Got my roof mounts in.
The only big thing is to get the insufficient lam beam made from three 2x8 boards. It can't even hold up my buildings roof with out sagging. Definitely not going to hold another 700 pounds of solar panels out of my building and replace it with a 24 foot I beam that I got at the scrap yard.
My mechanical engineer says my steel I beam should be at least as strong as a lam beam using four 2x12s.
A special order 24 foot long 2x12 costs around $100 each. This old steel I beam was $37.
A new steel beam would cost at least $600.
The electrician needs to pull permits for my tie in and install. Guess he will do it when he needs money.
