Kiwa PVEL, an independent solar testing organization, named Qcells a "Top Performer" in all eight categories of its 2026 PV Module Reliability Scorecard, released Tuesday.
The assessment evaluates how solar panels withstand harsh conditions, including extreme heat and humidity, rapid temperature changes, mechanical stress and hail impacts.
The results included modules produced at Qcells' manufacturing facility in Cartersville, Georgia, which completed construction in July.
The company also received the highest overall rating, "Overall Highest Achiever," in the Renewable Energy Test Center's (RETC) PV Module Index Report released in May.
RETC evaluates solar modules across three areas: reliability, performance and quality. Qcells earned top ratings in all three.
The results come as Hanwha Qcells expands its U.S. manufacturing operations through its Solar Hub project in Georgia, which integrates the production of ingots, wafers, solar cells and finished modules.
The Cartersville facility is expected to reach full production capacity across all manufacturing lines by the end of this year, according to the company.
The U.S.-made modules also help solar projects qualify for additional federal tax credits.
Qcells said it had already secured sales contracts for most of its planned 2027 module production at Cartersville and was pursuing additional supply agreements for 2028 and beyond.
"Recognition from PVEL and RETC underscores the strength of our manufacturing capabilities and our commitment to producing high-quality, dependable solar modules," said JK Hong, head of manufacturing at Qcells.
"We will build on this achievement as we continue to scale a US solar supply chain in Georgia," Hong added.
