Methodology: How We Ranked the Best Solar Companies in Northfield

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


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 Northfield

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

  • How much sunlight your roof gets: If your roof doesn’t get a lot of direct sunlight, your solar panel 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.
  • Energy consumption: Solar may be too steep of an option for families that don’t consume a lot of energy a month.
  • Incentives: One thing that can reduce the cost of your solar project is the solar investment tax credit (ITC), which is a tax credit that’s equal to a percentage of the project cost. You can also save money on your utility bills, which can lead to an average of $14,000 of savings over 20 years.
  • Choice of solar panels: The kind of solar panels you need 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 space isn't a constraint for your project, you can go with a higher number of more affordable panels.

Although a solar panel system costs a good chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on several factors, like the angle of your roof and incentives.

EcoWatch's Northfield, IL Solar Company Rankings FAQs

What is the best solar installation company in Northfield?

The highest-rated local solar company in Northfield is SunPower by Sun N Us, with a rating of 3.00 stars.

What is the negative environmental impact of solar panels?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals when they’re made. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Solar panel manufacturing uses a lot of energy as well. The energy payback period is about 1 to 4 years.

Is it worth installing solar panels on my home?

Solar panels require a significant upfront investment that costs over ten thousand dollars, but whether or not solar panels are worth it depends on a variety of factors like local electricity rates and the amount of direct sunlight your roof gets.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more expensive. Polycrystalline panels are less expensive but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other types can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, the layout of your roof and how much efficiency you're looking for.
