Solar panels in Gatineau, QC

Be careful in Gatineau. At a 33.3-year payback, solar here is a long-horizon decision, mostly because electricity is relatively cheap (7.9¢/kWh). It can still make sense if rates rise or you have local incentives — but check the numbers hard before signing.

Check your specific roof in Gatineau → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.

What a typical Gatineau solar system costs

A 25-panel system (10 kW) is about right for an average Gatineau home using 10,800 kWh a year. It would produce roughly 10,974 kWh annually and offset 100% of that usage.

Notice that payback barely improves as systems get bigger, and eventually gets worse. That's because you can only save money on electricity you were going to buy anyway. Once a system covers your usage, extra panels mostly generate exports at a much lower rate.

Why Gatineau gets 1,291 sun hours

That figure comes from Google's analysis of real rooftops across Gatineau — it already accounts for shading from trees, chimneys and neighbouring buildings, which is why it's lower than the raw "hours of daylight" figures you'll see elsewhere. An unusually open, unshaded roof in Gatineau reaches about 1,421 hours, roughly 10% better than typical.
