Need help sunpower 305 watt

[repoman]

I have these 54 volt sunpower 305 panels I bought off Facebook market. Cannot find any information on how to mount them ..they have an odd looking fiberglass frame. I'm hoping someone has dealt with these before..they may be 5 to 7 years old..any help would be appreciated...I was told by the guy I bought them from they were made for flat roofs and didn't need mounted and could withstand 125mph wind without lifting up

Can you post pics? I'm a "Murphy's Law" kinda guy I can not believe that anyone could recommend laying panels flat without any type of fastener?

In any case, all my own panels are mounted onto unistrut members, bolted on with 1/4" galvanized screws.

If the frames are fiberglass, I'd investigate what kind of grounding attachments these panels possess.
