Why "plug 'n Play" Solar?

The key differentiation between traditional solar power and Plug 'n Play solar,
. . . is the output voltage.

The Plug 'n Play solar has an output voltage of 120V AC,
. . . while the traditional solar installations have 240V AC,
. . . (which requires a licensed electrician to make the connection)

When all components of a Plug 'n Play solar are UL certified,
. . . then Utilities approve them.

And as stated by the Dept. of Energy, there is a,
. . . 50% Cost Saving if solar energy becomes Plug 'n Play.
This effort is part of the Department’s broader strategy,
. . . to spur solar power deployment by reducing non-hardware,
. . . or “soft” costs, such as installation, permitting, and interconnection,
. . . which currently amount to more than
. . . 1/2 of the total cost of residential systems.
