Methodology: How We Ranked the Best Solar Companies in Rosemead

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


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 Rosemead

For many people, the decision of which solar installer to hire depends on total costs.There are a few factors you should consider when determining how much it will cost and how much you can save, such as:

  • Incentives: One thing that can make your solar project cost less is the solar investment tax credit (ITC), which is a tax credit that lets you deduct from your taxes a percentage of the project cost. You can also save on your power bills, which can generate an average of $25,000 of savings over 20 years.
  • How much sunlight your roof gets: If your roof doesn’t get a lot of direct sunlight, your solar panels won’t be able to generate as much energy, which will leave you with lower savings on electricity bills than a house with a roof that gets a lot of sunlight.
  • Your income and budget: This guides what model of solar panels you can purchase.
  • How much energy costs for you: If your local energy rates are high, there's a good chance you'll get a higher return on your investment in a solar panel system. In Rosemead, you can save an average of $1,185 a month on your electricity bills.

There are lots of good benefits of solar despite the upfront cost of installation. It can help the Earth and your finances. In addition, it can increase the value of your home, giving you even more benefits if you choose to sell your home later.

What are the biggest pros and cons of going solar?

A few of the biggest pros are that it decreases your power bills, it’s a sustainable source of energy, and it can provide a significant return on your investment (ROI). The most notable cons are that solar panels don’t work as well when there’s limited direct sunlight, there is a high upfront cost and solar panels can look clunky on your roof.

Is it worth installing solar panels on my house?

Solar panels can be a great investment for most homeowners, but honestly, they might not be worth it for everyone. If your home doesn't get enough sunlight or your electricity bills are already fairly low, solar panels might not be for you.

What is the best kind of solar panel?

The different types of solar panels are monocrystalline, polycrystalline and thin-film. Monocrystalline panels are more efficient but also more costly. Polycrystalline panels are cheaper but also less efficient than monocrystalline. Thin-film solar panels are flexible, so they can be used where the other kinds can’t, like on curved surfaces or cars, but they are also less efficient. The best one for you depends on your budget, roof configuration and how much efficiency you're looking for.
