Methodology: How We Ranked the Best Solar Companies in Belvidere
EcoWatch's solar experts analyzed each solar company in Belvidere 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 Belvidere
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 Belvidere
Solar panels are powered by a free energy source — the sun — but to take advantage of this you first need to pay to install your panels.The overall price and potential savings vary depending on some important factors such as:
- Incentives: Tax-paying citizens who purchase and install a solar system this year can save 0 of their total solar spend by using the federal solar investment tax credit. You can also save about $14,000 on your electricity bills over 20 years excluding incentives.
- Average daily sunlight: Since Belvidere gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which impacts how much you can save on your energy bills.
- How much power your household consumes: Homes that need lots of energy each month may require more solar panels and, therefore, more upfront cost, but will also enjoy more savings over time.
- Choice of solar panels: The kind of solar panels you need will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also save you more money over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
Although a solar panel system costs a good chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on a number of factors, like the size of your house and your current power bills.
