Methodology: How We Ranked the Best Solar Companies in Helvetia
EcoWatch's solar experts analyzed each solar company in Helvetia 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 Helvetia
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 Helvetia
While solar panels can save you a decent chunk of change on energy over time, it’s necessary to know the startup costs.There are quite a few factors you should take into consideration when trying to determine costs and your potential savings, such as:
- Incentives: Something that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save money on your power bills, which can result in an average of $16,000 of savings over 20 years.
- The amount of sunlight your roof gets: Thanks to Helvetia’s high amount of average daily sunlight, you should be able to save a decent amount on your energy bills.
- The type of solar panel system you have the money for: This hinges on how much you’re willing to spend upfront.
- How much electricity your household consumes: Households that use lots of power each month may require more solar panels and, as a result, be more expensive, but will also benefit more over time.
So is installing solar panels worth it? Whether you want to reduce your electricity costs, carbon emissions or both, solar panels are a worthwhile investment for many Helvetia homeowners.
