Methodology: How We Ranked the Best Solar Companies in Alhambra

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


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 Alhambra

For many people considering switching to solar, the decision of which solar installer to hire depends on pricing.The overall price and potential savings vary depending on a few key factors such as:

  • System size and type: Some models are more costly than others, so the one you choose can raise or lower your initial investment. Plus, the more solar panels you need, the more it'll cost.
  • Your location: This influences how much sunlight your roof receives, which helps determine how many panels you need.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your total installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Not including incentives, you can save an average of $28,000 over 20 years with your solar panels, too.
  • Your power bills: This will dictate your savings. In Alhambra, the average resident can save about $1,200 a year on their electricity bills.

There are several great benefits of solar despite the initial cost of installation. It can help the planet and your bank account. Additionally, it can increase the value of your home, leading to even more benefits if you decide to sell your home later.

EcoWatch's Alhambra, CA Solar Company Rankings FAQs

What is the most reputable solar installer in Alhambra?

In Alhambra, SunPower by Sun Solar-OC is the best local solar company. Our team of experts rates it 3.00 stars, so it's a good choice if you're looking to add solar panels to your home.

What is the negative environmental impact of making solar panels?

Solar panels can be bad for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to dispose of safely once they’ve reached the end of their lifespan. Making solar panels uses 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?

The average payback period for solar panel installation is about 8.4 years, but the exact period depends on local electricity costs, incentives and net metering programs.

How often do solar panels have to be replaced?

Though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is how much energy they produce will have decreased significantly after that point. You can decide to replace them once you've had them for that long or you can keep using them at a lower efficiency after that time.

Our goal is to reach as many people as we can with sensible solutions like solar energy. Our team of full-time local researchers collects solar price and installation data for every city in America then compiles it to create these digestible city guides.
