The primary purpose of this Web Map is to present accurate estimations of the
monthly and annual solar insolation for locations throughout British Columbia.
This dataset was generated using an empirical solar heat gain calculation that assumes clear skies.
The data was generated by applying my python module to geographical points. The points are from
BC Geographical Names layer. The topographical information is from
Slope & Aspect raster data layers.
The insolation data in the web map can be used to conduct feasibility analysis for solar photo-voltaic or hot-water potential. It could also be used as a tool for assessing the growing potential of a site.
The solar insolation values presented in the BC Solar Map is empirical.
It was calculated using the American Society of Heating, Refrigeration,
and Air-Conditioning Engineers (ASHRAE) building heat gain calculations.
As such the following assumptions and limitations should be kept in mind.
