Solar panels for warehouses in Maidenhead
What makes a Maidenhead scheme work is rarely the panels. It is the condition of the roof underneath them. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
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.

What a roof in Maidenhead actually 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 towns we cover, so the case rests on your consumption pattern rather than on the weather.
Distribution stock around Maidenhead clusters on M4 J8/9, A404(M) and A4, which is where the large single-let roofs are.
Surveys run across SL postcodes, SL6 outward.
Windsor and Maidenhead is the planning authority for most sites here, and the built-up area holds a population of about 67,375, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
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 warehouse 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 in 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 walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Maidenhead?
- Capacity varies street by street, and only Scottish and Southern Electricity Networks can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
- Do we need planning permission in Windsor and Maidenhead?
- In most cases no, because roof-mounted panels on commercial buildings sit within permitted development. The exceptions are listed buildings, conservation areas and arrays that stand proud of the roof plane. We check with Windsor and Maidenhead first either way.
- Has anyone near SL6 already done this?
- The planning database records 4 solar schemes in this postcode district, 4 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
