It is a good premise. I hope the model works. This is a great (looking) idea for places like cities where space is so limited but there is so much rooftop for
solar collection. I am a big fan of wind power but it is situational since we are looking at the south shore of lake superior and a $5000 windmill and $1000 of batteries will run your home pretty much in perpetuity. Winds are constant due to the heat-sink effect of the lake.
