Not sure anyone will know, but looking for opinions.
Getting prepared to install ten 4x12.5 Heliocol panels and can not decide how many mounting pads I need to buy.
The manual suggests:
Later it goes on to suggest using 4 mounts per bank on a flat roof (1 in each corner).In general, allow two mounting pads on the upper header of each panel, and one for the lower header. (On roofs with a pitch greater than 10/12 you need more pads, and on flat installations you can use less.)
Well 10/12 is a 40 degree pitch above which you want 4 pads per panel instead of the normal 3.
I will have 2 banks (4 and 6 panels) and my roof is close to flat at 8 degrees. So based on their manual I need between 30 pads (3 per panel) and 8 pads (4 per bank). At close to $10/pad, these start to add up.
I was thinking of maybe going with 2 pads per panel (1 top and bottom) since my roof is close to flat (although it does not have the little walls around the roof like you see on true flat adobe-type roofs).
And experts out there ... or anyone wanting to throw an opinion at me?
