Residential Incentives



Federal Tax Incentive:

In an effort to help people embrace renewable energy, the Federal government is offering a 30% tax incentive on the full cost of installing a solar PV system through 2019, including:

  • Solar PV panels, inverters, and sales and use taxes on the equipment
  • Installation costs and racking for both roof and ground mounting
  • Step-up transformers, circuit breakers, and surge arrestors, panel upgrades
  • Energy storage devices, power conditioning equipment, and transfer equipment

If the full amount of this credit is not used within the tax year it is earned, it can be carried forward and used in future years till 2022. This tax credit can be used on the homeowners primary and secondary homes. This federal tax credit is scheduled to be reduced in 2020 to 26% and 2021 to 22% and expires in 2022.

State Tax Incentive:

The Utah Investment Tax Credit is calculated at 25% of the total system cost with a cap of $2,000. A typical sized system will reach the cap of $1,600.

Financing options are available with no upfront costs and similar monthly payments as your current electricity bill with qualified credit.

Net Metering:

This process is the billing arrangement with your utility that allows you to receive credit for excess renewable electricity delivered to the grid. When a residential net metered solar PV system produces electricity, the electricity first serves the home's onsite electricity demand and any excess electricity is provided to the utility grid.

If the residential solar PV system generates more electricity than the home uses during a given billing cycle, net metering customers receive bill credits which can be used to offset future usage. The goal is to design the PV solar system to over-generate power in the summer to off-set the limited productivity during the winter months. This is how to eliminate 100% of your electricity usage during the year.



Governed by RCW 82.16.165, a Production Incentive is paid per kilowatt hour (kWh) to those who install solar based upon the size of the solar system, date of certification/installation and whether or not the solar modules are Made in WA.

Fiscal Year EndsBase Rate: ResidentialBase Rate: CommercialBonus for Modules made in WA

Solar systems of 1 kW through 12 kW are classified as "residential" regardless of the type of facility where they are installed. Solar systems larger than 12 kW are classified as "commercial" unless they are installed as a Community Solar Project.

Participating utilities read the newly added Production Meter and report readings to solar customers. Production Incentive payments are made annually following the June 30 state fiscal year-end. Payments last for 8 years or until payments add up to 50% of the total system cost including sales tax, whichever occurs first.

Systems installed after 6/30/2021 do not receive a WA State Production Incentive.

Further, there exist upper caps (limits) - per utility - on the total dollar amount that can be paid out for Production Incentives. The WSU Energy Office website shows these caps as well as progress toward reaching the caps. Additionally, there exists an overall cap on the total amount of money available for this Incentive Program.

The Washington State University (WSU) Energy Program, which is the administrator for this

  • incentive program, is accepting the following types of applications:
  • Incentive
    Application for Residential-scale or Commercial-scale renewable energy systems
  • Precertification Application for Shared Commercial Solar or Community Solar Projects

Applicants will use this online account to:

  • Create and submit a new incentive application
  • Check the status of their application as the review process gets underway.


The Solar Investment Tax Credit ("ITC") is a federal tax credit for solar systems placed on residential (under Section 25D) and commercial (under Section 48) properties. In December 2015, Congress acted to extend the 30% tax credit through 2019 with a step down in subsequent years: to 26% in 2020, to 22% in 2021, and thereafter it is 0 (zero) for homeowners and 10% for businesses. Link to SEIA's website with a breakdown on the ITC.



Oregon Energy Trust incentives for PGE and Pacific Power

Your Energy Trust cash incentive amount depends on the size of your system and your electric utility.

Portland General Electric$0.60/watt$4,800 maximum incentive per home
Pacific Power$0.55/watt$4,400 maximum incentive per home

These incentives apply to solar electric systems owned by the homeowner.


Incentives are available on a first-come, first-served basis.

Our 2018 budget is $150,000, and we will periodically review remaining funds. Incentive levels are subject to change and may end at any time.

Update (Jan. 29): We have allocated 35 percent of the 2018 incentive budget.
