Commercial building solar panels in Newcastle
For a landlord in Newcastle, a roof array is increasingly a question about the EPC rating as much as the electricity bill. Each survey records the usable area once edge strips, plant and walkways are taken out, the load the deck can take, and whether the lease lets the occupier alter the roof.
806 kWh per kWp a year at this latitude, so a 210 kWp array models at about 169,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Solar for offices and retail across Tyne and Wear
How much sun a Newcastle roof gets
Modelled irradiation here is 1,026 kWh per square metre a year on a low-tilt array, which works out at 806 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is about 9 percent below the mean across the towns we cover, so the case here rests more on daytime consumption than on raw generation.
Newcastle ranks 6 of 6 towns we cover in Tyne and Wear on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 806 to 849, a spread of 43 kWh per kWp. On a 210 kWp commercial roof that is about 9,030 kWh a year between the strongest and weakest town in the county.
Grid connection through Northern Powergrid
Northern Powergrid is the network operator here, and their answer on export capacity shapes the design. Any commercial array above 3.68 kW per phase connects under G99 rather than G98, and the application fixes what you are allowed to push back onto the network. If the local network is tight, limiting export rarely breaks the case here: most of the generation is consumed on site while the building is working.
Across Tyne and Wear the planning database records 116 solar schemes totalling 290 MW, of which 3 are operational (REPD Q1 2026).

Questions about solar in Newcastle
- How much would solar on a commercial building in Newcastle generate?
- The model gives 806 kWh for every kWp installed here, so 210 kWp is about 169,000 kWh a year before shading losses. Allow roughly 1,390 m² of roof for it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Is planning permission needed for panels on a Newcastle office or shop?
- Usually not a full application. In England, panels on the roof of a non-domestic building are permitted development under Class J of Part 14 of the General Permitted Development Order, with no capacity cap since December 2023. Above 50 kW, which covers most commercial arrays, you must first apply to Tyne and Wear for a determination on prior approval of the design and appearance, in particular glare on neighbouring land. On a flat roof panels may stand no more than 1 metre above the roof and must sit at least 1 metre from its edge, and listed buildings and scheduled monuments are excluded. See our planning permission guide for the detail.
- Does the grid around Newcastle have capacity for export?
- Northern Powergrid is the distribution network operator for Tyne and Wear. Arrays above 3.68 kW per phase connect under G99, and the application sets the export limit. It is part of the design work we arrange.
