They weren't talking about your total electric bill, just the "savings" of $216/mo. Regardless, it's a crock of BS. Unless the sun shines 24/7 for 365 days a year, or the rates are .45/kWh or more the entire time the sun is shining, you can't save that much with a 1.4kW system.
They may be talking about using the batteries to offset the time of use charges. Which are the most expensive rates. That's the big draw for commercial to use batteries.
