Solar Net Metering Credit Not Showing on Bill? Here's Why and How to Fix It

What net metering credits should look like on your bill

When your rooftop solar system exports electricity to the grid, your utility should credit those kilowatt-hours against your consumption at an agreed rate. This typically appears as a 'Net Energy Metering Credit,' 'NEM Credit,' or 'Export Credit' line item. The credit either reduces your balance to zero for that month or carries forward as a banked credit to future bills.

• NEM credits should appear on the bill covering the period when solar was exported
• The credit rate should match your interconnection agreement — not necessarily the retail rate
• Annual true-up (common in California) settles the running credit balance once per year

Most common reasons NEM credits go missing

There are several distinct failure modes. The most frequent are: the utility's billing system not linking your solar meter to your main account after interconnection; the export register on your smart meter not being read during estimated billing periods; your NEM tariff expiring or being changed without notification; or credits being applied to a legacy account number rather than your current one.

Step 1: Get your solar inverter or monitoring data

Your solar inverter or monitoring app (SolarEdge, Enphase, etc.) records how much energy your system generated and, in most cases, how much was exported to the grid. Download a monthly export report for the billing period in question. This is your primary evidence.

• Check inverter monitoring for total generation and self-consumption figures
• Export = generation minus self-consumption — this is what should be credited
• Screenshot and save this data before contacting your utility

Step 2: Compare exported kWh against bill credits

Multiply your exported kWh by the export rate in your interconnection agreement. Compare this against the NEM credit on your bill. If the credit is absent, smaller than expected, or applied at a different rate, you have a documentable billing error.

Step 3: Contact your utility and request a billing correction

Call the NEM or solar billing department specifically — general customer service agents often cannot resolve interconnection-related billing issues. Provide your inverter export data, your interconnection agreement rate, and the expected credit calculation. Request retroactive correction going back to when the error began.

• Ask for the solar/NEM billing specialist, not general customer service
• Reference your interconnection agreement number in the dispute
• Request corrections for all affected billing periods, not just the current month

Step 4: Escalate if unresolved

If the utility does not correct the credits within 30 days, file a complaint with your state public utility commission. In California, this is the CPUC. In most states, the commission has authority to order retroactive credit corrections. Include your inverter data, the expected credit calculation, and your correspondence with the utility.
