Methodology: How We Ranked the Best Solar Companies in Oakville

EcoWatch's solar experts analyzed each solar company in Oakville 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 Oakville


Below are some the criteria we examined specifically for Missouri 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 Oakville

Solar panels are powered by a free energy source — the sun — but to take advantage of this you will need to pay to install your panels.Some key things that influence how much it will cost and how much you could save include:

  • Average daily sunlight: Since Oakville gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which influences how much you can save on your energy bills.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your total installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $17,000 over 20 years with your solar panels, too.
  • average energy usage: The more energy your home uses on average and the higher your current electricity bills are, the more benefits you’ll see from switching to solar.
  • Your current power bills: Solar panels can significantly lower, or entirely get rid of, your utility bills. In Oakville, you can save an average of $1,291 a month.

There are many good benefits of solar despite the upfront cost of installation. It can help the planet and your wallet. Plus, it can boost the value of your home, resulting in even more benefits if you decide to sell your home later.

Environmental Impact of Switching to Solar in Oakville

Switching to solar energy can have a positive effect on the environment.But how much can using solar energy instead of traditional energy actually affect the environment? Using renewable energy for electricity instead of burning fossil fuels is an impactful way to lower carbon dioxide emissions if you're conscious of Oakville's large level of greenhouse gas emissions.Though solar panel production releases carbon dioxide emissions, the panels make up for it by considerably reducing the amount of CO2 you would have released if you still used nonrenewable energy. In Oakville, you can reduce your carbon footprint by 100 pounds a year with solar panels. As you can see, trading traditional energy for solar has so many other benefits beyond saving money. One of the major ones is that you can help save the environment too.

What is the efficiency of solar panels?
