westinghouse solar on cost reductions in usa

I am amazed at what the Americans think is reasonable cost and labour to install PV in the US - 6hours/kWp installed! the next idea of going to Bunnings and getting a plug-n-play PV in a box to be installed by Harry the Happy Householder is just scary.

Interesting insights into possible cost reductions possible for Westinghouse string inverters in the USA

After talking with Barry about their continued efforts to simplify solar, I realized an interesting point. Isn’t the goal of the solar PV industry to be to not NEED solar financiers? Like Solyndra. Reduce the costs of solar so much that most homeowners will not need financing.
Westinghouse’s best customers are completely new to solar. They’ll never need to learn string sizing, temperature coefficients, and residential solar will become extremely simple.
Barry said that AC modules are seeing a 50% direct labor reduction compared to industry norms. They’re seeing around 6 to 7 man hours per kW on residential installations compared with the industry average 10 to 11 hours per kW
