We are so, so absurdly lucky in Alberta - we get SO MUCH SUN. It's mid-March and I generated double the power my heat-pump equipped home used. Even after I replace the power I pulled from my EV commuting to work, that's still 7kWh more power coming off my roof today than I used.

There's the program website. You might be able to roll the roof upgrade into the funding - max is $50k. Some friends did all of their windows and some other stuff. You get a max of 20 years to repay and most energy retrofits pay for themselves in just a few years.
