead are handled by Scottish and Southern Electricity Networks, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a farm uses most of what the roof makes during the working day.
Across Berkshire the planning database records 83 solar schemes totalling 317 MW, of which 8 are operational (REPD Q1 2026).

Questions about solar in Maidenhead
- Is there enough sun around Maidenhead to make this work?
- Modelled at 905 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 453,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once ridge vents and walkways are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export near Maidenhead?
- Only Scottish and Southern Electricity Networks can answer it for your connection, and on rural feeders the answer varies farm to farm. An export-limited offer usually still works, because a holding with grain drying, cooling or ventilation uses most of what it makes.
- Do we need planning permission in Windsor and Maidenhead?
- In most cases no, because panels on the roof of an agricultural building usually sit within permitted development. The exceptions are listed buildings, conservation areas, protected landscapes and arrays that stand proud of the roof. We check with Windsor and Maidenhead either way.
- Has anyone near SL6 already done this?
- The planning database records 1 ground mounted and 4 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.
