TECO net metering explained: how Tampa Electric credits your solar
Net metering is the quiet piece that makes home solar pay off in Hillsborough County, and most people have never had it explained plainly. If you are going solar in Riverview or anywhere in Tampa Electric territory, it is worth understanding, because it shapes how big your system should be and how close to a zero-dollar bill you can get.
What net metering is
Your solar panels make the most power in the middle of the day, which is often more than your home is using at that moment. Net metering lets that extra power flow back onto the TECO grid, and your meter effectively runs backward, banking a credit. Later, at night or on a cloudy day when your panels are not covering your use, you draw that credit back down. In short, the grid acts like a battery for your billing.
How TECO handles the credits
Under Florida's net-metering rules, Tampa Electric nets your production against your usage each month. If you produce more than you use in a month, the extra kilowatt-hours carry forward as a credit against future months, valued at the retail rate. Once a year there is a true-up, where any leftover credit you never used is settled at a lower wholesale rate rather than the full retail rate. Terms can change, so we confirm the current TECO program when we design your system, but that monthly-credit, annual-true-up structure is the shape of it.
Why it matters for your bill
Net metering is what turns a sunny afternoon into savings you actually use after dark. Without it, the power you overproduce would simply be lost. With it, a system sized correctly against your usage can bring your electric bill close to just the fixed monthly connection charge. That is the difference between solar that dents your bill and solar that nearly erases it.
Why we do not just build the biggest system
Here is the honest part a lot of installers skip. Because leftover credits at the annual true-up are paid at that lower wholesale rate, building a system far larger than your yearly usage does not pay you back well for the excess. The sweet spot is sizing your array to your actual TECO usage, not overselling you panels you will never get full value from. That is exactly how we design, and it is why we start from your real bill.
Where battery fits in
People sometimes mix up net metering and battery backup. They solve different problems. Net metering is about economics, using the grid to bank your daytime surplus. A battery is about resilience, keeping your home powered when the grid goes down, since a standard grid-tied system shuts off in an outage. Many Hillsborough homeowners do both: net metering for the everyday savings, and an Enphase battery for storm season.
The bottom line
