There is a solar farm in Thunder Bay area, that's even more north than me (I'm actually not that north in the grand scheme of things when you look at the map, about equal to Germany which has lot of solar) There's one in Ramore too, which is closer to me. I don't imagine the output is that great in winter though, but it's probably super good in summer. For a few months, our days are super long. You could run A/C straight off solar and have enough capacity to keep charging batteries if the A/C is in a decent on/off cycle and not just full pin non stop. The problem is an inverter that can run an A/C is going to cost more than the A/C unit itself lol. I was looking at the 8kw Outback Radian ones they are very interesting units. If I did my whole house, I'd probably go with two of those, for redundancy. That would run the central A/C + other loads. You can set it to start to use hydro if battery voltage gets too low.
My most realistic approach if I go solar is to just do the server room, then have 2 inverters, a 2kw one for the main server rack PDU, then a 4ish kw inverter for the secondary PDU + misc outlets throughout the house. Maybe lighting circuits too. The batteries are the biggest cost, the Trojan and Surrette batteries look decent. I think the Surrette ones are actually made in Canada.
I get all gigitty looking at all this solar/power stuff, but I realisticly can't afford any of it any time soon. I do need to start saving up though. Hydro is only going to keep costing more, once I pay and install this system I will just continue to save money over my life time once it's paid off.
One big issue though is freezing rain. Get that once, and you're screwed for the rest of that year. We used to only get that maybe once a year mid/near end of winter. Now we seem to get it more often. That stuff blows. Especially when it snows right after, creates an impenetrable crust of ice/snow.
