But.... this is why the systems are grid-tied!  While you may not be using 
that surplus power in the middle of the day, someone else at home is using 
that power for their air-conditioning.  And... when you're not producing 
enough power, there's always the grid for you to suck power from.

I would be interested in your reasoning there.  Domestically generated 
power from solar *should* reduce greenhouse gas emissions, and the more 
widespread the better.  Whether it's the best use of that money is another
