Methodology: How We Ranked the Best Solar Companies in Fairfax

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


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 Fairfax

When choosing a solar company, most homeowners or business owners think about the costs above all.There are quite a few factors you should take into consideration when trying to figure out how much it will cost and how much you can save, including:

  • The model of solar panels you want to get: More efficient panels are more expensive, so that will determine your budget for your solar project.
  • Incentives: One thing 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 a decent amount of money on your energy bills, which can result in an average of $32,000 of savings over 20 years.
  • The amount of sunlight your roof gets: Because of Fairfax’s very high amount of average daily sunlight, you should be able to save a lot on your electric bills.
  • How much energy your home consumes: Homes that need lots of electricity each month may call for more solar panels and, as a result, be more costly, but will also enjoy more savings over time.

Due to solar panels now being cheaper than ever as well as various solar incentives, they are a sound investment for many homeowners.

Solar Incentives in Fairfax

If you’re considering making the switch to solar energy, a number of government incentives and solar rebates can drastically bring down the cost of the project and speed up the return on your investment.In addition to the federal tax credit incentive, there are also some state- and city-level incentives, which in most cases, stack with the federal incentive, so you get to save even more. For detailed information about local incentives, see our article on solar incentives.

Environmental Impact of Switching to Solar in Fairfax

One of the most compelling reasons to switch to solar power is to minimize your reliance on traditional energy sources like burning fossil fuels, which are hazardous for the environment.A question many homeowners might be asking themselves is how much can they really help protect the environment by going solar anyway? The average person has a sizable carbon footprint. Between their car, which releases over 10,000 pounds of carbon dioxide emissions a year, and electricity for their home, it can be overwhelming to figure out what to do. Using solar power is a simple thing you can do to help.Since solar panels don’t release greenhouse gas emissions into the atmosphere when generating electricity, they’re a good substitute for nonrenewable energy sources. In fact, you could reduce your carbon dioxide emissions by about 50 pounds each year. The great things about solar power are abundant — just like solar power is! That's why so many people have been happy with making the switch to solar.

EcoWatch's Fairfax, CA Solar Company Rankings FAQs

Which solar installation company is the best in Fairfax?

In Fairfax, SunPower Corporation is the top local solar company. Our team of experts rates it 4.50 stars, so it's a good choice if you're looking to add solar panels to your roof.

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

The advantages of solar power are that it can lower or, for some, completely eradicate your electricity bills, improve your home’s value and reduce your carbon footprint. The biggest disadvantages are that solar panels can be costly to install, you may not see as many savings if you don’t use a lot of electricity and it doesn’t work for all roof types and locations.

How long does it take for solar to pay for itself?

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

How long do solar panels last?

Even though the average lifespan of solar panels is 25 to 30 years, that doesn't mean they are completely unusable. What this means is the amount of energy they produce will have decreased significantly after that point. You can decide to replace them after having them for that long or you can continue to use them at a lower efficiency after that time.

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.
