What solar actually does in Dumbarton
Jonathan holds the OVO Solar & Battery partnership for Clyde and Ayrshire, and Dumbarton sits inside their G postcode patch. You deal with a named local expert, the design happens on a free 45 minute video call, and nobody visits your home until you have decided to go ahead. PVGIS puts Dumbarton at 856 kWh per kWp a year, so a 14 panel (6.3 kWp) system here generates around 5,393 kWh a year.
Yield and peak sun hours are PVGIS estimates for Dumbarton's own coordinates, not a regional average. Your free design refines them for your actual roof.

Straight answers from the OVO Solar and Battery team, sourced and dated.
How solar panels work, and why they work here
Panels run on daylight, not heat. What happens between your roof and your meter.
Read the guide →Single phase or three phase, and what it changes
One fuse or three. The check takes a minute and it sets your system size limit.
Read the guide →Adding a battery to solar you already have
Your panels stay untouched. The grid application is the part that catches people out.
Read the guide →What a gateway does, and when whole home backup is worth it
A full battery is no use in a power cut without a gateway. Here is what one does.
Read the guide →The 20p export rate, and how it compares to standard SEG
4p or 20p for the same exported units. The conditions on each, in plain terms.
Read the guide →The energy price cap, and what it does to your solar payback
The cap sets your unit price. That price is what every unit of your own solar is worth.

Generation figures are PVGIS v5.2 estimates retrieved August 2026 for the coordinates of Dumbarton, assuming a south-facing roof at a 35 degree pitch with no significant shading, the same assumptions as the regional figures on this site. Population is the House of Commons Library settlement classification figure. Your free design accounts for your actual orientation, pitch and shading.
