Residential rooftops across London and surrounding areas were remotely assessed for solar suitability using roof orientation, area and shading analysis.
The challenge
Manual surveying could not assess enough residential buildings quickly enough to support large-scale solar rollout.
Only roofs with suitable orientation and limited shading could support the expected energy yield.
The approach
SBL defined ideal roof criteria and used Google Earth, Google Maps and Roofray to assess residential suitability remotely.
The team cross-checked roof geometry, sun exposure and shading constraints before preparing a qualified site database.
Define
Set suitability criteria for roof slope, orientation and shade.
Assess
Use map and solar tools to qualify residential rooftops remotely.
Prioritize
Prepare a database of high-probability solar installation sites.
The result
The program reduced manual fieldwork and gained a faster path to identify ready-to-install residential solar sites.
- Remote analysis reduced manual surveying by about 90%.
- South-facing and shade-free rooftops were prioritized.
- Multiple mapping tools supported roof area and exposure review.
- The output helped accelerate residential solar planning.
