Methodology: How We Ranked the Best Solar Companies in Pasadena

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


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 Pasadena

For many people, the decision of which solar company to go with comes down to prices.The overall price and potential savings vary depending on a few important factors such as:

  • 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 go with a higher number of more affordable panels.
  • Your location: This influences the average daily sunlight your roof gets, which helps determine how many panels you need.
  • How much power your home consumes: Homes that use plenty of power each month may call for more solar panels and, as a result, be more expensive, but will also enjoy more savings over time.
  • Incentives: The federal solar investment tax credit currently allows you to lower your taxes by 0 of the project cost. Your state and city may also have various incentives that you can benefit from. In addition, you can save about $30,000 over 20 years on your utility bills, before factoring in incentives.

Even though a solar panel system costs a decent chunk of money upfront, it can save you thousands of dollars over the lifespan of your panels. The question of how much, though, depends on several factors, like the kind of solar panels you get and your local electricity rates.

Environmental Impact of Switching to Solar in Pasadena

If you’re considering adding solar panels to your home, one of the primary reasons why may be to lower your greenhouse gas emissions.But how much can using solar energy instead of traditional energy actually help the environment? One thing that can drastically shape your carbon footprint is how long your commute is and how much you drive overall. If you switch to solar power and drive an electric car, you can greatly cut back on your carbon dioxide emissions by charging your car at home.In fact, if you adopt solar power, you could expect to reduce your carbon dioxide emissions by about 50 pounds each year. For people who want to help the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
