Methodology: How We Ranked the Best Solar Companies in Glendora

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


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 Glendora

The cost of installing a solar panel system has dropped immensely over the past several years, but it’s still a substantial investment for most homeowners.There are several factors you should consider when trying to determine costs and your potential savings, such as:

  • Incentives: The federal solar investment tax credit currently lets you reduce your taxes by 0 of the project cost. Your state and even local utility companies may also have incentives and rebates that you can benefit from. Plus, you can save about $25,000 over 20 years on your utility bills, not including incentives.
  • System size and type: Some models are more pricy than others, so the one you choose can raise or lower your upfront cost. Plus, the more solar panels you need to get, the more it'll cost.
  • Where your home is: This influences how much sunlight your roof receives, which helps determine how many panels you need.
  • How much energy costs for you: The average household in Glendora pays around $1,200 a year on power alone, so you could gain that much in savings.

There are several wonderful benefits of solar despite the initial cost of installation. It can help the planet and your bank account. Additionally, it can raise the value of your home, resulting in even more benefits if you choose to sell your home later.

Solar Incentives in Glendora

To increase the number of homes and businesses that use solar power, federal and local governments – and even some utility companies – offer incentives to help make solar power more financially viable and accessible.Everyone can take advantage of the federal Solar Investment Tax Credit (ITC), which lets you claim 0 of how much you paid for your solar installation when you file taxes, reducing the amount of taxes you owe that year. In addition, there may be some local incentives you can benefit from too. For more information about incentives for homeowners in Glendora, check out our article on solar incentives.

Environmental Impact of Switching to Solar in Glendora

There are many reasons to make the switch to solar energy, like saving money on electricity bills and helping to lower your carbon footprint.A question many homeowners might be asking themselves is how much can they really help save the environment by switching to solar power anyway? One thing to consider is your overall carbon footprint. For example, if you have a long commute time and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.Although solar panel production emits carbon dioxide, the panels make up for it by greatly reducing the amount of CO2 you would have produced if you still used traditional energy. In Glendora, you can reduce your carbon footprint by 50 pounds a year with solar panels. If you care about the environment, you’ll most likely recognize that there are many advantages to adopting solar energy other than just saving money on electricity. You can also help protect the environment, which some would argue is worth more.
