Solar panels for farms in St Ives

A St Ives 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.

906 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 farm roof near St Ives 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 906 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 4 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 4.1 MW, with the largest at 6.8 MW. Source: Renewable Energy Planning Database, Q1 2026.

1 roof mounted scheme is on record nearby. Roof arrays under a megawatt frequently never reach that database at all, so the real number of farm roofs generating around St Ives is higher than the record shows.

We survey holdings across the PE postcode area, starting from PE27.

Huntingdonshire 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.

Jun produces 5.6 times what Dec does on the same roof. A 500 kWp array here models at about 453,000 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.

St Ives ranks 3 of 8 towns we cover in Cambridgeshire on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 898 to 908, a spread of 10 kWh per kWp. Within Cambridgeshire 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 UK Power Networks

UK Power Networks operates the distribution network across Cambridgeshire, 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 Cambridgeshire the planning database records 172 solar schemes totalling 2422 MW, of which 46 are operational (REPD Q1 2026).

Questions about solar in St Ives

Is there enough sun around St Ives to make this work?
Modelled at 906 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 St Ives?
Only UK Power 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 Huntingdonshire?
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 Huntingdonshire either way.
Has anyone near PE27 already done this?
The planning database records 4 ground mounted and 1 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.
