Solar panels in Halifax, NS

What a typical Halifax solar system costs
A 24-panel system (9.6 kW) is about right for an average Halifax home using 10,800 kWh a year. It would produce roughly 10,926 kWh annually and offset 100% of that usage.
| System | Size | kWh/yr | Net cost | Saves/yr | Payback |
|---|---|---|---|---|---|
| 8 panels | 3.2 kW | 3,642 | CA$9,120 | CA$667 | 13.7 yrs |
| 12 panels | 4.8 kW | 5,463 | CA$13,680 | CA$1,000 | 13.7 yrs |
| 16 panels | 6.4 kW | 7,284 | CA$18,240 | CA$1,333 | 13.7 yrs |
| 20 panels | 8 kW | 9,105 | CA$22,800 | CA$1,666 | 13.7 yrs |
| 26 panels | 10.4 kW | 11,837 | CA$29,640 | CA$2,024 | 14.6 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 Halifax gets 1,339 sun hours
That figure comes from Google's analysis of real rooftops across Halifax — 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 Halifax reaches about 1,465 hours, roughly 9% better than typical.
