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

Solar panels are powered by a free energy source — the sun — but before you can take advantage of this you will need to pay to install your panels.There are a few factors you should take into consideration when trying to determine the overall cost and how much you can save, such as:

  • Your city: This influences how much sunlight your roof gets, which helps determine how many panels you need.
  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 30% of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that will help you save even more. Not including incentives, you can save an average of $25,000 over the first 20 years with your solar system, too.
  • Your energy bills: This will affect your savings. In Glendora, the average homeowner can save about $760 a year on their electricity bills.
  • The type of solar panels you can afford: This hinges on your income and budget.

So is a solar system worth it? Whether you hope to reduce your electricity costs, carbon dioxide emissions or both, solar panels are a solid investment for many Glendora homeowners.

Solar Incentives in Glendora

One of the good things about installing a solar panel system is earning federal and potentially state incentives.In addition to the federal solar investment tax credit, there are also some local incentives, which in most cases, stack with the federal incentive, so you get to save even more. In our article on solar incentives, you can see the incentives you qualify for in your area.

Environmental Impact of Switching to Solar in Glendora

One of the most compelling reasons to use solar energy is to cut your reliance on nonrenewable energy sources like burning fossil fuels, which are harmful for the environment.But how much can using solar energy instead of traditional energy actually help the environment? One thing to keep in mind is your overall carbon footprint. For example, if you spend a lot of time in the car and have an electric vehicle, you can use solar energy for your home to power your EV and therefore help offset your carbon emissions.In fact, if you make the switch to solar power, you could look forward to lowering your carbon dioxide emissions by about 50 pounds each year. As you can see, using solar power has so many other benefits apart from saving money. One of the most important ones is that you can help save the planet too.
