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
We get that for lots of homeowners, the choice to invest in solar comes down to installation costs. Some significant things that affect the cost and possible savings include:
- How much energy costs for you: If your local utility rates are high, there's a good chance you'll get a higher return on your investment in a solar system. In Pasadena, you can save an average of $75 a month on your electricity bills.
- Incentives: Those who buy and install a solar energy system this year can save 30% of their solar installation costs by taking advantage of the federal solar investment tax credit. You can also save about $30,000 on your electricity bills over 20 years without incentives.
- Your city: This affects how much sunlight your roof receives, which helps determine how many panels you need.
- The type of solar panels you're thinking of getting: Some cost more, so that will influence your budget for your solar project.
So is installing solar panels worth it? Whether you want to decrease your electricity costs, carbon emissions or both, solar panels are a worthwhile investment for many Pasadena homeowners.

Because solar power is better for the environment than fossil fuels, there are quite a few government incentives available to encourage people to make the switch. You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your a solar system. You can also possibly stack the ITC with other local rebates and benefits. In our article on solar incentives, you can read about the incentives you qualify for in your area.
Environmental Impact of Switching to Solar in Pasadena
There are many reasons to switch to solar power, like saving on utility bills and helping to reduce your carbon footprint. But you may be curious — how much exactly can you help the environment by making the switch to solar? In a city like Pasadena where commute times can be very long, using solar power can help help reduce the carbon footprint of driving. Since solar panels don't release carbon dioxide emissions into the atmosphere when generating electricity, they're a good substitute for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. As you can see, using solar power has so many other rewards beyond saving money. One of the major ones is that you can help save the Earth too.
