Generous solar tax credits and incentives can substantially reduce the cost of installing a solar electric system. Your sales consultant will go over these with you during your free site visit. Below we have listed the current incentives that apply to most Oregon and Washington residents. Please note that incentives and tax credits can change frequently, and are generally lowered or eliminated with short notice.


Net Metering
Net metering is an agreement between a residential or commercial customer and their electric utility to allow consumer generated solar power to be feed into the grid and credited towards the customer’s account (your meter spins backwards!). Whether you consume the electricity or feed it back into the grid, you will see the savings on your electricity bill.

Residential Incentives
Federal Tax Credit: 30% of the system cost, minus utility incentive.

Commercial Incentives
Federal Tax Credit: 30% of the overall cost.


Sales Tax Exemption (Residential & Commercial)
Solar installs receive a sales tax exemption (8.5-10% savings) through June 30, 2018. This covers the full installed price for installing a solar photovoltaic system smaller than 10kW (covers most residential systems). For larger systems, customers must pay sales tax upfront, but are eligible for a 75% remittance immediately after a system is installed.

Production Incentive (Residential & Commercial)
In addition to not paying for the electricity offset through net metering, the State of Washington pays solar customers a production incentive ranging from $0.15-$0.54/kWh with a maximum incentive payment of $5000/yr. The rate for the production incentive is based on the source of the equipment. Below is a breakdown of incentives for various system configurations.

  • Out of state solar modules with an out of state inverter = $0.15/kWh
  • In-state solar modules with an out of state inverter = $0.36/kWh
  • In-state solar modules with in-state inverter = $0.54/kWh

For example if a fully made in Washington system that produces 5000kWh/yr will receive an incentive payment of $2700 ($0.54 x 5000kWh) each year until 2020.
