He said that whenever he mentions this to a solar outfit - running a 150 hp motor on pv - they look back at him like a deer in the headlights. Can you meet his challenge?

No rural water pumping PV designer that I know works with motor loads of such scale. Indeed, it makes my head spin to think of it.

These are the folks who regulate our three private utilities and 20 +/- rural co-ops, and he is perhaps the most conservative one of the five. Last fall he initiated an ill-conceived regulation to cut in half our state's RPS and pushed it through to passage on the PRC; about two months later the ruling was rescinded due to a huge public outcry. So if it were even possible to address his particular request, the potential consequences could have far-reaching effects politically.
