Methodology: How We Ranked the Best Solar Companies in Westminster

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


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 Westminster

Although solar panels can save you a decent chunk of change on power bills over time, it's important to know the startup costs. The overall price and potential savings vary depending on a few key factors such as:

  • How much sunlight your roof gets: If your roof gets limited direct sunlight, your solar panels won't be able to make as much energy, which will give you lower savings on power bills than a roof that gets a lot of sunlight.
  • Incentives: Something that can reduce the cost of 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 money on your energy bills, which can generate an average of $25,000 of savings over 20 years.
  • How much energy costs for you: The typical household in Westminster pays around $750 a year on home energy use alone, so you could end up with that much in savings.
  • Your income and budget: This shapes what type of solar panels you can afford.

There are several great benefits of solar even with the initial cost of installation. It can help the environment and your finances. In addition, it can increase the value of your home, leading to even more benefits if you want to sell your home later.

Solar Incentives in Westminster

If you're thinking about making the switch to solar power, several government incentives and tax credits can drastically bring down your project costs and expedite the return on your investment. On top of the federal solar investment tax credit, there are also some state- and city-level benefits, which in the majority of cases, stack with the federal incentive, so you can save even more. For more information about incentives that apply to you, visit our article on solar incentives.

Environmental Impact of Switching to Solar in Westminster

If you're planning on adding solar panels to your home, one of the main reasons why may be to reduce your reliance on nonrenewable energy. But how much can using solar energy instead of traditional energy actually help the environment? An important thing to think about is your overall carbon footprint. For example, if you spend a lot of time driving to work, your footprint may be bigger, so adopting solar energy for your house can help offset that. Because solar panels don't release greenhouse gas emissions into the atmosphere when producing electricity, they're a good substitute for nonrenewable energy sources. In fact, you could be looking at reducing your carbon dioxide emissions by about 50 pounds each year. If you want to do your part for the environment, you'll no doubt understand that there are many advantages to adopting solar power other than just saving money on bills. You can also help protect the environment, which some would argue is more valuable.

EcoWatch's Westminster, CA Solar Company Rankings FAQs

What is the best solar company in Westminster?

The top local solar company in Westminster is SunSolar U.S., with a rating of 4.07 stars.

What are the main pros and cons of switching to solar?

The biggest advantages of solar power are that it can decrease or, for some, 100% cut your electricity bills, improve the value of your home and bring down your carbon footprint. The biggest disadvantages are that solar panels can be pricey to install, you may not save a lot if you don't use a lot of electricity and whether you can install solar panels depends on your roof configuration.

How long does it take to see a return on your investment after getting solar panels?

Solar panels usually pay for themselves in about 7.3 years, but your solar payback period will depend on your utility costs. The higher your typical energy bill, the quicker your solar panel system will recoup your installation costs.

How long do solar panels last?

On average, the lifespan of solar panels is about 25 to 30 years. Some even last up to 50 years, but efficiency goes down by about 0.8% each year. You can choose to replace them sooner if you want to maintain a larger level of energy production.
