It gets even better:

A friend of mine did research in Germany on 1000V PV-systems. These systems=
 have their own problems; the large system voltage
can create ion migration and cause the panels to drop their performance (Po=
tential Induced Degradation). Not to mention the
safety measures than need to be taken.

Quote: "The U.S. is beginning to adopt 1000V arrays, and throughout the ind=
ustry the use of 1500V and even 2000V arrays is being
considered as a means of reducing system costs in large commercial and util=
ity-scale PV plants." (AE Solar Energy).

Interesting world we live in.

Alan,
     I didn't know that 350 was being used. That is very dangerous. But my =
references were to 12V systems and those are except as noted that the start=
le affect can get you.
Thanks,
rich!
