For your solar panel racking needs, we recommend IronRidge XR Rails. XR Rails are compatible with all PV modules and come in three types: XR10 (supports the least weight and requires shorter distances between support legs), XR100 (good for most residential installations), and XR1000 (supports the most weight and can have longer distances between support legs).
Follow these steps (and reference the system diagram) to ensure you get everything you need to rack and mount your solar panels:
To answer this:
For example:
The total legth of the row is 200" + 1.5" + 2" = 203.5" (16.96').
Two 17' rails would be required to mount this row of 5 modules.
All XR Rails are long enough that they must be shipped by LTL freight. Because of this, the shipping cost for a few dozen rails isn't much more than it is for just a few rails. So it's better to order one or two extra rails than to be one or two short and have to place a separate order later!
With your solar panel racking hardware picked out, it's on to mounting.
