If you're interested in some real world napkin math data points. I live off grid in the bay area and on the worst case rainy day around the solstice I made about 2/3 of the wattage of my solar array in watt hours. That day was in the worst week and I made about 7x the wattage of my solar array in watt hours over the course of the week. LiFePo4 storage cost me about $3/Wh including BMS, solar cost me about $0.7/W including charge controller.
