Hi there,

Do any of you experienced chaps know what would the likely maximum module temperature would be in the uk? I am just checking the compatibility of various modules with an inverter and have hit a snag. The panel i have selected works fine until the max temperature goes over 35 deg C. I would guess that module temp would be in excess of ambient temp but Im not sure by how much. Of course I dont want to install something that wont work when it gets too hot but on the other hand there is little point searching for a panel which works up to 75 deg C when we are very unlikely to ever see such temperatures. From testing our panels before installing I have never seen one above 25 deg c but then I would expect it to rise considerably when installed with the sun shining on it all day.

Your thoughts would be appreciated.
 
I'd say top end would be around 65deg to be safe, but it's going to be pretty rare to get above 55-60. I've definitely done installations where the panels are too hot to touch for longer than a few seconds, so reckon those numbers are about right.

they will definitely go significantly above 35 degrees though.
