RETC publishes the PVMI Report is annually. We release a “preliminary release” at the SNEC PV POWER EXPO. To capture the results of any outstanding long-duration test sequences, we publish a “final release” ahead of RE+.

Any PV module models and manufacturers tested at RETC are nominally eligible for inclusion in the PV Module Index Report.

To be eligible for “Overall Highest Achiever” recognition, a manufacturer’s PV modules must have undergone RETC’s Thresher Test program, a beyond-qualification bankability test protocol that “separates the wheat from the chaff.”

Manufacturers of products submitted for other test sequences—such as Hail Durability Testing or CEC certification only—qualify for recognition within specific test categories or disciplines.

The PV Module Index Report summarizes the results of bankability and beyond-certification tests conducted at RETC’s accredited laboratories over 12 months, spanning Q2Y1 through Q1Y2 (e.g., Q2 2025 through Q1 2026).

“Overall Highest Achiever” designation is reserved for those manufacturers recognized for high achievement in all three PV Module Index Report disciplines: reliability, performance, and quality. This award recognizes the best of the best.

“High Achievement in [Discipline Name]” designation recognizes individual instances of high achievement within a specific manufacturing discipline, such as “High Achievement in Performance.”

“Test Category High Achiever” designation indicates that a manufacturer’s product met high achiever criteria within individual test sequences.
