[RE-wrenches] Silicon Energy install steps?

[Jesse Dahl]

So far to me it seems like another thing is that an install has to go from column to column and all the "trays" or "shoes" have to remain very loose until after their column has had the modules installed.

Thanks,

Jesse

You have to snap lines and measure corner to corner to get yourself as close as possible to perfect square so you give yourself the best chance in getting the modules to slide up easily.   Advice: measure between "trays" or "slide channel" before bringing each module to the roof.   Ditto bclark to start with first column and work to next column.
