TECO Solar in Tampa: Net Metering, Solar Batteries and What Homeowners Need to Know

By iContracting Solar Team · 2026-09-29

The short answer

Tampa Electric, commonly called TECO, uses a bidirectional net meter after an eligible solar system is installed and approved. Excess solar is credited based on the retail energy rate, and negative net usage carries to the next month. TECO says interconnection approval can take up to 30 calendar days after it receives a complete application.

Solar and batteries do not receive identical treatment. Batteries must be interconnected, but they are not net metered. TECO also uses separate applications for solar, battery-only and combined solar-plus-battery projects.

Begin with the correct TECO application

The interconnection process starts before a system is allowed to operate with the grid. The equipment in the proposal determines which application is appropriate. TECO provides separate paths for:

• A solar installation without a battery.
• A battery connected without a new solar installation.
• A combined solar and battery installation.

Using the correct application helps TECO review the actual configuration. A homeowner should not assume that a solar application automatically covers a battery added to the project. Ask the installer to identify the application being submitted and keep a copy of the complete package.

Current forms and instructions are available on TECO's official Connecting Your Solar page.

Step 1: Design and certified installation

The system should be designed around the property's electricity use, usable roof area and equipment goals. If backup is part of the plan, the battery and electrical configuration need to be included from the beginning so the combined application reflects the intended system.

After a certified installation, TECO installs a bidirectional net meter. That meter tracks electricity moving from the grid to the property and excess solar moving from the property to the grid. The meter is the basis for net metering credits.

Before signing, ask which system tier applies. TECO's Tier 1 agreement covers systems of 10 kilowatts or less, a category that includes many residential projects. A larger project should be discussed with TECO under the applicable requirements rather than assumed to use Tier 1.

Step 2: Submit a complete application

TECO's stated review window is tied to receipt of a complete application. Approval can take up to 30 calendar days after TECO receives that complete package. The distinction matters: missing information can prevent the review period from beginning as expected.

The installer should be able to explain what has been submitted and whether TECO has requested anything else. Homeowners can keep the project realistic by allowing for utility review instead of treating approval as immediate.

For net metering questions, TECO lists NetMeters@tecoenergy.com and 813-275-3909. Contact TECO directly if the application status, required agreement or equipment treatment is unclear.

Step 3: Approval and bidirectional meter

Once the certified system and complete application satisfy TECO's requirements, TECO installs the bidirectional meter needed for net metering. The system should not be represented as fully interconnected before the required utility steps are complete.

The meter records imported and exported electricity separately. Solar first serves electricity needs at the property as production and usage occur. When production exceeds use, the extra power can flow to the grid and be measured as an export.

How TECO credits excess solar

TECO credits excess energy based on the retail energy rate. If the account reaches negative net usage, that balance carries to the next month. This monthly carryforward helps address the natural mismatch between solar production and household use across billing periods.

The statewide investor-owned utility framework also provides that unused credits at the end of the calendar year are paid at avoided cost. Fixed monthly customer charges still apply. Our broader guide explains how Florida net metering works, including why the year-end treatment makes system sizing important.

A proposal should not treat every exported unit as though it will have the same value forever. It should show how much electricity the property actually uses and avoid using oversizing as a substitute for careful design.

The Energy Planner requirement

TECO customers on the Energy Planner rate must switch to the standard residential rate if they receive a net meter. This is a specific program requirement and should be identified early, not after installation.

A customer using Energy Planner should ask how the switch affects the bill structure before evaluating the solar proposal. The correct comparison uses the standard residential arrangement that will apply with the net meter, not an old rate plan that the customer cannot keep.

Check the change directly with TECO. An installer can help prepare interconnection documents, but TECO is the source for the current account and rate requirements.

Battery interconnection is not battery net metering

TECO requires batteries to be interconnected, but batteries are not net metered. This distinction prevents a common misunderstanding. The battery may be part of a utility-approved configuration, yet that does not mean battery exports receive solar net metering credits.

The reason to consider storage should therefore be tied to the homeowner's goals. A battery can store energy for later on-site use and, with the right backup equipment, can help power selected loads during an outage. Its role should not be described as earning TECO net metering credit.

Battery-only and solar-plus-battery projects have separate applications. Confirm the intended operating mode, equipment and application with TECO and the installer. Read what happens to solar during a power outage before deciding whether essential-load or broader backup fits the property.

Rooftop solar or Sun Select

TECO's Sun Select is a shared or community solar subscription. TECO owns the panels, and the program is available to renters and owners. It offers an alternative for someone who wants a solar option without putting panels on the property.

Rooftop solar and Sun Select are different arrangements. A rooftop customer owns or otherwise contracts for equipment at the property and follows the applicable interconnection process. A Sun Select subscriber participates in a utility-owned solar program without a rooftop installation.

The better fit depends on the customer's circumstances and goals. Renters, properties with unsuitable roofs and owners who do not want on-site equipment may want to ask TECO about Sun Select. Do not rely on an old price or term; check the current subscription details with TECO.

Roof and storm planning still matter

Utility approval is only one part of a good project. The roof should be evaluated before panels are installed. If it is aging or damaged, read whether to replace a Florida roof before installing solar. Coordinating roof and solar work can avoid removing and reinstalling panels later.

Tampa-area homes also need a realistic storm plan. A grid-tied system without backup shuts down when the grid goes out. Review solar panels during a Florida hurricane for preparation and safe post-storm checks.

A practical TECO checklist

Before signing, confirm that Tampa Electric is the utility on the bill. Ask whether the project is solar-only, battery-only or combined, and identify the matching application. Confirm whether the system is Tier 1 at 10 kilowatts or less. Make sure the installer plans around the stated review period of up to 30 calendar days after a complete application.

If the account uses Energy Planner, discuss the required move to the standard residential rate. If a battery is included, make sure the proposal does not describe it as net metered. Ask which loads the battery is intended to support and avoid accepting a guaranteed outage runtime without a property-specific assessment.

Use TECO's official page, email or phone number for current requirements. Then compare the project with our OUC solar guide, Duke Energy solar guide or Florida incentives guide only when those topics are relevant.
