Update on my solar energy system

I have been really happy with my photovoltaic system so far.

Last Oct and Nov it generated really well.  It suffered more than I had hoped during the Dec and Jan, but March has been awesome.  Today it generated 70% of the electricity I used.  Cumulative since installation it has generated 30% of my electricity.  This should increase until I turn on the AC in June.  It should be interesting to see how the summer months fair.

I did notice a couple days ago that the panels were looking a bit dusty...maybe need to rinse them.  Was hoping that was only going to be a once a year activity, but I am starting to think it will be more often.

Totally nosy, but how much did he solar system cost you to set up?

The system is a 3.8KW system. My total system cost (including installation) after rebates and tax credits was about $22K. Should be a 10 - 12 year payback.
