Solar panels for warehouses in Berwick-upon-Tweed
Most of the industrial stock around Berwick-upon-Tweed carries a large, shallow-pitched roof that was never asked to do anything. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.
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.

What a roof in Berwick-upon-Tweed actually 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 towns we cover, so the case here leans harder on how much you use on site rather than on raw generation.
We survey across the TD postcode area, starting from TD15.
Northumberland is the planning authority for most sites here, and the built-up area holds a population of about 13,175, so the stock here runs to trade counters, light industrial terraces and the occasional larger shed (ONS Census 2021 built-up areas).
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.

| 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 in Berwick-upon-Tweed?
- Yes, and the number matters more than the sunshine. At 827 kWh per kWp a year, a 500 kWp array on a Berwick-upon-Tweed roof models at around 414,000 kWh. What changes the answer is how much of that you use on site rather than export. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Which network operator handles the connection in Berwick-upon-Tweed?
- Applications go to Northern Powergrid, who run the network across Northumberland. They decide the export limit, and we handle the G99 paperwork alongside the array design.
- What does Northumberland require for rooftop solar?
- Roof-mounted panels on a commercial building usually fall under permitted development, subject to the limits on projection above the roof plane and to the building not being listed or in a conservation area. We confirm the position with Northumberland before the design is finalised.
- Has anyone near TD15 already done this?
- The planning database records 2 solar schemes in this postcode district, 2 of them roof mounted. That matters less as proof that it works and more as evidence of how the local network has been treating export applications. Source: Renewable Energy Planning Database, Q1 2026.
