Net metering in Indiana lets a home with solar panels send surplus electricity to the grid and receive credit against the power it draws later. This guide explains how Indiana’s rules apply to a typical homeowner, how credits are calculated on your bill, what paperwork and equipment you need, and where people most often go wrong. By the end, you should know what to ask your utility and how to check that your credits are being applied correctly.
What Net Metering Means for an Indiana Homeowner
Under net metering, your solar system first supplies the electricity your home is using at that moment. Any extra power flows out to the grid through your meter. When your panels are producing less than you need, such as at night or on cloudy days, you draw from the grid as usual. The meter tracks both directions, and your utility bills you for the net difference over the billing period.
Indiana has long been one of the states where the specific terms depend heavily on which utility serves your home. Indiana’s major investor-owned utilities each run their own solar tariff, and the details, including how exported energy is valued and how long credits roll forward, can differ between them. Before you size a system, confirm which utility territory your address falls in and read that utility’s current interconnection and net metering language.

Step-by-Step: Getting Enrolled in Net Metering
The process is largely the same across Indiana utilities, even when the rates differ. Work through these stages in order.
- Confirm your utility and service territory. Your electric bill names the provider. Check that the utility allows residential net metering and what system size cap applies to your account.
- Size your system to your usage. Pull 12 months of kilowatt-hour usage from your bills. Most homeowners aim for an annual production that roughly matches or modestly trails consumption, since exported energy may be credited at a lower value than the energy you consume.
- Request an interconnection application. Submit it before you install. Utilities generally require approval before a system is switched on, and some review the design before work begins.
- Install the system with a licensed installer. Installers typically handle the electrical permit and inspection. Ask whether the inspection is completed before the utility is notified.
- Get the bidirectional meter installed. Many utilities swap or program your existing meter so it records both imports and exports. Confirm the meter change date with the utility.
- Receive permission to operate. Do not energize the system until the utility sends written authorization. Operating early can lead to delays or penalties.
- Verify your first bill. Check that the export line appears and that credits carry forward as the tariff describes.
How Credits Are Calculated on Your Bill
Your bill compares two numbers: energy you pull from the grid and energy you send back. The net figure determines your charge. If you export more than you import in a month, you usually carry a credit forward rather than receiving cash, and how that credit is handled at the end of a 12-month period depends on the utility’s tariff. Fixed monthly service charges are typically charged regardless of credits. For another angle, check out Net Metering Solar Inverter: How It Works and How to Size One.
A simple example helps. Suppose a home imports 700 kWh in a billing period and exports 450 kWh. The net import is 250 kWh, which is the amount billed at the applicable rate, plus any fixed charges. In a sunnier month, the same home might export more than it imports and roll a surplus into the next bill.
Factors That Change Your Credit Value
| Factor | Why It Matters |
|---|---|
| Utility tariff structure | Determines whether exports are valued at retail rate, avoided cost or another formula. |
| Time-of-use rates | If you are on time-based pricing, the hour you export can change the value of that energy. |
| System orientation and shading | Affects annual production, which determines how much surplus you generate. |
| Home usage pattern | Households that use power during daylight hours often consume more of their own production directly. |
| Carryover rules | Affects whether unused credits expire, roll over or are paid out at the end of the year. |
Checking Your Meter Reads
Ask your utility how it records exports and whether you can see interval data online. Compare a few billing cycles against your inverter’s production log. Small differences are normal, but a large gap usually means a meter misread or an incorrect tariff setting.
Common Mistakes Indiana Homeowners Make
- Sizing the system from a sales estimate alone. Use your own bills and an independent production estimate instead.
- Energizing before approval. Wait for written permission to operate.
- Ignoring the tariff year. Check whether unused credits are paid, carried forward or lost at year end.
- Forgetting to update the utility after changes. Adding panels or a battery may require a new application.
- Assuming a high bill means the system is broken. Fixed charges, seasonal heating or cooling loads, and a larger than expected net import can all raise a bill even with working solar. Compare kWh figures rather than dollar totals.
Tips for Getting the Most From Net Metering
- Shift large loads such as laundry, dishwashing and EV charging to daylight hours when your system is producing.
- If your utility offers time-of-use pricing, model whether that plan or a standard plan gives you more value for your exports.
- Keep a simple spreadsheet of monthly imports, exports and net charges for the first year.
- Read your utility’s terms for system size limits before buying equipment, since caps can change.
- Consult a licensed electrician or your installer before modifying your electrical panel or service.
Recommended gear
A few inexpensive tools make it easier to verify what your meter and inverter are reporting.
- Clamp-on power meter: Lets you measure real-time load on individual circuits so you can compare household use against solar output. View on Amazon
- Smart plug with energy monitoring: Useful for tracking how much a specific appliance draws during the hours your panels are producing. View on Amazon
- Multimeter: Helps with basic voltage and continuity checks on DC and AC circuits, though solar wiring work should be left to licensed professionals. View on Amazon
FAQ
Does Indiana require net metering for all utilities?
No. Indiana’s rules vary by utility and by program. Check your specific provider’s current tariff, since terms for exported energy and system caps differ.
Will my bill drop to zero with net metering?
Possibly, in some months, but not always. Fixed monthly charges usually still apply, and your net usage determines the variable portion.
What happens to extra credits at the end of the year?
This depends on your utility’s tariff. Some carry credits forward, while others settle the balance at a set point. Read the terms before you rely on a particular approach.
Do I need a special meter?
Most systems require a bidirectional meter so that imports and exports are recorded separately. The utility usually installs or configures it.
Can I add a battery to my net metering system?
Often yes, but you should notify the utility and confirm the battery is covered under your interconnection agreement. For a comparison of these options, see Solar Net Metering vs Battery: Which Should You Choose?
How long does the approval process take?
Timelines vary by utility and by how complete your application is. Submitting accurate documents and a complete design package generally reduces delays.
Should I hire a professional for the interconnection?
Yes, for most homeowners. A licensed installer and electrician can handle permits, inspections and wiring safely. Consult a professional before any work on your main service panel.
Conclusion
Net metering in Indiana works by netting the power your home exports against what it imports, with the exact credit rules set by your utility. Confirm your provider’s tariff, size your system from real usage data, and wait for written approval before switching on. Checking your bills against production data each month will tell you early whether credits are being applied the way you expect.
