Solar Flow

Our first electricity bill has come in since the faulty inverter was replaced some weeks ago. Not that I am complaining. (Yes I am).  The Delta people replaced it under a 10 year warranty. Can't complain about that. If something is attached to a house, does that mean you have paid for it when you buy that house? As the previous owner actually paid the bill. Anyway we got a grand total of $15 off our bill. I have heard  a lot of  hooey about these systems and its not sparking enthusiasm so far.  I know of people who have paid $10000 to get it installed. Maybe ours will generate more over Summer. As for saving the environment all the early more generous FIT  rates will run out in the next few years and then batteries will come down in price. These batteries are huge and how are they to be disposed of?
