Operating the Powerwall for 6.5 kilowatt hours the next day, saves $0.98 of electricity charges. Factoring in the charging costs, saves $0.53 a day of electricity costs, or $193 a year, requiring a payback period of 38 years, which is almost 4 times the warranty period of 10 years for the Powerwall. If solar power was used to charge the Powerwall, it would save the charging fee of $0.45 a day, making the Powerwall savings each year $358. Factoring in the installed solar panel cost of $3,570[2] for a 1.5 kilowatt system[iii], makes the payback period 31 years, still 3 times the warranty period.
