Many factors go into the potential savings including system size, how much electricity you use and what time of day you use it, the overall efficiency of your system, panel location, shading issues and more. But as a general example, households using around 1300 kWh a month installing a 9-kW system might expect about a 40% reduction in the total cost of electricity.
Please read this part carefully: If a salesperson is claiming that you will no longer have an electric bill or claiming with certainty that you will experience a guaranteed reduction (i.e. “you will save 70% on your bill every month!”) it is most likely untrue.
