Methodology: How We Ranked the Best Solar Companies in Lake Forest

EcoWatch's solar experts analyzed each solar company in Lake Forest 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 Lake Forest


Below are some the criteria we examined specifically for California 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 Lake Forest

For most homeowners, whether or not to invest in solar panels comes down to the cost.The installation cost is just one important factor you should bear in mind when looking into installing solar panels. How much it'll cost and how much you can save depend on things such as:

  • The model of solar panels you’re thinking of getting: More efficient panels are more costly, so that will determine your budget for your solar project.
  • The amount of sunlight your area gets: Thanks to Lake Forest’s very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • How much power your household consumes: Homes that use a lot of power each month may need more solar panels and, consequently, be more expensive, but will also benefit more over time.
  • Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 0 of the cost of your solar system installation from your federal taxes. Plus, not including incentives, you can save about $27,000 over 20 years on your energy bills.

There are many great benefits of solar in spite of the initial cost of installation. It can help the environment and your finances. In addition, it can increase the value of your home, leading to even more benefits if you decide to sell your home later.
