Rooftop Solar Potential — Canada

Measure the roof section that faces the sun; get the system it fits and the CAD value it produces.

Fitting assumes ~5.2 m² of roof per installed kW with modern 425 W panels, less 10% for setbacks, chimneys, and shading at the edges. Orientation factors are typical Canadian derates. Snow losses in Canada add roughly 2-5% annual reduction on low-slope roofs.
