It is logical to assume that Joey Klender might not have done deep due diligence on his post. Hanwha is one of the major solar cell producers in the world:
Hanwha Q CELLS
Through Hanwha Machinery they are highly capable industrial process suppliers and processors. So, a deal to supply QC on final cell production is entirely logical, but the deal is quite likely to be only the first public indication of much more extensive future plans. They are, for instance, among the world's leading heat treatment specialists, whcih can come in handy when dealing with, say, giant sized aluminum castings.
I will wager there is a far broader relationship under way.
