How to choose a solar installer in Washington

Check licensing & certification

Solar installs in Washington involve electrical work, so the contractor (or their electrician) needs the proper state license. Favor companies with NABCEP-certified staff, the industry's recognized credential, and confirm they carry liability insurance and a workmanship warranty, not just the manufacturer's panel warranty.

Get three quotes and compare price per watt

Quotes vary widely. Compare the total cash price divided by system size (dollars per watt) rather than the monthly financed payment, which can hide markups. Make sure each quote lists the same panel and inverter brands, the production estimate, and exactly what's included.

Confirm permits, interconnection & net metering

A reputable installer pulls the building/electrical permits and files the utility interconnection paperwork for you. Ask how net metering works with your local Washington utility: it determines how much credit you earn for excess power you send back to the grid, which drives your real savings.

What to know before hiring in Washington

The largest utilities serving Washington homes are Puget Sound Energy (1,091,599 residential customers, 14.6¢/kWh), City of Seattle (459,964 residential customers, 14.1¢/kWh) and PUD No 1 of Snohomish County (346,532 residential customers, 11.5¢/kWh). Your utility sets the rate your solar production offsets, and it is also who an installer files interconnection or service paperwork with, so name it when you ask for quotes.

Check the license before you sign

Electrical contractors in Washington are licensed by the Washington State Department of Labor & Industries. Electrical contractor license (general 01 or specialty) with a certified administrator and bond; electricians are certified by L&I.
