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. - Peter Peter T.

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