Solar panels for farms in Berwick-upon-Tweed
Most holdings around Berwick-upon-Tweed already own the best generating site they will ever have, and it is the roof of the shed they built for something else. 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.
827 kWh per kWp a year at this latitude, so a 500 kWp array models at about 414,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Farm building solar PV across Northumberland
What a farm roof near Berwick-upon-Tweed generates
Modelled irradiation at this latitude is 1049 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 827 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 7 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.
2 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 Berwick-upon-Tweed is higher than the record shows.
We survey holdings across the TD postcode area, starting from TD15.
Northumberland 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.
Berwick-upon-Tweed ranks 3 of 6 towns we cover in Northumberland on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 803 to 848, a spread of 45 kWh per kWp. On a 500 kWp array that is about 22,500 kWh a year between the strongest and weakest town in the county.

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.
| Scheme | Operator | Capacity | Mounting | Status |

| Castle Hills Farm, Castle Hills - Solar Panels | D And S Macpherson | n/a | Roof | Awaiting Construction |
Grid connection through Northern Powergrid
Northern Powergrid operates the distribution network across Northumberland, 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 Northumberland the planning database records 38 solar schemes totalling 276 MW, of which 2 are operational (REPD Q1 2026).

Questions about solar in Berwick-upon-Tweed
- What would a 500 kWp array produce on a farm near Berwick-upon-Tweed?
- Yes, and the figure matters more than the sunshine. At 827 kWh per kWp a year, a 500 kWp array on a Berwick-upon-Tweed holding models at around 414,000 kWh. What changes the answer is how much of that the farm uses itself. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection around Berwick-upon-Tweed?
- Applications go to Northern Powergrid, who run the network across Northumberland. On a farm the incoming supply matters as much as their answer: a single phase supply caps what can be installed whatever the roof would take.
- What does Northumberland require for solar on an agricultural building?
- Roof-mounted panels on an agricultural building often fall under permitted development, subject to limits on projection above the roof plane and to the building not being listed or in a conservation area or National Park. We confirm the position with Northumberland before the design is finalised.
- Has anyone near TD15 already done this?
- The planning database records 0 ground mounted and 2 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.
