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 Wisconsin 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

Even though solar panels can save you a decent chunk of change on energy bills over time, it's necessary to consider the upfront costs. Some important things that impact the cost and possible savings include:

  • System size and type: Some models are more expensive than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Electricity consumption: The average home in Ottawa uses a decent amount of, and therefore may save on their energy bills.
  • How much energy costs for you: The typical household in Ottawa shells out around $1,600 a year on home energy use alone, so you could be looking at that much in savings.
  • Incentives: The federal solar investment tax credit currently lets you lower your taxes by 30% of the project cost. Your state and city may also have incentives and rebates that you can take advantage of. Additionally, you can save about $21,000 over 20 years on your utility bills, without incentives.

Due to solar panels now being cheaper than ever as well as several solar incentives, they are a sound investment for the majority of homeowners.

Solar Incentives in Ottawa

In our article on solar incentives, you can find out about the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Ottawa

There are many reasons to make the switch to solar power, like saving on utility bills and helping to lower your carbon footprint. Something many might be thinking about is how much can they really help save the environment by going solar anyway? Everyone can help the planet by switching to solar energy, but homes that consume lots of energy will have an even greater impact. In Ottawa, the average person can lower their carbon footprint by 90 pounds a year once they go solar. As you can see, trading traditional energy for solar has so many other rewards beyond saving money. One of the major ones is that you can help save the planet too.
