One SREC sold for April, for $ 640.00.

I'm just doing 'back of the envelope' calculations, but it appears that our system is halfway to paying for itself. (Disclaimer: we were lucky enough to catch the tail end of the New Jersey rebate program and also received a substantial federal tax credit.) When we installed I estimated the payback period as 4.5 years. Looks like it'll be more like 5.1 years. I can live with that...
