Solar plumbing help

[Nova13]

Mystery solved, one of the panels has leak, early in the morning I see a drip under one of them.

I guess in the heat it evaporated before I could see it.

I'll flip it over, I was told a few golf tees and silicone works.

any better ideas?

thanks for your help

I haven't repaired any leaks but a stainless steel screw might be better than a golf tee.
