As RossW said.. you simply cannot group them into "Chinese". Be like grouping into you like "cars"? . Too many manufacturers, to many companies using the manufacturers. Just because it is made in China, doesn't mean much other than a firm wanted a product made there to lower labor cost. A lot of firms out source the fabrication to Chinese companies , and those Chinese companies must use the firm's specs (or basically be in breach of contract, lose business , etc) .
I have no where near what Ross has , but I have about 500 W (5 x 100W) of Chinese made panels, that use Q cells, and I'm happy with both the panels and the cells. I started with one, looked at the quality, power output, and etc and went on from there. These are also not the cheapest panels.. I put them in the "moderate" range.
Now does that mean I would just buy any panel that said made in China... course not. That applies to any country and any product.. do the research on exactly what you (want) to buy.
