Methodology: How We Ranked the Best Solar Companies in Washington

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


Below are some the criteria we examined specifically for Wisconsin 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 Washington

When deciding on a solar company, most homeowners or business owners worry about the costs the most.There are a few factors you should take into consideration when trying to determine how much it will cost and how much you can save, including:

  • How much energy you use: If your household regularly uses a lot of energy, you'll benefit more from switching to solar.
  • The amount of sunlight your rooftop gets: Because of Washington’s relatively low amount of average daily sunlight, you might not see as many savings on your energy bills.
  • The model of solar panel system you can buy: This is dependent on how much you’re willing to invest upfront.
  • Incentives: Tax-paying citizens who buy and install a solar energy system this year can save 0 of their installation costs by using the federal solar investment tax credit. You can also save about $19,000 on your utility bills over 20 years not including incentives.

Although a solar panel system costs a sizable chunk of money upfront, it can save you thousands of dollars over time. The question of how much, though, depends on a number of factors, like the size of your solar panel system and your local electricity rates.

Environmental Impact of Switching to Solar in Washington

Installing solar panels is a great way to do your part for a more environmentally-friendly future.Many homeowners might be wondering how much exactly they can impact the environment by switching to solar in Washington, though. For homeowners and business owners who want to help cut back on greenhouse gas emissions, switching to solar power is an easy choice, especially since Washington produces a very high amount of carbon dioxide emissions from its energy generation.Although solar panel production releases carbon dioxide emissions, the panels make up for it by greatly lowering the amount of CO2 you would have been responsible for if you still used nonrenewable energy.
