Solar panels in Kelowna, BC
Roofs in Kelowna get about 1,350 hours of usable sunlight a year — less than 89% of the cities we've measured. Here's what that means in cost, savings and payback, using real rooftop data rather than a national average.
Check your specific roof in Kelowna → City averages are a starting point; your own roof's size, pitch and shading change the answer a lot.
What a typical Kelowna solar system costs
A 24-panel system (9.6 kW) is about right for an average Kelowna home using 10,800 kWh a year. It would produce roughly 11,016 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,672 | CA$9,120 | CA$455 | 20 yrs |
| 12 panels | 4.8 kW | 5,508 | CA$13,680 | CA$683 | 20 yrs |
| 16 panels | 6.4 kW | 7,344 | CA$18,240 | CA$911 | 20 yrs |
| 20 panels | 8 kW | 9,180 | CA$22,800 | CA$1,138 | 20 yrs |
| 26 panels | 10.4 kW | 11,934 | CA$29,640 | CA$1,374 | 21.6 yrs |
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 Kelowna gets 1,350 sun hours
That figure comes from Google's analysis of real rooftops across Kelowna — 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 Kelowna reaches about 1,387 hours, roughly 3% better than typical.
