Solar panels for warehouses in Cardiff Bay

The economics of a Cardiff Bay rooftop array turn on how much of the generation the occupier uses on site. Each survey records the cladding profile, the usable area once rooflights and plant are removed, and the export limit worth applying for.

Cardiff Bay ranks 0 of 4 towns we cover in Cardiff on modelled yield, against a national mean of 886 kWh per kWp. The county runs from 908 to 936, a spread of 28 kWh per kWp. Within Cardiff 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 Cardiff, 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.

Who do we apply to for export in Cardiff Bay?
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.
