SpokaneSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Spokane homeowners installing in 2026 cannot claim the federal residential credit. What remains is Avista net metering. At 4.4 peak sun hours a day, a home with a $100/month bill (about 714 kWh) needs roughly a 6.8 kW system — 17 panels — and pays back in about 13.5 years.

Avista offers net metering in Spokane, and Washington's sales-tax exemption on solar lowers the up-front cost.
