Identify the actual settlement cycle before comparing balances
When an annual solar true-up differs from a saved monthly credit, first identify the actual program, account and complete settlement period. Reconcile the opening balance, monthly charges and credits, annual adjustments and next-cycle treatment. An accumulated export credit is not necessarily the same amount or calculation as net-surplus compensation, and a lower annual figure does not by itself prove a failing solar system.
PG&E’s NEM explanation and the California Public Utilities Commission’s comparison of NEM and net billing provide the specific examples used here. Their scope is not every utility, tariff or community-choice arrangement. No customer account, complete applicable tariff or sample bill was evaluated for this guide, so no amount, credit eligibility or case-specific payment outcome is established.
Recover the account’s program and real annual window
Obtain the full annual statement, the monthly records within its actual cycle, account and meter identity, program enrollment and rate-plan information. Ask the utility which opening and closing dates define the settlement. Do not automatically substitute January through December, the app’s lifetime total or the months visible in one screenshot for the period actually being settled.
Record any move, meter change, account correction, program change or separate energy supplier during that window. Ask the relevant organization how those events were treated. Keep actual documents and unanswered questions rather than guess that a new tariff applies because a neighbor recently installed solar. The statement’s annual label does not identify every governing account condition.
Distinguish monthly payment from the running solar ledger
A statement can show an amount currently due and a separate year-to-date solar balance. PG&E describes monthly NEM statements and an annual true-up statement with the cycle’s final balance. Read each figure according to its actual purpose. A credit in a running summary should not be treated as permission to ignore another charge or as a check already owed.
CPUC’s comparison also distinguishes NEM annual billing and true-up from net-billing monthly payment with an annual credit true-up. Do not transfer the payment schedule of one arrangement to another. Ask the utility to explain the actual current amount due and settlement entries. This guide does not advise withholding payment or assume a billing inquiry suspends a deadline.
Build an annual reconciliation, not a sunny-month comparison
Create a simple record of these entries using the actual statement descriptions. If a month or adjustment explanation is missing, label it missing. Do not silently fill it with an app estimate. A complete ledger gives support a specific question to answer and separates an accounting discrepancy from an equipment-performance complaint. It does not recreate a tariff calculation without the applicable inputs.
| Item | Evidence to match | Common mismatch |
|---|---|---|
| Opening balance | Start of actual settlement cycle | Beginning of calendar year |
| Monthly charges and credits | Every complete statement in the cycle | Selected favorable screenshot |
| Adjustments | Utility explanation and affected period | Assumed current production problem |
| Annual surplus calculation | Actual program and settlement basis | Accumulated retail export credit |
| Separate supplier entries | Applicable generation and delivery records | One provider assumed to handle both |
| Next-cycle treatment | Utility response and following statement | Assumed credit disappearance or cash payout |
Ask which credits are being carried and which surplus is settled
CPUC distinguishes the basis of credits for exports before true-up from net-surplus compensation at true-up. PG&E likewise describes surplus compensation on the annual NEM statement. Ask which entry your concern actually involves, what period it covers and what account-specific calculation the utility used. A saved credit amount and the eventual surplus figure need not represent the same entitlement.
Request the explanation of any carryover, settlement, reset or pending adjustment under the actual tariff. Do not assume every accumulated credit is paid in cash, every remaining balance carries indefinitely or every program treats the next period identically. The reviewed pages contain differing example rate ranges, and current applicable rate documents were not fully examined; this guide intentionally supplies no cents-per-kilowatt-hour calculation.
Keep production and utility-meter evidence in their proper roles
The production-versus-bill guide explains why behind-the-meter solar generation is not identical to grid exports. Use its separate channel discussion when necessary, but center this review on the full annual credit lifecycle. A high production total in a selected app month does not reconstruct the annual utility ledger.
If support needs interval data, ask for the actual import and export records for the matching cycle, with known gaps and time conventions retained. Use existing supported exports rather than move sensors, alter a meter or experiment with battery settings. Electrical inspection belongs with qualified personnel only when the evidence establishes a relevant technical question; an unexplained annual balance alone does not justify replacement hardware.
Identify who handles each portion when another supplier is involved
If a community-choice or separate energy supplier appears on the account, ask which organization handles the questioned generation charge, export credit or settlement, and what period its statement uses. Do not assume that a utility’s delivery record alone reconciles every supplier entry. Keep the actual provider responses and case references separately, with the disputed line identified.
No community-choice tariff or account was reviewed here, so this article does not describe a universal supplier payout method. It also does not concern an offsite community-solar subscription or renewable-energy-certificate ownership. Those arrangements involve different evidence. A rooftop owner should identify the actual billed service before choosing which record trail to investigate.
Request a specific explanation and preserve the correction trail
Provide the utility the complete cycle, account identity through its secure route, questioned entries and missing explanations. Ask which tariff and data support the calculation, how annual surplus differs from prior export credits, and what will appear at the next cycle’s opening. Retain the case reference and written response rather than accept an unrelated generic solar brochure as the calculation for this account.
If a correction is made, keep the original statement, corrected record, affected dates and explanation together. Verify the actual adjustment on the account or later statement identified by support. If the response only explains an existing charge, record that outcome accurately rather than mark it refunded. The solar records guide helps keep technical history alongside, but distinct from, the billing evidence.
Illustrative scenario: a monthly screenshot becomes a payout expectation
Imagine an owner saves a favorable monthly credit screenshot and expects that number as a payment at annual settlement. This is an illustrative scenario, not a bill we audited. The owner identifies the actual solar program, collects the full cycle and asks support to explain the annual calculation and next-period treatment rather than assume credits were lost.
The utility’s actual response is compared with the relevant statement entries, while any genuine missing-data or performance question stays on its separate track. Nobody buys a battery, changes metering or stops paying a bill to fix a guessed cause. The example promises no credit amount, error finding or payout; it shows how to replace an expectation based on one month with a complete-period question.
Frequently asked questions
Is annual true-up always January through December? Confirm the actual cycle.
Is an export-credit screenshot the eventual surplus payment? Not necessarily; identify the calculation.
Do NEM and net billing always have identical monthly payment duties? CPUC distinguishes them in its specific comparison.
Does a smaller annual credit prove failing panels? No.
Does this supply the applicable tariff or payout rate? No; obtain actual utility evidence.
