1800BH solar panel fastening

[msctech]

Hello. 3 questions.

First question is for anyone who has an 1800BH who installed solar panels: what screw length did you use as I want it to be strong however not to penetrate into the ceiling inside?

Second question is anyone who installed solar panels, did you fasten the panel directly to the roof or used angle iron (or aluminum tubing) and fasten at either end then fasten the solar panels to the angle iron?

Also my Heliene 72m-320 solar panels didn't come with mounting brackets. Is there a generic bracket that would work with them or do I need to measure as there may not be a standard from one solar panel manufacturer to another?

The panels I used came with 'feet' brackets that you attach directly to the roof. I basically used screws that would be just long enough to penetrate the roof deck entirely +1/4 inch for the thickness of the feet + the sealant that I used to "glue" the feet to the roof membrane.
