JA Solar are one of the largest of the Chinese manufacturers.

Solar wholesalers in WA are offering 440W, black framed 'N' type JA 440W mono glass panels.
They also have 550W and 565W silver-framed models intended for commercial installations.

The price for the JA 440W is at time of writing $6 more per panel than an equivalent Risen, and $3.5 more than a JinKo.
