I am on the upper French river. I installed a solar sydtem 2 years ago. I went with a 24 volt system, with a 3000 watt solar bank mounted on the ground and with the advise from a couple friends, I installed it myself. I have 6 - 100AH lithium batteries that weigh 60 lbs each, which makes it easy to bring home when I close up for the year. With the price of these batteries, there's no way I'll take the chance and leave them at the cottage all winter. We now have 2 fridges plus a bar fridge for dew worms. There is plenty of power for any power tool, a 3/4hp jet pump, microwave, toaster, air fryer and charging the boat batteries including a 36 volt trolling motor. I also went to a tankless water heater, so now my propane use is now 40% what it used to be. The solar system is a big investment, but it really is a game changer. Now it's like walking into your house. The fridges are full and running, no need to lug gas cans for the generator, it's a real game changer.
I'm no expert by any means but I bought my whole system from "The Solar Shopping Mall" in Mississauga. This guy knows his stuff and was real patient with me teaching me how this system works and how to set it up. There was a couple times I called him and he would talk me through something I didn't understand.
