Balcony Solar in Washington
Everything you need to know about plug-in and balcony solar law in Washington, plus what it means for what you're allowed to plug in, and what it saves.
Is it legal?
Currently unregulated - legislation in progress.
Washington's SB 6050 was introduced in the 2026 legislative session but was deferred to 2027, where it will be reconsidered. Until Washington passes plug-in solar legislation, the technology sits in a legal gray area: utilities can require interconnection review, permits, and fees, and there are no explicit statutory protections for consumers. If passed, the bill would clear these barriers, allowing small solar systems to connect to standard household outlets without utility approval, permits, or an electrician.
Bright Saver's policy team is working to support legalization efforts across all 50 states.
Bright Saver's 180W and 360W kits can be shipped to Washington and we welcome early adopters.
What You Can Save in Washington
Washington's average residential electricity price is about 11.5 cents per kWh (EIA, 2026 average). A 180 W kit generating about 270 kWh a year could save roughly $31 a year; a 360 W kit roughly $62.
Washington's rates are among the lowest in the country, so absolute savings are modest. The kit more than pays for itself over its life with no roof work or contractor needed.
