Solar Potential Assessment


How does Blom Solar Potential Mapping work?

The basis of the solar map is a detailed 3D representation of the study area known as a Digital Surface Model, or DSM. Building footprints are used to identify the areas of the DSM which represent a building roof and each one is given a unique reference number.

The roof of each building is broken down into smaller surface elements to increase calculation accuracy. The amount of solar radiation received by each surface element is then calculated at intervals of one hour taking into account:

  • Orientation and pitch of the surface element
  • Daily and annual transit of the sun
  • The shadowing effect of any object that comes temporarily or permanently between the surface element and the moving sun

Blom Solar Potential Mapping generates accurate estimates of:

  • Annual solar radiation received (direct and diffuse)
  • Total suitable roof area of each property
  • Annual electrical power output
  • Annual CO₂ emission reductions
  • Return on investment over the installation lifespan

Key benefits include:

  • Online delivery via Web based GIS to the public and property owners
  • Raised awareness and uptake of solar technology
  • Contribute to CO₂ reduction targets
  • Reduces the number of costly site visits and associated travel
  • Reduced marketing costs - Target only suitable properties
