Washington exempts solar energy systems from state and local sales and use tax. The exemption is 100% for systems that produce at least 1 kW and up to 100 kW AC, for the equipment, and installation by a qualifying registered contractor can be exempt too. Equipment must be bought, and installation completed, by December 31, 2029.

OPALCONet metering
OPALCO members with grid-tied solar can net meter. When your array makes more electricity than you use, common in summer, you earn a credit for the power you send back to the grid. When you use more than you make, common in winter, your bill reflects what you drew from the grid, what you generated and any credit you earned.
| OPALCO 2026 tariff | Rate |
|---|---|
| Renewable generation credit (power you export) | $0.0990 per kWh |
| Grid usage charge (on exported power) | $0.0137 per kWh |
| Net credit for exported power | about $0.085 per kWh |
| Residential DER service access charge, billed even if you use no grid power | $67.58 per billing period |
