Methodology: How We Ranked the Best Solar Companies in Merrillville

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


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.

Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to set up your panels.Some key factors that influence how much it will cost to install a solar panel system on your home and how much money you could save over time include:

  • System size and type: Some models are more costly than others, so the one you get can raise or lower your initial investment. Plus, the more solar panels you need to buy, the more it'll cost.
  • How much electricity your home consumes: Homes that consume a lot of power each month may require more solar panels and, consequently, be more expensive, but will also benefit more over time.
  • Incentives: The federal solar investment tax credit currently allows you to decrease your taxes by 0 of the project cost. Your state and even local utility companies may also have incentives and rebates that you can take advantage of. Plus, you can save about $20,000 over 20 years on your utility bills, before factoring in incentives.
  • The amount of sunlight your house gets: Because of Merrillville’s high amount of average daily sunlight, you should be able to save a decent amount on your electric bills.

EcoWatch's Merrillville, IN Solar Company Rankings FAQs

Which solar power company is the best in Merrillville?

In Merrillville, SunPower by Sun N Us is the top local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're planning on installing solar panels on your home.

What are the pros and cons of solar power?

The advantages of solar power are that it can reduce or, in some cases, totally erase your electricity bills, raise your home’s value and lower your carbon footprint. The biggest disadvantages are that solar panels can be expensive to install, you may not save a lot if you don’t use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take for solar to pay for itself?

Solar panels usually pay for themselves in about 13.8 years, but your solar payback period will vary based on your utility costs. The higher your typical electricity bill, the faster your solar panel system will pay for itself.

How long do solar panels last?

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 the amount of energy they produce will have decreased by about 0.8% each year since installing them. You can choose to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
