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. My gas bill is zero, my power bill is negative today and it’s still technically winter …
How many solar panels do you have to generate this?
My roof sucks for solar so we only have a 5kW system. We’re in an infill duplex on the shady side.
Appreciate the post. More data the better. I wish I could afford getting solar.
If you live in Calgary, the city has a fantastic funding program. The city puts up the money and then you repay it as a top up on your property taxes with a minimal interest rate.
The payback period of solar is generally shorter than the payback period of the loan from the city so it’s likely you would see your monthly cash flow improve right off the hop.
There are other communities in Alberta offering similar programs. I’m a giant nerd about this stuff so feel free to DM me.
Wow really, damn I didn’t know about that program, I’ll look it up and appreciate the offer. Gotta get a new roof first. Don’t have space in the yard.

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.
