Methodology: How We Ranked the Best Solar Companies in Berkeley

EcoWatch's solar experts analyzed each solar company in Berkeley 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 Berkeley


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 Berkeley

We know that for lots of homeowners, the choice to invest in solar comes down to installation costs.The installation cost is just one important factor you should take into account when looking into getting solar panels. How much it'll cost and how much you can save depend on things including:

  • Your home's orientation toward the sun: This, and your roof configuration, affects affect how much electricity your solar panels can generate.
  • Choice of solar panels: The type of solar panels you choose 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.
  • Incentives: Tax-paying citizens who buy and install a solar system this year can save 0 of their overall solar costs by using the federal solar investment tax credit. You can also save about $13,000 on your utility bills over 20 years excluding incentives.
  • Typical energy usage: The more electricity your household uses on average and the greater your current power bills are, the more benefits you’ll see from going solar.

Though a solar panel system costs a decent chunk of money upfront, it can save you a considerable amount over time. The question of how much, though, depends on several factors, such as the size of your house and incentives.
