In Nova Scotia, I'm very interested in your near-vertical wall mount, since the only available space I have for solar panels is on the front of my south-south-east facing barn. What azimuth(s) are your panels at, and what tilt have you used (optimized for summer, winter, year-round, or what)?
Where did you get your panels--"Canadian Solar (made in China) and are bifacial 535w" -- and what did they cost? I find that the killer for solar in Canada is the tariff of up to 165%, implemented to protect a domestic production industry which will never be competitive globally, especially since about 74% of Canadian grid production is hydro or nuclear. Locally, I can get new 400W panels for about $.75CAD a watt (about $.56USD).
In the U.S., new Adani 530W panels are available for ~$.31USD per watt: Adani 530W Panels
(As an interesting note of international arbitrage, Adani (Indian company) makes (using Chinese materials) and installs lots of panels, but does not make what it installs--90% of what it makes is sold to the U.S., avoiding tariffs on Chinese goods, and it then installs Chinese panels in India. I don't know if the U.S. Adani prices will change with the recently tariff changes.)
Battery prices in the U.S. have dropped nearly 40% in ~2 years for 100Ah 12V LiFePO4 batteries. It's possible to get 5.2kWh for a bit over $800USD--off of Amazon.
