SolarCity adds Tesla battery to its new solar-plus-storage home product | Utility Dive

“The Tesla 7 kWh battery costs $7,000 installed and is meant to be cycled daily,” Tucson Electric Power’s Carmine Tilghman recently told Utility Dive. “At the average all-in electricity rate of $0.12 per kWh, the buyer saves $0.84 per day. And $7,000 divided by $0.84 per day means it will take 8,333 days or about 22.9 years to get the initial investment back for a battery that comes with a ten year warranty.”
