[Shop-talk] PV system

[scott.hall at comcast.net]

yeah, I know about the loss of power at night, and I'd prefer to get the batteries.  at the time, though, I was told to get the credits you had to explicitly *not* get a battery setup.  and it was much cheaper.  I was also told I could add the batteries later if I wanted, which is what I thought I'd do after pocketing the tax credits.  I do want to pump power back into the grid (and get the check--we have net metering and the utility will pay you once a year for your surplus), but just as key was the ability to operate when the grid is down.  I figured for a lot less money, I could run a smaller generator at night for ceiling fans and the fridge.  so long as there's a/c until the sun goes down, we could get by.

of course, you apparently lose a/c (off PV only) about 4 p.m., but we have a clear exposure and a good roof pitch (I'm told), so I was hoping for better.

suppose it doesn't matter, as soon as I can add the batteries and not forfeit the tax credit, they'd be going in.  july in north florida requires a/c 24/7.  too bad they don't have hurricanes mostly during february.
