- A large, flat, south-facing roof
PV panels should be oriented to true (not magnetic) south to max out the sun’s rays. East- and west-facing panels are possible but less effective. And the flatter the roof, the more energy the panels will absorb.
- No shade
A tree branch hanging over a panel can drastically cut power output, as can chimney shadows, neighbouring buildings or satellite dishes.
- No fear of heights
Though low-maintenance, PV panels still require cleaning twice a year to clear bird droppings, dirt and dust. Snow can also reduce the amount of energy produced.
- A sunny climate
Saskatchewan, Alberta and Manitoba get the most sunshine, so residents in these provinces get the most from solar panels.
