Marks and dirt on new panels

oldskoo1

Hi all

I noticed some light markings on some of my panels. They appear to be on a few panels from what I can see.

They appear lighter/white in colour, usually in the centre of the panel and approx a couple or so inches in length, but thinner.

As they are on several panels I'm wondering if it's suction handling from the factory.

I did raise this on install, the installers said it could be off their gloves or silicon. They said they had wiped it off but looking again recently the marks are still there.

Any ideas what they could be? My generation is good but I'm curious and hope there is no glass damage for when the frost comes.

Also appears most of the panels were dusty and now has dusty line streaks after all this rain.

Thanks

The marks seem a little too similar between several panels for it to b the birdies. They have only been up a few days and I noticed the mark on the nearest panels from the velux on day 1.

Looked up during late evening diffused sun tonight and noticed the mark visible of a,few more panels.

Stumped what it is.

When I had my WNW installed(same installer oldskoo1) I noticed one panel with a thick layer of dust and a couple with markings. Dust has gone as has the markings. If they're generating as they should be I wouldn't worry, like anything new you tend to scrutinise, believe me, if they've been rained on and are generating fine there's nothing to worry about.
