Solar panels for warehouses in Morriston
Roof space is the one asset a Morriston unit already owns and rarely uses. We start with the covering and the structure, because a roof with five years left in it changes the answer entirely.
899 kWh per kWp a year at this latitude, so a 500 kWp array models at about 450,000 kWh. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.

Warehouse rooftop solar across Swansea
What a roof in Morriston actually generates
Modelled irradiation at this latitude is 1147 kWh per square metre a year in the plane of a shallow-pitched roof, which works out at 899 kWh for every kWp installed (EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss). That sits within a few percent of the mean across the towns we cover, so the case rests on your consumption pattern rather than on the weather.
Morriston ranks 3 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.
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.

Tell us where the unit is and roughly how big the roof is. We come back with what it can carry, what it would generate against your consumption, and the three ways to pay for it.
Lenzie Consulting Ltd arranges the survey and passes your details to our MCS-certified installation partner so they can quote.
Questions about solar in Morriston
- Is there enough sun in Morriston to make this work?
- Modelled at 899 kWh per kWp a year for a shallow-pitched roof at this latitude, which puts a 500 kWp array at roughly 450,000 kWh a year before shading. That array needs about 1,485 sqm of clear roof once walkways and setbacks are allowed for. Source: EU PVGIS v5.2, SARAH3, 10 degree pitch, 14 percent system loss.
- Who do we apply to for export in Morriston?
- Capacity varies street by street, and only National Grid Electricity Distribution can answer it for your connection. We ask the question early, because an export-limited offer changes the design rather than killing the scheme.
