Methodology: How We Ranked the Best Solar Companies in Vashon
EcoWatch's solar experts analyzed each solar company in Vashon 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 Vashon
Below are some the criteria we examined specifically for Washington 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 Vashon
For many people, the decision of which solar installer to go with comes down to how much it’ll cost.There are several factors you should consider when trying to figure out the overall cost and how much you can save, including:
- The model of solar panels you’re planning on getting: More high-tech panels are more expensive, so that will determine your budget for your solar project.
- Incentives: Those who purchase and install a solar system this year can save 0 of their solar installation costs by using the federal solar investment tax credit. You can also save about $17,000 on your electricity bills over 20 years without incentives.
- How much energy costs for you: If your local energy rates are high, there's a good chance you'll have a higher return on your investment in a solar system. In Vashon, you can save an average of $1,276 a month on your electricity bills.
- How much electricity your household consumes: Households that need a lot of energy each month may need more solar panels and, as a result, be more costly, but will also save more on their energy bills over time.
