What solar actually does in Harrow

Roofs in Harrow 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. Scott'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 Harrow at 1,026 kWh per kWp a year, so a full 14 panel (6.3 kWp) roof here generates around 6,464 kWh a year.

Yield and peak sun hours are PVGIS estimates for Harrow's own coordinates, not a regional average. Your free design refines them for your actual roof.

Two minutes. We confirm your video slot within one working day.

We can only install for homeowners, as the system is fixed to the property. Do carry on if you own it, or you are about to.
We are not able to install on flats and apartments because the roof is shared. Send your details anyway and we will let you know if that changes.

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