I bought 30 375w Canadian Solar panels 2 years ago and paid $0.41/watt (~$4536 for the whole package)
My mounting equipment actually cost more than the panels (~$4600). And the permitting process cost nearly as much as the panels (permit cost + architectural drawing + structural engineer stamp + electrician stamp).
It's crazy how cheap solar panels themselves are getting. They're going to win on the energy front - period. Especially now that battery tech actually seems to be moving again. I vividly remember one of my robotics professors in undergrad ranting about how frustrated he was with battery tech in ~2007, but LFP and sodium batteries are both pretty huge steps forward.

How much does power and grid delivery cost in Canada to make this economical? You're into this for $15,000 what is your payback period? Are there other ameliorating criteria for success?
Another data point: my entire system in Switzerland cost me 1.3CHF/Watt including a 20kWh battery and 5000 CHF of scaffolding costs (needed because of our local OSHA equivalent laws when installing panels on a tilted roof).
It has become ridiculously cheap indeed.
