Thanks for your help. There are a number of impressive people on your list. I'd love to hear from them. I suspect that many are rather reluctant to say anything for fear of giving away any corporate know-how.
Standards are a gosh awful complicated thing.
My fear is that the standards will be developed by only the larger companies, and that the associated testing methods will be so complex and costly that the multitude of small solar companies will simply be swept away by them, since they will be unable to afford putting their instruments through the tests. This is currently the case with a number of the UL standards. To sell it in Europe, we recently had to get CE mark compliance. I know we can't wave a magic wand and make all the paperwork shrink to a single page, but I'm certain that many of the tests can be significantly simplified. This is a good thing.
