Farm solar panels across Gwynedd
We survey farm and agricultural building roofs throughout Gwynedd, model what each one can carry, and arrange the design, the grid application and the install through our MCS-certified partner.

What the data says about Gwynedd
Modelled yield is not flat across Gwynedd. Pwllheli comes out at 887 kWh per kWp a year against 704 at Bethesda, a spread of 183 kWh per kWp. On a 200 kWp farm array that difference is about 36,600 kWh a year, which is worth checking before accepting a generic saving figure.
The planning record lists no solar schemes for the districts we cover in Gwynedd. On agricultural land that usually reflects the reporting threshold rather than an absence of arrays, because roof mounted schemes on farm buildings seldom appear in it.
Connections across the county run through SP Energy Networks. Anything above 3.68 kW per phase needs a G99 application, and on rural feeders the incoming supply is often the real limit: a single phase supply caps the array whatever the roof would carry.
- Bangor 733 kWh/kWp
- Bethesda 704 kWh/kWp
- Caernarfon 798 kWh/kWp
- Dolgellau 746 kWh/kWp
- Porthmadog 820 kWh/kWp
- Pwllheli 887 kWh/kWp
