10 Best Solar Companies in Mercer Island, WA

How To Choose a Solar Company

Installing solar panels can cut your electricity costs and benefit the planet by reducing your carbon footprint. When evaluating if a solar provider is right for you, consider these key factors.

Check Licensing

It's important to hire a licensed solar installer. This ensures that the work is done properly using current best installation practices. Solar energy companies in Washington must hold an electrical contractors' license from the Department of Labor and Industries. In certain situations, the department may also conduct permit inspections to test compliance and the viability and integrity of a contractor's job.

Read Customer Reviews

Look at review platforms such as Google Reviews, the Better Business Bureau (BBB), and TrustPilot to find out what previous customers say about local solar providers. Reviews can give you an idea of a company’s dependability and customer service. Be wary of companies with no reviews or with predominantly negative feedback.

Compare Multiple Quotes

To find a solar installer that fits your budget, get free, detailed quotes from three to five providers. The quotes should outline all costs and list the solar equipment included. Comparing several quotes helps you identify the most cost-effective option.

Ask About the Warranty

High-quality solar installations should have robust workmanship and performance warranties. The workmanship guarantee covers any installation issues like cracks in the panels, poor alignment, or poor wiring. The output warranty ensures an energy generation baseline. Strong guarantees reflect a solar provider's confidence in its installations.

Evaluate Financing and Incentives

Solar energy is great for helping you lower electricity bills over time. Be sure to consider these aspects when considering the final cost and value of solar panels.

• Compare system purchase options: Solar panels may be paid for outright or financed through leases or loans. Check important financing details such as payment schedule, fees, annual percentage rate (APR), and ownership implications when financing your solar system.
• Research federal and state tax credits: A 26% federal tax credit on total solar system costs is available through 2032. Many states also offer incentives. These credits can lead to substantial savings for solar buyers.
• Look into utility rebates: Some utility companies may provide additional discounts to motivate homeowners to install solar panels. Check the eligibility criteria and rebate amounts offered by your local electric utility to estimate the possible savings.
