The smart guys here will need some more information. You use 27.6kWh per day going off your bill. 911kWh/33 days. Roughly 1kWh every hour so that bank would last you 4.92 hours with nothing charging it.
Things like how much of your bill do you want to offset, are you still going to be grid tied, how much room for panels, and a general location are needed. I am sure there is more, but I am pretty new to this too.
