August:

What about the expense of servicing and/or replacing roof mounted inverters?  There is a very finite limit on the weight that is practical/legal to haul up a ladder. Sure it's easy to toss an inverter on the roof at the install when there is already a lift in the budget to hoist the PV.  Later on your crew might be tempted to slide a replacement inverter up the ladder, but this is not always safe or OSHA legal.

It's at least $400 to bring a scissors lift and a reach lift is about $600. Is this really good economics / safety practice?
