Solar panels for farms in Alnwick
The case for solar on a Alnwick holding turns on how much of the output the farm uses itself, not on how much the roof makes. 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.
840 kWh per kWp a year at this latitude, so a 500 kWp array models at about 420,000 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 Alnwick generates
Modelled irradiation at this latitude is 1066 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 840 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 5 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.
No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.
Alnwick ranks 2 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.
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 Alnwick
- Is there enough sun around Alnwick to make this work?
- Modelled at 840 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 420,000 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 Alnwick?
- 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.
