Solar panel hot spot in the frost

[andreww]

Would appreciate anyone's input on the attached photo, from a customer I've installed.

There is obviously temperature variation across the panel, but one cell looks particularly hot and hasn't formed any frost.

Everything seems to be working normally but the customer is a bit worried. I'm stumped!

Panel is an ET 235W poly.

Any help in the puzzle much appreciated!

Would it be worth checking with a thermal imaging camera when the system is producing well,
see the sample picture I have included for you.

This would confirm if you do have a weak cell or not.

I hope this helps

Looks like that cell has a high resistance hence produces more heat than electric, the bypass diodes should cope with it ok.

As Earthstore says, a thermal picture will give a good overall view, I'd not worry too much unless it shows a blockbuster winning matrix!!

Not meaning to offend robinhood005, but is your post written in some sort of code??
I have not got a clue what you are trying to say.
