Looks like you did really well over the summer months. Your virtual power station plan appears better than what we have here. I am still waiting for a full quarterly bill to see if the one I am with is any good. I have heard of these small plug set ups for people who rent but I have not seen any out here yet.
I am hoping we will see a big boom in solar in the next few years. I track mine to see how I am doing, but it will be a few years before it pays for itself. That should be quicker in Australia though.
