The Cost and Benefits of Solar in Ontario

For many homeowners, whether or not to invest in solar panels comes down to the cost. A few important factors that affect the cost of installing solar panels on your home and how much money you could save over time include:

  • Incentives: Something that can save you money on your solar project is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your power bills, which can result in an average of $25,000 of savings over 20 years.
  • How much you spend on energy: The typical household in Ontario pays around $750 a year on home energy use alone, so you could gain that much in savings.
  • The model of solar panels you're planning on getting: More high-tech panels are more expensive, so that will influence your budget for your solar project.
  • Average daily sunlight: Since Ontario gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which impacts how much your solar panels can save you on your electricity bills.

There are lots of wonderful benefits of solar in spite of the initial cost of installation. It can help the Earth and your finances. Plus, it can increase the value of your home, leading to even more benefits if you choose to sell your home later.

Solar Incentives in Ontario

Adopting solar power has plenty of wonderful benefits. Not only can it help protect the planet, but you can also save a good amount of money on your installation with various government incentives. You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also possibly use the ITC with other state and city rebates and benefits. Take a look at our article on solar incentives to see what incentives you can take advantage of.

Environmental Impact of Switching to Solar in Ontario

If you're considering adding solar panels to your home, one of the major reasons why may be to reduce your carbon dioxide emissions. But how much can switching to solar actually affect the environment? The average person has a sizable carbon footprint. Between their car, which produces over 10,000 pounds of carbon dioxide emissions every year, and powering their home, it can be overwhelming to figure out what to do. Installing solar panels is a practical thing you can do to help. Because solar panels don't release carbon dioxide emissions into the atmosphere when generating electricity, they're a good swap for traditional energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. Since solar energy is renewable and produces electricity without releasing carbon emissions, making the switch to solar power is one easy step you can take to help the planet.

EcoWatch's Ontario, CA Solar Company Rankings FAQs

What is the best solar installer in Ontario?

In Ontario, Renewable USA is the best local solar company. Our team of experts rates it 5.00 stars, so it's a solid choice if you're looking to add solar panels to your home.

Are solar panels really good for the environment?

Making solar panels requires chemicals and produces toxic waste that can be dangerous for the environment, which is the main downside of solar panels.

How long does it take for solar to pay for itself?

Solar panels typically pay for themselves in about 7.3 years, but your solar payback period will depend on your utility costs. The higher your typical power bill, the faster your solar panel system will recoup your installation costs.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels cost less but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can't, such as on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof layout and desired energy output.
