Is there enough sun around Sherborne to make this work?

Modelled at 924 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 462,000 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 Sherborne?

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 Dorset?

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 Dorset either way.

Has anyone near DT9 already done this?

The planning database records 5 ground mounted and 0 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.

Solar panels for farms in Sherborne

A Sherborne farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. Each survey records the sheet type and condition, the usable area once rooflights and vents come out, and whether the supply is single or three phase.

924 kWh per kWp a year at this latitude, so a 500 kWp array models at about 462,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Sherborne generates

Modelled irradiation at this latitude is 1182 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 924 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 4 percent above the mean across the areas we cover, which is as strong as UK farm rooftop gets outside the south coast.

The planning record lists 5 ground mounted solar schemes 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 6.7 MW, with the largest at 40 MW. Source: Renewable Energy Planning Database, Q1 2026.

We survey holdings across the DT postcode area, starting from DT9.

Dorset 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.

FIG. 1 What a Sherborne roof makes, month by month

Jul produces 5.8 times what Dec does on the same roof. A 500 kWp array here models at about 462,000 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.

Sherborne ranks 8 of 8 towns we cover in Dorset on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 924 to 1006, a spread of 82 kWh per kWp. On a 500 kWp array that is about 41,000 kWh a year between the strongest and weakest town in the county.

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

Connections around Sherborne 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 Dorset the planning database records 149 solar schemes totalling 1078 MW, of which 47 are operational (REPD Q1 2026).
