Methodology: How We Ranked the Best Solar Companies in Fremont

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


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.

The Cost and Benefits of Solar in Fremont

Solar panels run off a free energy source — the sun — but before you can take advantage of this you will first need to pay to install your system. Some main factors that influence the cost of installing solar panels on your home and how much money you could save over time are:

  • Your power bills: This will influence your savings. In Fremont, the average homeowner can save about $900 a year on their electricity bills.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can take advantage of. Additionally, you can save about $14,000 over 20 years on your utility bills, before factoring in incentives.
  • Choice of solar panels: The kind of solar panels you buy will affect your total cost. High-efficiency monocrystalline panels will cost more upfront but can also save you more money over the lifetime of your system. If you don't need to maximize efficiency, you can go with a higher number of more affordable panels.
  • How much sunlight your roof gets: If your rooftop doesn't see much direct sunlight, your solar panels won't be able to produce as much energy, which will give you lower savings on electric bills than a roof that gets lots of sunlight.

Solar is a profitable investment for most homeowners. You can generate your own energy instead of paying for it from the grid and benefit from solar incentives, all while helping preserve the environment.

Solar Incentives in Fremont

If you're planning on switching to solar energy, a number of government incentives and subsidies can drastically reduce the installation costs and expedite the return on your investment. No matter what state you live in, you can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 30% of how much your solar project cost on your tax return, lowering the amount of taxes you owe that year. Plus, there may be some local incentives that stack with the ITC too. In our article on solar incentives, you can see the incentives you qualify for near you.

Environmental Impact of Switching to Solar in Fremont

Installing solar panels is a powerful way to do what you can for a greener future. But how much can using solar energy instead of traditional energy actually affect the environment? Everyone can help protect the planet by switching to solar energy, but homes that use a lot of energy will have a bigger impact. In Fremont, the average homeowner can lower their carbon footprint by 90 pounds a year after going solar. As you can see, trading traditional energy for solar has so many other perks outside of saving money. One of the primary ones is that you can help save the planet too.

EcoWatch's Fremont, IL Solar Company Rankings FAQs

Which solar power company is the best in Fremont?

The highest-rated local solar company in Fremont is ilumen Solar, with a rating of 4.01 stars.

What are the best and worst things about solar power?

The biggest advantages of solar power are that it can lower or, for some, 100% erase your electricity bills, raise your home's value and lower your carbon footprint. The biggest disadvantages are that solar panels can be pricey to install, you may not save a lot if you don't use a lot of electricity and it doesn't work for all roof types and locations.

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

Solar panels generally pay for themselves in about 13.4 years, but your solar payback period will vary based on your utility costs. The higher your typical energy bill, the faster your solar panel system will recoup your installation costs.

What are the different types of solar panels?

There are three main types of solar panels: monocrystalline, polycrystalline and thin-film. In terms of efficiency and price, monocrystalline has the highest for both, then polycrystalline, and then thin-film. The best choice for you is highly influenced by your roof layout, how much you're willing to spend and how much energy generation you want.
