Methodology: How We Ranked the Best Solar Companies in Wonder Lake
EcoWatch's solar experts analyzed each solar company in Wonder Lake 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 Wonder Lake
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 Wonder Lake
We understand that for many homeowners, the choice to invest in solar highly depends on installation costs.Some key things that affect the cost and possible savings include:
- System size and type: Some models are more pricy than others, so the one you want to get can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
- Incentives: The federal solar investment tax credit, which can save you some money, lets you deduct 0 of the cost of your solar system installation from your federal taxes. Additionally, not including incentives, you can save about $13,000 over 20 years on your energy bills.
- How much you spend on energy: The typical household in Wonder Lake shells out around $1,200 a year on home energy use alone, so you could end up with that much in savings.
- How much power your household consumes: Households that use a lot of energy each month may need more solar panels and, consequently, more upfront cost, but will also save more on their energy bills over time.
Because of solar panels decreasing in cost as well as various solar incentives, they are a cost-effective investment for most homeowners.
