The most common Ontario solar power bank mistake is buying a 3,024Wh unit based on a YouTube review filmed in Arizona. The buyer stores it in an unheated garage.

The most expensive Ontario off grid insulation mistake is building a cabin with R-12 walls and then trying to heat it with a 1,500W electric heater, because a 1,500W heater running 16 hours a day draws 24,000Wh daily, and sustaining that load through a 4-day January gray streak requires approximately 96,000Wh of battery storage, which
