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 are outlined in the Administrative Rules​.

Qualified PV systems must:

  • Be installed or verified by an ODOE-ce​rtified 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.
