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

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 Chilliwack gets 1,143 sun hours

That figure comes from Google's analysis of real rooftops across Chilliwack — 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 Chilliwack reaches about 1,260 hours, roughly 10% better than typical.
