Is there enough sun around Bishop Auckland to make this work?

Modelled at 817 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 409,000 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 Bishop Auckland?

Only Northern Powergrid 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 County Durham?

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 County Durham either way.

Has anyone near DL14 already done this?

The planning database records 0 ground mounted and 6 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 Bishop Auckland

A Bishop Auckland farm buys electricity at the worst rate of the day in exactly the hours its roof could be generating. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.

817 kWh per kWp a year at this latitude, so a 500 kWp array models at about 409,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a farm roof near Bishop Auckland generates

Modelled irradiation at this latitude is 1042 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 817 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 8 percent below the mean across the areas we cover, so the case here rests on using the output on the holding rather than exporting it.

6 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 Bishop Auckland is higher than the record shows.

Most of the buildings we look at here sit in the DL postcode area.

County Durham 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 Bishop Auckland roof makes, month by month

May produces 7.8 times what Dec does on the same roof. A 500 kWp array here models at about 409,000 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.

Bishop Auckland ranks 5 of 6 towns we cover in County Durham on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 811 to 845, a spread of 34 kWh per kWp. Within County Durham 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 Northern Powergrid

Northern Powergrid operates the distribution network across County Durham, 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 County Durham the planning database records 85 solar schemes totalling 1168 MW, of which 9 are operational (REPD Q1 2026).
