Methodology: How We Ranked the Best Solar Companies in Ontario
EcoWatch's solar experts analyzed each solar company in Ontario based on criteria such as its reputation in the industry, customer reviews, services, warranty coverage and financing. Using this solar methodology, we used the data we collected to rate and rank each company and narrow down our picks for the best solar companies in Ontario
Below are some the criteria we examined specifically for California solar companies
- Brand reputation and certifications (20%): We take each company's Better Business Bureau (BBB) score into consideration, as well as how long the installer has been in business (at least 5 years is required, 10 preferred) and what type of solar certifications it holds.
- Customer reviews (20%): Trust is a top priority at EcoWatch, so we take customer experience under close consideration. We scour different review sites and customer testimonials when ranking our top solar companies, checking sites such as Trustpilot and Google Reviews. We also consider any potential complaints or lawsuits filed against these companies and award or remove points accordingly.
- Warranty (20%): A company earns a perfect score in this category if it offers 25-year warranties that cover performance, product and workmanship. The industry standard that we measure companies against is 25-year product and performance warranties, along with a 10-year workmanship warranty. We also look closely into the track record of the post-installation support each company provides in terms of honoring its contracts
- Solar services (10%): All of the companies we review install solar panels, but we award companies higher points if they offer additional services for customers, like battery installation, energy-efficiency audits, and EV chargers.
- Pricing and financing (10%): It's hard to get exact quotes for solar projects, but we use marketplace research to determine how each company prices its equipment and installation services. Additionally, companies that offer more help for panel financing — like in-house loans, leases, or PPAs — score higher than those that don't.
- Availability (10%): The bigger the service area, the higher the company will score.
- Transparency and accessibility (5%): Solar installers that offer free consultations and easy contact methods score higher in this category.
- Environmental, social and corporate governance factors (5%): A company earns a perfect score in this category if it offers public data disclosure, addresses end-of-life (EOL) products or processes, and demonstrates a commitment to uplifting the communities that it serves.
The Cost and Benefits of Solar in Ontario
We know that for many homeowners, the decision to invest in solar rests on installation costs.A few important factors that determine the cost of installing solar panels on your home and how much it could save you over time include:
- Whether or not your roof gets a lot of direct sunlight: This, and the configuration of your roof, affects affect how much electricity your solar panels can produce.
- How much you spend on energy: The average household in Ontario shells out around $1,200 a year on energy alone, so you could be looking at that much in savings.
- The model of solar panels you’re planning on getting: Higher-efficiency panels have higher prices, so that will affect your budget for your solar project.
- Incentives: The federal solar investment tax credit, which can save you some money, allows you to deduct 0 of the cost of installing your solar panel system from your federal taxes. Additionally, not including incentives, you can save about $25,000 over 20 years on your energy bills.
Solar is a fruitful investment for most homeowners. You can produce your own power instead of paying for it from a utility company and make use of solar incentives, all while helping the environment.

What is the top solar installation company in Ontario?
In Ontario, SunPower by True Power Solar is the most reputable local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're looking to add solar panels to your house.
What are some of the pros and cons of adopting solar power?
The main advantages of solar power are that it can reduce or, for some, 100% cut your electricity bills, raise the value of your home and lower your carbon footprint.

Are solar panels worth it?
Solar panels can be a great investment for many homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your energy bills are already fairly low, solar panels might not be for you.
When should I install solar panels?
You can put up solar panels whenever it's convenient for you, but consider doing so in the winter when the demand is less. With fewer homeowners going solar, you could potentially see faster installation times and more savings.
