DNV’s GeoWeb - Solar Application
•
Developed last year with DNV GIS Department
and UBC School of Forestry (Rory Tooke – PhD.
Project)
•
Uses LiDAR (Light Detection and Ranging) data
•
Application allows residents to see how much
sunlight hits each square metre of their roof
•
Very precise – takes into account slope of
individual roof, orientation, location of trees and
other buildings, sun movement, etc.

Lessons Learned
•
Use third party to develop appropriate system specifications
•
Look at broad scope of factors when deciding what type of
system to install:
•
•
•
O&M costs
Maintenance environment, etc
Consider benefits of using one type of system and one installer
•
For best business case – group several installations
•
Scale of installations is important when deciding which
consultants need to be involved
•
Costs are reduced on new developments vs. retrofits
Next steps
•
Solar Installations on new municipal facilities
•
Use GeoWeb & solar demo unit to:
- Support solar installations on new residential
- Support solar retrofits
- Educate Residents
