Methodology: How We Ranked the Best Solar Companies in La Mesa

EcoWatch's solar experts analyzed each solar company in La Mesa 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 La Mesa


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 La Mesa

For most homeowners, whether or not to invest in a solar energy system boils down to the cost.There are a few factors you should take into consideration when trying to figure out how much it will cost and how much you can save, including:

  • Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • Your energy consumption: If your home needs to use a lot of energy, you'll benefit more from going solar.
  • The type of solar panels you want: Some are more highly priced, so that will affect your budget for your solar project.
  • Your power bills: This will dictate how much you can save. In La Mesa, the average resident can save about $1,700 a year on their electricity bills.

Though a solar panel system costs a decent 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, including the size of your house and your current power bills.
