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 District Of Columbia 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 many readers, the decision of which solar installer to hire comes down to how much it’ll cost.The overall price and potential savings vary depending on a few important factors such as:
- Choice of solar panels: The kind of solar panels you want will affect your total cost. High-efficiency monocrystalline panels are more expensive upfront but can also lead to more savings over the lifetime of your system. If you don’t need to maximize efficiency, you can opt for a higher number of more affordable panels.
- Your location: This affects how much sunlight your roof gets, which helps determine how many panels you need.
- The cost of electricity in your area: If your local energy rates are quite high, there's a good chance you'll end up with a higher return on your investment in a solar system. In Washington, you can save an average of $999 a month on your electricity bills.
- Incentives: Along with the federal Solar Investment Tax Credit (ITC), which lets you deduct 0 of your overall installation cost, your state or local government may offer additional tax exemptions, credits or rebates that can help you save even more. Aside from incentives, you can save an average of $12,000 over the first 20 years with your system, too.
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 a number of factors, like the amount of daily direct sunlight available and your current power bills.
