350 watt panels with rec 370 WATT PANELS

[Michaelzz28]

Does anyone have any ideas if I mix in two REC 370 watt panels in a string that has 8 REC 350 watt together into a combiner

no one?

in a series string, my guess is the 370w would be reduced to 350w . I'm assuming same panel family, just binned into 350, 360 & 370 w catagories

The more panels in the series the more the difference is skewed off.

Depending on the size of the build, could be cheaper to get a second SCC.

If the current rating of the 370W is equal or slightly more than the other panels in
the series string, performance will be nearly identical to just adding more 350
watt panels. Bruce Roe

If there is a big difference, you may be able to do it and avoid the penalty by adding a Tigo optimizer to the panel
