What solar actually does in Southwark
Roofs in Southwark come in every shape: terraces, semis and detached streets, often on the same road. That variety is what the remote design process is built for. Aine's team looks at your actual roof on satellite and aerial imagery, live on a free 45 minute video call, and sizes the system to it. PVGIS puts Southwark at 1,029 kWh per kWp a year, so a full 14 panel (6.3 kWp) roof here generates around 6,483 kWh a year.
Yield and peak sun hours are PVGIS estimates for Southwark's own coordinates, not a regional average. Your free design refines them for your actual roof.

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