[RE-wrenches] String Vs Micro

[Jesse Dahl]

A lot of my initial meetings with customers go like this: budget, array location, "how do I know if one module stops working", they have read in articles about micros module level data and really want it. 

That's what I see as the driving factor here.  Our winter temps keep them out of the market however.
