REC modules went with 2 cross bars in their frame when going to 72 cell. I\u2019ve been observing frames get thinner over time - wondering how a 30 mm frame could do the job on 72 cell mods when we used to have twice that on 60 cell mods. It\u2019s great to save aluminum and weight but not at the expense of panel life. Can\u2019t imagine the impact resistance goes up with less support never mind possible degradation to the wafers due to flexing? <div><br></div><div>Any panel manufacturers on the List that can comment?
