Methodology: How We Ranked the Best Solar Companies in St. John

EcoWatch's solar experts analyzed each solar company in St. John 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 St. John


Below are some the criteria we examined specifically for Indiana 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 St. John

For the majority of homeowners, whether or not to invest in solar energy boils down to the cost.The installation cost is just one important factor you should bear in mind when looking into getting solar panels. How much it'll cost and how much you can save depend on things such as:

  • The kind of solar panels you’re thinking of getting: More high-tech panels are more highly priced, so that will influence your budget for your solar project.
  • How much sunlight your roof gets: If your roof doesn’t get a lot of direct sunlight, your solar system won’t be able to generate as much energy, which will leave you with lower savings on electricity bills than a house with a roof that gets a lot of sunlight.
  • How much power your household consumes: Homes that consume plenty of electricity each month may call for more solar panels and, consequently, be more costly, but will also save more on their energy bills over time.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you receive a tax credit curretnly worth 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $20,000 over the first 20 years with your solar system, too.

Solar is a fruitful investment for most homeowners. You can generate your own power instead of paying for it from the grid and take advantage of solar incentives and rebates, all while helping preserve the planet.

Environmental Impact of Switching to Solar in St. John

Installing solar panels can have a meaningful effect on the environment.But you may be curious – how much exactly can you help the environment by using solar power? How much energy you use is an important factor to keep in mind. The more electricity your home uses, the larger your impact when you make the switch to solar power.Because solar panels don’t release carbon dioxide emissions into the atmosphere when creating electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could expect to reduce your carbon dioxide emissions by about 90 pounds each year. Since solar energy is renewable and produces electricity without CO2 emissions, adding solar panels to your home is one easy step you can take to help protect the environment.

EcoWatch's St. John, IN Solar Company Rankings FAQs

Which solar installation company is the best near me?

In St. John, WindSoleil Solar and Wind Energy Services is the top local solar company. Our team of experts rates it 5.00 stars, so it's a good choice if you're planning on installing solar panels on your home.

What are the major pros and cons of switching to solar?

A few of the biggest pros are that it reduces your power bills, it’s eco-friendly, and it can give you a decent return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, the installation cost is pricey and solar panels aren’t always aesthetically pleasing.

Is it worth putting solar panels on my home?

Solar panels can be a good investment for most homeowners, but honestly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already fairly low, solar panels might not be for you.

How often do solar panels need to be replaced?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they stop working completely. What this means is how much energy they produce will have decreased by about 0.8% each year since installing them. You can opt to replace them after having them for that long or you can keep using them at a lower efficiency after that time.
