Seattle has a reputation for gray skies, so many homeowners assume solar won’t pay off here. It does. Our long, bright summers produce a lot of energy, and Seattle City Light’s net metering program lets you bank that summer output against your winter bills. Here’s how going solar works if City Light is your utility.
Why Go Solar as a City Light Customer?
City Light is one of the cleanest utilities in the country, and most of its power comes from hydroelectric dams. So for City Light customers, solar is less about cutting carbon and more about energy independence and long-term savings. Rates have gone up steadily over the last decade. Panels lock in a big share of your electricity at a fixed cost for 25 years or more, and that protects you from future rate increases.
How Net Metering Works
When your panels make more electricity than your home uses, the extra flows back to the grid. City Light credits your account for it, and those credits roll forward to cover later bills. In practice, you build up credits from May through September and draw them down in the darker months.
Washington’s net metering law guarantees this arrangement for now, but it’s set to be reviewed in the coming years. Homeowners who go solar sooner are generally in a better position to keep today’s terms.
Get Your Energy Independence
The Interconnection Process
Connecting to City Light takes a few steps. A good installer handles all of them for you:
- Site assessment and design. Your installer looks at your roof’s direction, shading, and condition, then sizes the system to match your annual usage
- Net metering application. This goes to Seattle City Light before installation. The utility reviews it and approves the system.
- Permitting. The City of Seattle requires electrical permits and an inspection.
- Installation. Most residential installs take one to three days.
- Final inspection and meter swap. After the system passes inspection, City Light installs a bidirectional meter and gives you permission to operate.
From signing the contract to turning the system on usually takes six to twelve weeks. Permit and utility timelines account for most of that.
What About Incentives?
The federal tax credit for homeowner-owned systems ended at the end of 2025, so the math looks different now than it did a few years ago. Solar can still make financial sense in Seattle, especially with rising rates and financing options that keep upfront costs low. An honest installer will show you real payback numbers based on your actual City Light bills, not inflated estimates.
Is Your Home a Good Fit?
The best candidates have south-, west-, or east-facing roofs with limited tree shade and at least 10–15 years of life left in the roofing. Even partly shaded homes can often work with the right panel layout.
