Methodology: How We Ranked the Best Solar Companies in Ottawa
EcoWatch's solar experts analyzed each solar company in Ottawa 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 Ottawa
Below are some the criteria we examined specifically for Illinois 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 Ottawa
We understand that for lots of homeowners, the decision to invest in solar highly depends on installation costs. The cost and possible savings vary depending on a few important factors such as:
- The type of solar panel system you have the money for: This depends on how much you're willing to invest upfront.
- Incentives: Those who purchase and install a solar energy system this year can save 30% of their installation costs by using the federal solar investment tax credit. You can also save about $14,000 on your utility bills over 20 years without incentives.
- Your energy bills: This will impact how much you can save. In Ottawa, the average resident can save about $940 a year on their electricity bills.
- average energy usage: The more power your home uses on average and the steeper your current power bills are, the more money you could save by going solar.
There are several great benefits of solar despite the upfront cost of installation. It can help the environment and your wallet. Additionally, it can increase the value of your home, leading to even more benefits if you choose to sell your home later.

EcoWatch's Ottawa, IL Solar Company Rankings FAQs
Which solar power company is the best near me?
In Ottawa, CF Solar Power is the top local solar company. Our team of experts rates it 3.00 stars, so it's a good choice if you're looking to add solar panels to your house.
Are solar panels really environmentally friendly?
Producing solar panels requires chemicals and produces toxic waste that can be dangerous for the environment, which is the main downside of solar panels.
Are solar panels worth it?
Solar panels can be a beneficial investment for a majority of homeowners, but admittedly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your energy bills are already pretty low, solar panels might not be for you.
When is the best time of year to install solar panels?
Despite summer being the most common time people install solar panels, the ideal time is actually winter. You can save money since there's not as much demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.
Our goal is to reach as many people as we can with sensible solutions like solar energy.
