It’s all about temperature differential the hot side can be hot but you need another heatsink to at least ambient temp. I had an array that was using the 6 70W units and had a ¼” aluminum plate painted black with a heatsink and muffin fan on the “cold” side and was able to charge a 12V battery at about 2.5amps in sunlight when water cooled I could get about 4.5 amps out of it. But that was with forced cooling and 6 wired in series.

They are fun to play with check out the Ferrotech link I posted there is all the tech you want there.
