Solar power in Seattle, Washington

Seattle Light provide net metering and support performance payments.

The Renewable Energy System Incentive Program pays a minimum of $0.16/per kWh for all energy your solar system produces on top of net metering payments!

Payments increase to $0.21/kWh when state manufactured solar modules are used. This incentive is a contract signed for 8 years or until 50% of the system has been payed off. State manufactured components will set you back a little more on day one but will result in the best returns.

The federal ITC also allows part  of the system cost to claimed as a deduction to federal income taxes; it's worth 26% in 2020, or 22% in 2021. This incentive can be used in increments to suit anyones financial position.

With part of the costs covered by the ITC, net metering and outstanding performance payments you'd be pretty silly not to install solar while these generous incentives are available.

Even if you still aren't sure solar is the right decision fo you a free estimate by entering your current bill spend and address can never hurt.

Net Metering Broken Down

Under net metering excess solar generation is credited at 1 for 1 with retail prices. When more energy is exported than drawn in a month credit is carried over at the same rate for future bills. Unfortunately, remaining credit at the end of the yearly billing cycle expires without compensation.
