Washington State Solar Incentive Program
A proposal for a low-income solar energy program was passed by the Legislature and signed into law on March 30, 2022. House Bill 1814 funds a revised version of Washington’s exhausted solar energy incentive program. In addition to solar for low-income households and service providers, the new program may also fund community solar subscriptions for low-income recipients.Read more
Solar Sourcing and Staffing
With concerns over climate change front and center, and energy prices driving consumer and industry desires to shift to renewable energy, solar power is increasingly attractive. Despite concerns about sourcing and staffing, the prospects for increased solar power installation and usage in Washington is positive.Read more
Solar Incentives, Tax Credits, Net Metering & More
Net Energy Metering
For installed systems, Washington state has a net metering law (RCW 80.60.030) that lets customers of power companies offset their electricity consumption with the production from renewable energy system such as solar panels. Consumers may need to apply to their electricity power provider to obtain the credit for net metering. Many providers have forms on their websites.
The process is straightforward. Net metering customers can purchase electricity from their electricity provider when they need it and can send electricity generated by their solar panels back to the electric grid when they do not need it. A meter records both the electricity from solar panels that is delivered to the power company and the amount of electricity from the power company that they use, spinning forward when you are using electricity from your power company, and spinning backward when you are delivering electricity from your solar panels to the grid. Customers receive a credit if they produce more electricity than they use, or they are charged if they purchase more than the produce.
An electric utility shall make net energy metering available to eligible customer-generators on a first-come, first-served basis until the earlier of either: (i) June 30, 2029; or (ii) the first date upon which the cumulative generating capacity of net metering systems equals four percent of the utility's peak demand during 1996. Electric utilities provide information to the WSU Energy Program concerning their progress on reaching the cumulative generating capacity available to net metering systems in their service territories and this information is updated and available on their website.
In accordance with the law, net metering credits expire on March 31 every year and credits from any excess electricity generation are “zeroed out”.
Sales Tax Exemption
Benefits for installing solar panels include sales tax exemption from Washington State for qualifying solar equipment (ESS Senate Bill 5116). From July 2019 and through December 2029, equipment for solar energy systems smaller than 100 kilowatts is exempt from state and local sales and use taxes. There is also a 50 percent tax exemption available for larger solar energy systems that are between 101 and 500 kilowatts. Different rules apply for systems 100 KW to 500 KW. Customers must complete and provide a Buyer’s Retail Sales Tax Exemption Certificate to the seller.
Federal Income Tax Credit
At the federal level, consumers can receive a 30 percent federal tax credit for solar installations and this now includes stand-alone energy storage devices that have a capacity rating of 5 kilowatt hours or greater. The Investment Tax Credit, or ITC, which was expanded and extended as part of the Inflation Reduction Act that Congress approved earlier in 2022, offers a tax credit for solar systems on residential that can be applied for a dollar-for-dollar reduction in the amount of income tax that would otherwise be owed. The credit drops to 26 percent in 2033 and 22 percent in 2034, then disappears in 2035 unless Congress extends it. The Solar Investment Tax Credit (“ITC”) is a federal tax credit for solar systems placed on residential (under Section 25D) and commercial (under Section 48) properties.
See the Homeowner’s Guide to the Federal Tax Credit for Solar Photovoltaics for more information.
Local Incentives for Energy Efficiency
Many utilities offer incentives and rebates for energy efficiency upgrades that help their customers reduce their use of electricity. Review a comprehensive list of PUDs and utilities in Washington state. Check your utility’s website to find out what they have to offer.
Washington State Renewable Energy System Incentive Program (RESIP)
The Renewable Energy Incentive Program (RESIP) is still an active program; however, it is fully subscribed and no longer taking new applicants. Due to the popularity of RESIP, this program ended June 30, 2021 and the Washington State Legislature has not authorized additional funding at this time. In 2017 ES Senate Bill 5939 directed the WSU Energy Program to launch and administer a new program for citizens and businesses of Washington known as the Renewable Energy System Incentive Program (New Program).
