- Both tested model types and their variants for which the results are representative are included in the list of Top Performers. Model types are presented on multiple rows when multiple BOMs of the same model were tested. These BOMs are differentiated via the BOM ID column.
- For MSS, the mounting used is shown as follows:
- 400 mm Nextracker mounting, tested at ±1800 Pa for SML.
- 790 mm Nextracker mounting (no 400 mm holes present), tested at ±1800 Pa for SML.
- Corner mounted along the short-sides using Snap-N-Rack hardware, tested at ±1800 Pa for SML.

The 2026 Top Performers Search Tool
Search through this year’s Top Performers by PQP Test, Manufacturer, Module Design, Cell Technology and more. A checkmark means the model type is a Top Performer in that test.
Search results are listed in alphabetical order by the manufacturers’ number of Scorecard appearances. The default search setting shows only the models that have achieved Top Performer status in all reliability tests (TC, DH, MSS, HSS, PID, UVID and LID+LETID).
