Methodology: How We Ranked the Best Solar Companies in Coronado

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


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 Coronado

Solar panels are powered by a free energy source — the sun — but to take advantage of this you will first need to pay to set up your system.There are several factors you should consider when trying to figure out the overall cost and how much you can save, including:

  • Incentives: Along with the federal Solar Investment Tax Credit (ITC), which gives you a tax credit currently worth 0 of your overall installation cost, your local government may offer additional tax exemptions, credits or rebates that will help you save even more. Aside from incentives, you can save an average of $31,000 over the first 20 years with your solar system, too.
  • The model of solar panel system you can buy: This is dependent on how much you’re willing to spend upfront.
  • Your household's power bills: Based on the high monthly power bills in Coronado, you could save about $1,700 a year with solar.
  • Energy consumption: Installing solar panels may be an expensive investment for homes that don’t use a good amount of energy a month.

Though a solar panel system costs a good chunk of money upfront, it can save you a considerable amount in the long term. The question of how much, though, depends on several factors, like the amount of daily direct sunlight available and your current power bills.

Environmental Impact of Switching to Solar in Coronado

If you’re planning on adding solar panels to your home, one of the principal reasons why may be to reduce your reliance on nonrenewable energy.You may be asking yourself – how much do solar panels help the planet anyway? Something that can drastically influence your carbon footprint is how long your commute is and how much you drive overall. If you go solar and have an electric car, you can significantly reduce your carbon dioxide emissions by charging your car at home.Once you go solar, your carbon dioxide emissions can be cut by about 50 pounds each year. If you want to do your part for the environment, you’ll no doubt recognize that there are many good things about adopting solar energy other than just saving money on electricity.

EcoWatch's Coronado, CA Solar Company Rankings FAQs

What is the best solar panel installer in Coronado?

In Coronado, SunPower by Milholland Electric is the most reputable local solar company. Our team of experts rates it 4.80 stars, so it's a good choice if you're planning on installing solar panels on your home.

What is the negative environmental impact of solar panel manufacturing?

Solar panels can be bad for the environment when manufacturers use toxic chemicals in the construction. Chemicals can make solar panels difficult to recycle 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.

Is it worth putting solar panels on my home?

Solar panels can be a beneficial investment for a majority of homeowners, but truthfully, they might not be worth it for everyone. If your home doesn't get enough sunlight or your power bills are already fairly low, solar panels might not be for you.

When should I install solar panels?

Although summer is the most popular time people install solar panels, the perfect time is actually winter. You can save money since there's less demand during the winter months, and it allows you to be up and running with solar for the more expensive power bills you may get during the summer.

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.
