Methodology: How We Ranked the Best Solar Companies in Brighton
EcoWatch's solar experts analyzed each solar company in Brighton 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 Brighton
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 Brighton
For many people, the decision of which solar company to hire depends on pricing.Some significant things that determine the upfront cost and potential savings over time include:
- 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 will help you save even more. Excluding incentives, you can save an average of $17,000 over the first 20 years with your system, too.
- How much power your household consumes: Households that need a lot of energy each month may require more solar panels and, consequently, be more expensive, but will also save more on their energy bills over time.
- 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 space isn't a constraint for your project, you can go with a higher number of more affordable panels.
- Average daily sunlight: Since Brighton gets a decent amount of average daily sunlight, your solar panels can generally produce enough energy to power your whole home, which impacts how much your electricity bills will be.
Although a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on several factors, including the kind of solar panels you get and your local electricity rates.

EcoWatch's Brighton, IL Solar Company Rankings FAQs
Which solar company is the best near me?
In Brighton, Astrawatt Solar is the top local solar company. Our team of experts rates it 5.00 stars, so it's a great choice if you're planning to add solar panels to your home.
What are the best and worst things about solar power?
A few of the biggest pros are that it lowers your electricity bills, it’s a sustainable source of energy, and it gives you a decent 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 can be an eyesore.
How long does it take to see a return on your investment after buying solar panels?
The average payback period for solar panel installation is about 15.1 years, but the exact period is influenced by local electricity costs, incentives and net metering programs.
How long do solar panels last?
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 significantly after that point. 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.
