Solar panels for farms in Cardiff City Centre

The case for solar on a Cardiff City Centre holding turns on how much of the output the farm uses itself, not on how much the roof makes. What decides a farm scheme here is the state of the roof sheets and the incoming supply, which is why the survey looks at both before anyone sizes an array.

Agricultural rooftop solar across Cardiff

No solar scheme is recorded in this postcode district in the planning database. On a farm that usually means nothing has been built above the reporting threshold rather than that nothing has been built, because a roof array on a shed rarely appears in it.

Cardiff City Centre 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

Connections around Cardiff City Centre are handled by National Grid Electricity Distribution, which sets the export limit for the site. Above 3.68 kW per phase the connection runs under G99, so the export limit is agreed in advance rather than assumed. Where the local network is constrained, an export-limited connection usually still makes the scheme work, because a farm uses most of what the roof makes during the working day.
