TacomaSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Tacoma homeowners installing in 2026 cannot claim the federal residential credit. What remains is Tacoma Power net metering. At 3.9 peak sun hours a day, a home with a $95/month bill (about 679 kWh) needs roughly a 7.2 kW system — 18 panels — and pays back in about 15 years.
Solar Incentives Available in Tacoma
The federal residential credit does not apply to a Tacoma system installed in 2026. Washington does not add a state income tax credit in this dataset. Tacoma Power sets the local rules for crediting the solar power you export.
Tacoma Power is municipally owned with very low rates, so Washington's sales-tax exemption and self-consumption drive the payback.
