First electricity bill after solar rebate

Oh I forgot to mention I got my first electricity bill after having the solar panels installed and the meter in place.  My electricity bill was $18.57!  Now the interesting thing was that it was all from late fees... because I forgot to pay my last electricity bill on time.  Solar rebate got me back $409.67 (602kWh @ 68c).  And we used 2091kWh.  So that was really good!
