Has anyone had experience with a solar battery?

14. Well, that can be a touchy point with some folks

especially utilities. My view, and just my opinion, is to go grid tied. My reasons are:

1) The grid is your backup

2) Your excess power gets used by your neighbors (though the utility company gets the money in most places). Otherwise once you charge your battery, and power your house, any excess power is wasted.

That a caveat:

Unless you have a battery backup, properly installed with a transfer switch, the loss of grid power means you lose power as well, even during the day, because safety rules require your array to shut down, to prevent "backflow" onto the lines. IF a tree takes down a power line, the linesmen do not want your array feeding power back into a line they are working on.

Of course, if you are not tied to the grid, then no worries. BUT, you must have a backup power supply (generator or battery) to power your house at night and during overcast days.
