What solar actually does in Annan
Gregor holds the OVO Solar & Battery partnership for South West Scotland, and Annan sits inside their DG 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 Annan at 929 kWh per kWp a year, so a 14 panel (6.3 kWp) system here generates around 5,853 kWh a year.
Yield and peak sun hours are PVGIS estimates for Annan's own coordinates, not a regional average. Your free design refines them for your actual roof.

Worth reading before your Annan design call
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 →What to check before switching supplier when you have solar
Four checks before you switch: your export condition, your MCS pack, your meter and any Feed-in Tariff.
Read the guide →Why your tariff moves payback more than your kit does
Same install, three export rates, seven years of difference in payback.

Generation figures are PVGIS v5.2 estimates retrieved August 2026 for the coordinates of Annan, 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.
