Before diving into savings, it’s important to understand what you’re currently paying. The average Ontario household consumes about 750 to 900 kWh of electricity per month. With hydro rates climbing over the years, many homeowners are paying $1,500 to $2,000 or more annually on electricity bills — and those numbers are projected to rise. Choosing to stick with traditional electricity means remaining at the mercy of these fluctuating rates. But switching to solar panels in Ontario gives you the opportunity to lock in your energy costs for decades.
