Heyo all,
I'm new to the forum, studying for the Nabcep exam on the 11 April so just trying to absorb as much knowledge as possible. Any tips from past pupils more than welcome. I know this one is a little easy but I done a question early this morning and was wondering if someone would verify my answer.
The installation calls for (10) PVmodules that are 62? inches by 39? inches in size. The modules will be mounted in 2 rowsof 5 with 1 inch between modules for mid-clamps and 3 inches on both ends of each rowfor end-clamps. Based on the rule of no more than 2 feet at the end of rails and 4 feetbetween attachments, how many attachments must be used?
No trusses are mentioned so I don't think that's a factor, I got "20" attachments, the answer sheet says "24" but I think the source may be wrong.
