The Cost and Benefits of Solar in Ontario

Solar panels run off a free energy source — the sun — but before you can take advantage of this you must first pay to set up your system. A few important factors that dictate how much it will cost to install a solar panel system on your home and how much money you could save over time include:

  • The cost of electricity in your area: If your local energy rates are high, there's a good chance you'll see a higher return on your investment in a solar system. In Ontario, you can save an average of $63 a month on your electricity bills.
  • System size and type: Some models are more costly than others, so the one you want can raise or lower your upfront cost. Plus, the more solar panels you need to buy, the more it'll cost.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 30% of the project cost. Your state and even local utility companies may also have incentives and rebates that you can use. Additionally, you can save about $25,000 over 20 years on your utility bills, without incentives.
  • The amount of sunlight your roof gets: This, plus your roof configuration, affects affect how much power your solar panels can produce.

Solar is a valuable investment for most homeowners. You can make your own electricity instead of paying for it from a utility company and make use of solar incentives and rebates, all while helping the planet.
