Are solar panels worth it for Seattle City Light customers?

Probably not. Washingtonians enjoy extremely low electricity prices because of the state's vast hydroelectric generation resources. This is very good for your pocketbook as a utility customer, but it means that solar panels pay you back much less here than they do for people in other states. Add to that the fact the King County is awfully cloudy during much of the year, and you get an equation that doesn't add up.

Does Seattle City Light offer net metering credits for exported solar power?

Yes, Seattle City Light offers net metering credits.

Under the Seattle City Light net metering program, solar panels will first send energy to your home. Any excess solar energy is sent to the grid and purchased in the form of a bill credit. The credit value is determined by the Tri-Party Net Metering Power Purchase Agreement. KUA customers are billed for all of the electric energy delivered to them by the company.

Excess generation credits expire on April 30th of each year.

What incentives, tax credits, and rebates are available to SCL customers for installing solar?

The biggest financial incentive for solar homeowners is the 30% federal solar tax credit. The tax credit equals 30% of the solar installation costs and directly reduces your federal income tax liability.

Some states and local governments offer additional solar incentives. These incentives include state tax credits, rebates, or performance-based incentives like Solar Renewable Energy Credits (SRECs). The best part is that these local incentives can be used in addition to the federal tax credit!

Here is every incentive you may be eligible for as a SCL customer:
