it’s somewhat dependent on the angle and rotation of the roof relative to the sun whether solar would be effective at all. it can also take several decades to make your money back in electricity savings and there’s a lot of reasons not to commit to that.
Germany paid early and bandwagon adopters of rooftop solar almost €0.10/kWh to sell back to the grid for fifteen plus years. There is so much residential solar here it actually causes problems for grid operators.
That buyback subsidy has ended but with some of the highest electricity prices in the world and a political environment which is pushing electric heating, new solar installs are still popular.
Still plenty of sun in southern Canada to make enough power for your house. The payback isn’t based on latitude so much as it is local power cost. Granted, latitude matters eventually, like in northern Canada. But wind would be an excellent alternative in that case.
yeah don’t exactly see the roof owning class installing a lot of solar
I am lucky enough to own a roof and I do have solar.

Several decades? Is this hypothetical house inside a cave? Sounds more like anti-renewable energy propaganda.
In Australia, it takes between about 3-7 years to break even on the total cost of a system. Not close to several decades.
not propaganda, just southern canada and a decade out of date.

Still sounds questionable. E.g. the chart here for Canadian solar (https://kuby.ca/solar/solar-information/articles/the-cost-of-solar-panels) shows that you hit a relative break even point at 9-10 years on a $15k system. And a complete break even at under 20 years.
That sounds well under several decades to me.
It’s happening! Probably not in any gated communities, but a house not far from me has it.
