Methodology: How We Ranked the Best Solar Companies in Wood River
EcoWatch's solar experts analyzed each solar company in Wood River 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 Wood River
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 kind of solar panel system you can buy: This depends on how much you’re willing to invest upfront.
- 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.

EcoWatch's Wood River, IL Solar Company Rankings FAQs
Which solar power company is the best in Wood River?
In Wood River, 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 on installing solar panels on your house.
What are a few of the biggest advantages and disadvantages of adopting solar power?
A few of the biggest pros are that it lowers your electricity bills, it’s environmentally friendly, and it can give you a decent return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, they cost a lot upfront and solar panels can be an eyesore.
Is it worth putting solar panels on my roof?
Solar panels can be a beneficial investment for most homeowners, but frankly, they might not be worth it for everyone. If your home doesn't get a lot of direct sunlight or your power bills are already reasonably low, solar panels might not be for you.
How long do solar panels last?
Even 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 by about 0.8% each year since installing them. You can opt to replace them once you've had them for that long or you can keep using 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.
