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

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


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.

EcoWatch's St. Joseph, IL Solar Company Rankings FAQs

Which solar company is the best near me?

The best local solar company in St. Joseph is StraightUp Solar of Bloomington, with a rating of 4.90 stars.

What are the pros and cons of solar power?

A few of the biggest pros are that it reduces your power bills, it’s good for the environment, and it gives you a significant return on your investment (ROI). The most notable cons are that solar panels don’t produce electricity at night, the startup costs are high and solar panels aren’t always aesthetically pleasing.

Are solar panels worth it?

Solar panels can be a good investment for a majority of homeowners, but truthfully, 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 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 should be disposed of. What this means is their energy production will have decreased significantly after that point. You can decide to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.
