Solar panels for warehouses in Sketty

Most of the industrial stock around Sketty 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.

921 kWh per kWp a year at this latitude, so a 500 kWp array models at about 461,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

What a roof in Sketty actually generates

Modelled irradiation at this latitude is 1176 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 921 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That is around 4 percent above the mean across the towns we cover, which is as good as UK rooftop gets outside the south coast.

Jun produces 6.5 times what Dec does on the same roof. A 500 kWp array here models at about 461,000 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.

Sketty ranks 2 of 4 towns we cover in Swansea on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 881 to 921, a spread of 40 kWh per kWp. Within Swansea 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 National Grid Electricity Distribution

National Grid Electricity Distribution operates the distribution network across Swansea, 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.

Questions about solar in Sketty

How much does a warehouse roof in Sketty generate?
The model gives 921 kWh for every kWp installed here, so 500 kWp comes out at about 461,000 kWh a year before any shading losses. You need roughly 1,485 sqm of clear roof to fit it. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
Does the grid around Sketty have capacity?
National Grid Electricity Distribution is the distribution network operator for Swansea. Anything above 3.68 kW per phase connects under G99, and the application sets the export limit. We submit it as part of the design.
