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 Illinois 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
For a lot of homeowners, whether or not to invest in solar panels depends the most on the cost. A few important factors that dictate the cost of installing solar panels on your home and how much it could save you over time include:
- Incentives: The federal solar investment tax credit, which everyone in the U.S. is eligible for, allows you to deduct 30% of the cost of installing your solar panel system from your taxes. Plus, not including incentives, you can save about $13,000 over 20 years on your energy bills.
- Your home's power bills: Due to high monthly electric bills in Washington, you could save about $890 a year with solar.
- The type of solar panels you're thinking of getting: Higher-efficiency panels cost more, so that will affect your budget for your solar project.
- Average daily sunlight: Since Washington gets a decent amount of average daily sunlight, your solar panels can generally generate enough energy to power your whole home, which influences how much your solar panels can save you on your electricity bills.
Solar is a rewarding investment for most homeowners. You can generate your own power instead of paying for it from the grid and make use of solar incentives, all while helping protect the Earth.

Solar Incentives in Washington

There are several federal, state and local rebates and tax credits that may earn you anywhere from 30% to 50% of your money back after buying solar panels. Check out our article on solar incentives to find out what incentives you can benefit from.
Environmental Impact of Switching to Solar in Washington
One reason so many people are considering adopting solar energy is to help bring down their environmental impact. A question many people might be wondering about is how much can they really help the environment by switching to solar power anyway? According to the EPA, electricity generation is the second largest source of greenhouse gas emissions and about 62% of our electricity is generated by burning fossil fuels. Using solar power can help put a dent in that statistic in a city like Washington that generates a large amount of carbon dioxide emissions each year. In fact, if you install solar panels, you could reduce your carbon dioxide emissions by about 100 pounds each year. For people who want to help the environment, the upfront cost of solar is a small price to pay for offsetting your carbon emissions.
