Warehouse solar panels across Gwynedd
We survey industrial and distribution 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 500 kWp array that difference is about 91,500 kWh a year, which is worth checking before you accept a generic saving figure.
The government's planning database records 19 solar schemes in Gwynedd totalling 221 MW, of which 6 are already operational. Source: Renewable Energy Planning Database, Q1 2026.
Connections across the county run through SP Energy Networks. Anything above 3.68 kW per phase needs a G99 application, and the export limit they offer shapes the design, so we ask the question before the array is sized rather than after.
- Bangor 733 kWh/kWp
- Bethesda 704 kWh/kWp
- Caernarfon 798 kWh/kWp
- Dolgellau 746 kWh/kWp
- Porthmadog 820 kWh/kWp
- Pwllheli 887 kWh/kWp
