Seeing different numbers in your solar app and electric bill? For Florida homeowners, that is often a billing or accounting difference, not a sign that the system is underperforming.
Your app may show total solar production, while your utility bill reflects only energy exported after your home used some electricity. Other common reasons include:
• Billing dates that do not match the calendar month
• Estimated versus actual meter reads
• Meter-reading or data-reporting delays
• Export credits calculated and posted on a later statement
• Different program structures, such as net metering or net billing/avoided-cost arrangements
Homeowner checklist:
1) Compare the same billing-period start and end dates, not just the same month name.
2) Separate total production from exported kWh.
3) Check whether the meter read is estimated or actual.
4) Look for pending credits that may appear on the next bill.
5) Confirm the current tariff and credit calculation with your utility.
Duke Energy Florida and TECO have different programs, tariffs, credit values, and billing formats. Duke customers should verify details directly with Duke; TECO customers should verify them directly with TECO. A qualified solar professional can also help reconcile the app, meter data, and bill before you assume there is a system problem.
