Solar panels for warehouses in Thame

Sheds around Thame tend to have more roof than the business has any other use for. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.

What a roof in Thame actually generates

Modelled irradiation at this latitude is 1142 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 891 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.

We survey across the OX postcode area, starting from OX9.

South Oxfordshire is the planning authority for most sites here, and the built-up area holds a population of about 12,945, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).

Jun produces 6.2 times what Dec does on the same roof. A 500 kWp array here models at about 446,000 kWh across the year, but it arrives unevenly, which is why we size against your summer daytime load and then look at whether storage is worth adding for the shoulder months.

Thame ranks 8 of 8 towns we cover in Oxfordshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 891 to 913, a spread of 22 kWh per kWp. Within Oxfordshire that difference is small enough to ignore: where the building sits is not what decides this scheme, your consumption pattern is.

Bars are zero based, so length is proportional to the figure. Where a county is flat, that is the finding: location is not the lever, consumption is. Source: EU PVGIS v5.2, modelled per town

Grid connection through Scottish and Southern Electricity Networks

Scottish and Southern Electricity 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 Oxfordshire the planning database records 149 solar schemes totalling 2544 MW, of which 31 are operational (REPD Q1 2026).

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.

Questions about solar in Thame

Is there enough sun in Thame to make this work?
Modelled at 891 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 446,000 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 Thame?
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 South Oxfordshire?
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 South Oxfordshire first either way.
Has anyone near OX9 already done this?
The planning database records 6 solar schemes in this postcode district. 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.
