Solar pool heating systems
provide free heat by circulating pool water through a solar collector, often on a nearby roof.
Certain solar pool heating systems installed in your
Oregon home may be eligible for a Residential Energy Tax Credit.
A solar pool, spa, or hot tub heating system must meet certain qualifications to earn a Residential Energy Tax Credit
up to $2,500, depending on the system installed and its first-year energy yield. See the RETC Rate Chart
for more information.
Qualified solar pool heating systems must:
- Be new and come with a 10-year warranty or better.
- Be certified by the Solar Rating and Certification Corporation , Florida Solar Energy Center , or other body approved by the Oregon Department of Energy.
- Have a minimum Total Solar Resource Fraction (TSRF) of 75%. TSRF is the fraction of usable solar energy that your system should collect, based on shading and the tilt and orientation of the collector.
Qualified solar spa or hot tub heating systems must:
- Have a design approved by the Oregon Department of Energy.
- Have controls to maintain safe temperatures.
- Have a minimum Total Solar Resource Fraction (TSRF) of 75%.
