Be careful in Barrie. At a 15.9-year payback, solar here is a long-horizon decision, mostly because electricity is relatively cheap (15.2¢/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 Barrie → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.

What a typical Barrie solar system costs

A 23-panel system (9.2 kW) is about right for an average Barrie home using 10,800 kWh a year. It would produce roughly 10,956 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 Barrie gets 1,401 sun hours

That figure comes from Google's analysis of real rooftops across Barrie — 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 Barrie reaches about 1,484 hours, roughly 6% better than typical.
