Home Rooftop Solar Panels
Residential photovoltaic (PV) systems, often referred to as rooftop solar panels, convert energy from the sun into electricity. Systems are usually connected to your utility-provided electric service. Other systems include battery storage with capability of operating when there is no utility connection.

Certain photovoltaic systems installed in your Oregon home may be eligible for a Residential Energy Tax Credit.

RETC Qualifications

A​ photovoltaic system must meet certain qualifications to earn a Residential Energy Tax Credit​ up to $6,000 (credit taken over four years), depending on the solar capacity of your system. See the RETC Rate Chart for more information.

Complete qualifications and instructions are outlined in the RETC Application.

Qualified PV systems must:

  • Be installed or verified by an ODOE-certified tax credit technician​​.
  • Have a minimum installed capacity of 200 watts.
  • Have a minimum Total Solar Resource Fraction (TSRF) of 75%. TSRF is the fraction of usable solar energy that your panels should collect, based on shading and the tilt and orientation of the panels.

Note: The RETC program is scheduled to sunset on December 31, 2017. RETC devices must be purchased by December 31, 2017, operational by April 1, 2018, and applications must be received by ODOE no later than June 1, 2018.​


Your installing technician will help you complete the RETC application process through an online system called PowerClerk. Your installer will complete the application, and you will be notified by email that your application is ready for an electronic signature. Once it is completed by your installer, e-signed by you, and then processed by ODOE staff, you will receive your Tax Credit Certification by email (you will not receive a postcard in the mail like you would other RETC devices).

Emails will come from ​ Please add this to your email address book or check your spam filter frequently.
