Methodology: How We Ranked the Best Solar Companies in Fremont
EcoWatch's solar experts analyzed each solar company in Fremont 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 Fremont
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 Fremont
The cost of putting up solar panels has dropped significantly in the past several years, but it’s still a significant investment for most homeowners.The cost and possible savings vary depending on a few key factors such as:
- Your income and budget: This guides what type of solar panels you can purchase.
- The amount of sunlight your roof gets: If your roof gets limited direct sunlight, your solar system won’t be able to make as much energy, which will leave you with lower savings on energy bills than a roof that gets a lot of sunlight.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $14,000 over 20 years with your system, too.
- How much power your household needs: If your household uses a lot of energy, you'll benefit more from going solar.
There are lots of wonderful benefits of solar despite the upfront cost of installation. It can help the planet and your wallet. Additionally, it can raise the value of your home, giving you even more benefits if you choose to sell your home later.

One of the best reasons to adopt solar power is to minimize your reliance on traditional energy sources like burning fossil fuels, which are destructive for the environment.But – how much exactly can you help the environment by using solar power? Something that can severely shape your carbon footprint is how long your commute is and how much you drive overall. If you switch to solar power and have an electric car, you can greatly lower your carbon dioxide emissions by charging your car at home.In fact, if you make the switch to solar power, you could look forward to lowering your carbon dioxide emissions by about 90 pounds each year.
