Methodology: How We Ranked the Best Solar Companies in South Pasadena

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

Although solar panels can save you money on electricity bills over time, it's necessary to know the upfront costs. The cost of solar and the savings it generates vary depending on a few key factors such as:

  • Your income and budget: This guides what type of solar panels you can buy.
  • How much you spend on energy: The typical household in South Pasadena shells out around $890 a year on energy use alone, so you could gain that much in savings.
  • Incentives: The federal solar investment tax credit currently allows you to reduce your taxes by 30% of the project cost. Your state and even local utility companies may also have various incentives that you can take advantage of. In addition, you can save about $30,000 over 20 years on your utility bills, not including incentives.
  • How much electricity your home consumes: Households that use lots of energy each month may call for more solar panels and, therefore, more upfront cost, but will also benefit more over time.

Solar is a worthwhile investment for most homeowners. You can generate your own power instead of paying for it from a utility company and take advantage of solar tax credits and rebates, all while helping the environment.

Solar Incentives in South Pasadena

Switching to solar power has many considerable benefits. Not only can it help protect the environment, but you can also save some money on your installation with various government incentives. There are a lot of federal, state and local rebates and tax credits that can earn you a decent amount of money in return after buying solar panels. For detailed information about local incentives, check out our article on solar incentives.

Environmental Impact of Switching to Solar in South Pasadena

There are a few important reasons why homeowners want to invest in solar energy: for the financial and environmental benefits. But how much can using solar energy instead of traditional energy actually help the environment? In South Pasadena, where the energy generation could be cleaner, going solar can have a huge effect on the Earth since solar power is an abundant source of clean energy. Because solar panels don't release CO2 emissions into the atmosphere when producing electricity, they're a good swap for traditional energy sources. In fact, you could lower your carbon dioxide emissions by about 50 pounds each year. If you want to do your part for the environment, you'll most likely find that there are many good things about adopting solar energy other than just saving money on bills. You can also help preserve the environment, which some would argue is worth more.

EcoWatch's South Pasadena, CA Solar Company Rankings FAQs

Which solar installation company is the best near me?

In South Pasadena, SolarGnosis is the top local solar company. Our team of experts rates it 3.00 stars, so it's a great choice if you're looking to add solar panels to your roof.

Are solar panels actually good for the environment?

Solar panels can be harmful for the environment when manufacturers use toxic chemicals when they're made. Chemicals can make solar panels difficult to recycle safely once they've reached the end of their lifespan. Making solar panels needs a lot of energy as well. The energy payback period is about 1 to 4 years.

How long does it take for solar to pay for itself?

Solar panels generally pay for themselves in about 6.1 years, but your solar payback period will vary depending on your utility costs. The higher your typical power bill, the quicker your solar panel system will pay for itself.

When should I put up solar panels?

Although summer is the most common time people install solar panels, the ideal time is actually winter. You can save money since there's decreased demand during the winter months, and it lets you be up and running with solar for the more expensive power bills you may get during the summer.

Our goal is to reach as many people as we can with sensible solutions like solar energy.
