Solar GHI Maps of Alberta and BC, Canada

Global Horizontal Solar Irradiation   for Alberta and BC.

  • Derived from SUNY hourly satellite data from 2002 to 2008  ( 10 km x 10 km area)
  • GHI = Global Irradiation on a horizontal surface in  kWh/m2/yr
  • GHI contains both direct and diffuse energy.
  • Tilted PV arrays  or sun tracking systems will yield higher energy value  than a horizontal surface.  GHI is not representative of PV potential, specially in high latitudes.
