How Nova Scotia compares

Nova Scotia gets more sunlight than 21% of the cities we measure, and its electricity costs more than 75% of states and provinces. Both matter, but not equally: the electricity rate usually matters more, because solar saves money by replacing power you would otherwise buy. A sunny state with cheap power often pays back slower than a cloudy state with expensive power. Why that happens →

Payback stops improving as systems grow, then gets worse. You can only save on electricity you were going to buy, so once a system covers your usage the extra panels mostly export at a lower rate.

Nova Scotia solar incentives

The 30% US federal tax credit does not apply in Canada, and the figures on this page exclude it. Canadian support comes through federal programmes such as the Canada Greener Homes Loan plus provincial and utility schemes, which vary and change — check current Nova Scotia programmes directly rather than trusting a figure on a website.

Check your net metering rules. What your utility credits you for exported power drives your return more than most rebates do, and it differs by utility.
