Methodology: How We Ranked the Best Solar Companies in Riverwoods
EcoWatch's solar experts analyzed each solar company in Riverwoods 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 Riverwoods
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 Riverwoods
Solar panels run off a free energy source — the sun — but before you can take advantage of this you first need to pay to set up your panels.Some significant things that determine the cost and possible savings include:
- Your income and budget: This shapes what kind of solar panels you can afford.
- Energy consumption: Solar may be a high-cost investment for families that don’t need a good amount of energy a month.
- The amount of sunlight your roof gets: If your rooftop gets limited direct sunlight, your solar panel system won’t be able to generate as much energy, which will give you lower savings on power bills than a roof that gets lots of sunlight.
- Incentives: Tax-paying citizens who buy and install a solar energy system this year can save 0 of their installation costs by taking advantage of the federal solar investment tax credit. You can also save about $14,000 on your energy bills over 20 years without incentives.
Though a solar panel system costs a sizable chunk of money upfront, it can save you much more in the long term. The question of how much, though, depends on several factors, including the size of your solar panel system and incentives.
