Heck, I've thought, more than once, about pullin' B+ right off the panels for a vacuum tube amplifier!
Yeah -- I guess it wouldn't work great at night.
Need
batteries.
In (some) seriousness -- I have never looked at the AC produced by our inverters*, but my guess is that it's pretty clean. Low THD.
I mean,
@amirm could
test inverters, you know? We'll get him some thick rubber gloves and rubber-soled safety boots.[/URL]
I
do know that our Honda inverter generator produces good quality AC (and its pricetag reflects that 'assurance').

* Ours - so far - is configured as a
net metering system. I.e., we make juice for our own real time use, and the excess goes back to the grid, spinning the meter backwards (so to speak). We've got about 6kW of PVs on the roof currently. Our daughter & son-in-law recently had a tracker installed to augment their PV system, and now I'm gettin' the urge to put on in, too. We have a relatively unobtrusive site in our west field that has good 'access' to clear sky and wouldn't much impact our "viewshed" nor anyone else's.
EDIT:
A partial view of the field to the west of the house.
