THE SHORT ANSWER
FPL states that electricity produced and consumed inside the home does not pass through its meter. The FPL bill therefore cannot show the array’s total production; that measurement normally comes from the inverter or monitoring system. [1]
Draw the measurement boundary
Solar can supply household loads, export surplus energy or charge compatible storage. FPL measures what crosses between the premises and grid. The inverter reports solar production, while a separate site meter may estimate home and grid flows. Label each source before comparing numbers that answer different questions.
Use aligned dates and units
Download the utility billing period and the monitoring totals for the same start and end dates. Keep kilowatts, which describe power at a moment, separate from kilowatt-hours, which describe energy over time. A midday screenshot cannot be reconciled with a monthly bill total.
Reconstruct a simple energy balance
For a home without battery complications, reported solar production is divided between energy used on site and energy exported. Utility-delivered energy covers consumption not supplied by solar. The figures may not match perfectly because clocks, intervals and measurement points differ, but the structure shows why delivered minus received is not total household use.
Treat missing data as a monitoring issue first
If the inverter app has a gap while FPL continues billing, record whether production is absent, home usage is missing or the whole site is offline. An internet or account-access problem can hide data without stopping generation. Do not order replacement panels from a utility bill alone.
Build a service-ready packet
Provide two consecutive bills, a monitoring export or screenshots, the inverter model and the date the mismatch began. Origin can use that packet to define a maintenance review. Billing corrections remain with FPL; equipment diagnosis requires system evidence rather than treating the utility meter as a rooftop production meter.
Before your next conversation
- Align utility and monitoring date ranges.
- Compare kWh totals, not a momentary kW value.
- Identify which measurement stream is missing.
