Damage to new solar panels.

I'm new to solar and not sure what imperfections/damage is unacceptable.

I have received a new panel from a UK supplier but unfortunately it looks like one of the cells is cracked, should i be concerned?

I would send it back without asking here but it was on a good discount and the service I have received from them has been poor and could end up waiting/chasing them. I appreciate there are current supply issues but 3 out of 3 orders over the last few months have had items out of stock even though listed as in stock.

I think you will lose the energy generated by this area, maybe 1W of power.
So it is maybe not worth the trouble.

If it is a full crack, the cracked-off portion will go dark orange then ultimately burn out with possible backsheet fire. Just not acceptable to be supplied this as new.
Best of luck finding another supplier.
