Hello,
with my first 2x solar panels (each 395W), I purchase a standard mounting rack.
2x ground panel with profile to mount the triangles on grass roof
2x triangle element (3x each L bracket aluminum 40/40 & 3mm thick connected with M8 srews)
Panel itself will be mounted vertical on parallel PV-alu-profils 40x40 fixed with M10 screws on the triangles..
As we have strong winds & flat roof, I would like to get your experience on if the 2 triangle with 4mm material are strong enough.
Idea is to make in total 4 triangles & make cross connections on rear with 25x2mm aluminum strips for side support of each two.
40x4mm alu is support 2500kg pull force at least follow the math...not considering both L sides.
For keeping it on the roof - I calcuated with 133kg per square meter panel. So 450kg stones to load on base for both panels.
Looking for you remarks & thanks in advance!
