Net metering availability (date-sensitive)
- Under RCW 80.60.020, utilities have to offer net metering first come, first served until June 30, 2029, or until net metering capacity reaches 4% of the utility's 1996 peak demand, whichever comes first. After that, a utility can move new customer-generators to a different rate or tariff schedule. Source: https://app.leg.wa.gov/rcw/default.aspx?cite=80.60.020 (accessed 2026-10-20)
- Customers who start net metering before that trigger keep being credited under RCW 80.60.030, subject to conditions in the statute. Source: same (accessed 2026-10-20)
- Date-sensitive: some utilities may reach the 4% threshold before 2029. Ask your utility whether it's still offering standard net metering.
Little else at the state level

A note on the federal tax credit
The federal residential clean energy credit (25D) doesn't apply to expenditures made after December 31, 2025. The IRS treats an expenditure as made when installation is completed.

Is solar worth it in Washington?
It depends on your bill, roof and utility rules. Here is an estimate for a home with a $150 monthly electric bill and a south-facing, unshaded roof, before any incentives:
- Residential electricity averaged an estimated 14.40¢/kWh in Washington (January–July 2026), below the U.S. average of 18.19¢ (37 of 51, highest first). Source: EIA Electric Power Monthly, Table 5.6.B (accessed 2026-10-20)
- Small rooftop systems in Washington produced an estimated 1,357 kWh per kW of panels in 2024 (2024 small-scale solar generation divided by average 2023–2024 small-scale capacity). Source: EIA Electric Power Annual 2024, Tables 3.21 and 4.7.B (accessed 2026-10-20)
- Estimated system size: 7.2–9.8 kW, producing about 11,535 kWh a year (estimated).
- Estimated installed cost: $25,500–$44,200 before incentives, using $3.00–$5.20 per watt. Source: Lawrence Berkeley National Laboratory (2024 installed prices, 20th–80th percentile; accessed 2026-10-20)
- Estimated simple payback: 13–31 years. Savings depend on how your utility credits exported energy (see above).
