[RE-wrenches] Enphase comparison

We have installed EnPhase on two jobs in the 2-4 kW range and found that the
installation touch labor is about the same. The inverters install quickly on
ProSolar rails. You need to install the 240 VAC 2P switches on the roof, but
no big inverter on the ground. A wash IMHO.

 

They are great for mitigating the effects of shading.

To those of you who have installed PV systems in, say, the 2-4 kW range
using Enphase inverters, how would you compare the labor time and
installation materials (wire, conduit, hardware, etc.)  to a standard system
design using a single inverter?

 

Longer?  Shorter?  More or less materials?  If either, by what percentage?

 

Thanks,

Marco
