Methodology: How We Ranked the Best Solar Companies in Norwalk

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


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 Norwalk

The cost of installing solar panels has dropped significantly in the past several years, but it's still a significant investment for most homeowners. Some significant things that influence the upfront cost and potential savings over time include:

  • Average daily sunlight: Since Norwalk gets lots of sunlight, your solar panel system will most likely be able to generate enough energy to power your whole home, which affects how much your electricity bills will be.
  • How much energy costs for you: The typical family in Norwalk pays around $750 a year on energy alone, so you could gain that much in savings.
  • Incentives: Something that can save you money on your solar project 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 energy bills, which can lead to an average of $25,000 of savings over 20 years.
  • The kind of solar panels you can purchase: This is dependent on what your budget is.

There are several good benefits of solar despite the upfront cost of installation. It can help the planet and your finances. Additionally, it can increase the value of your home, resulting in even more benefits if you choose to sell your home later.

Solar Incentives in Norwalk

In an effort to increase the adoption of solar power, federal and local governments — and even some utility companies — offer incentives to help make switching to solar power more financially viable and accessible. You qualify for the federal solar investment tax credit (ITC) for the tax year you turn on your solar panels. You can also potentially use the ITC with other state and city rebates and benefits. Check out our article on solar incentives to find out what incentives you can benefit from.

Environmental Impact of Switching to Solar in Norwalk

There are a few important reasons why many people are interested in solar energy: for the good of their bank accounts and the planet. But — how much exactly can you help by going solar? One thing you should 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 install solar panels on 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. Since energy from the sun is renewable and produces electricity without a carbon footprint, installing solar panels is one easy step you can take to help the environment.

EcoWatch's Norwalk, CA Solar Company Rankings FAQs

Which solar installation company is the best near me?

In Norwalk, Solar Energy Hardware is the top local solar company. Our team of experts rates it 3.00 stars, so it's a solid choice if you're looking to add solar panels to your house.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be harmful 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 needs 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?

Solar panels generally pay for themselves in about 7.3 years, but your solar payback period will vary depending on your utility costs. The higher your typical electricity bill, the quicker your solar panel system will pay for itself.

What is the efficiency of solar panels?

For the most part, solar panels are about 15 to 25% efficient, which means they can convert that percentage of the energy from the sun into usable electricity.
