THE SHORT ANSWER
Prepare an account-specific comparison before changing your solar system. OUC’s current page says its temporary full-retail grace period ends October 31, 2026, with billing changes beginning November 1. As of this October 14 review, that change is still ahead. [1]
Confirm which account the comparison describes
Ask OUC to confirm your export-credit category and its effective dates. Its current guidance preserves eligible older accounts’ full-retail treatment through June 30, 2045; newer accounts move to the Community Solar Energy rate through June 30, 2030, then the Retail Levelized Fuel rate. [1] Do not select a category from the age of the panels alone.
Create a cover sheet with the electric provider, service address, account holder, date of the utility response and unresolved questions. Keep full account numbers out of documents shared casually. An Orlando mailing address does not identify the electricity supplier. If a home purchase or account transfer is involved, use the separate buyer-transfer guide and obtain an answer for the incoming account. This article helps organize evidence; it cannot assign a tariff to your home.
Save the statement before the change
OUC says it will settle the solar bank before retiring it and move to monthly monetary credits, with unused credit carrying forward. [1] Save the last pre-change statement, any bank balance detail and the first affected statement. Retain the complete PDFs so a reviewer can see billing dates and adjustments together.
Use a folder with three labels: before, transition and after. Put a short note beside each document explaining what it proves. A screenshot of a balance is useful evidence of that displayed balance on that date, but it is not an explanation of how the utility calculated it. If a balance seems missing, request a transaction-level explanation before describing the change as a loss.
Build a comparison with separate columns
Use one row per statement and these columns: beginning and ending dates, billing days, imported kWh, exported kWh, credit rate shown, export credit, balance adjustment, other electric charges and non-electric charges. Mark an unavailable value as unknown. Keep monitoring production in a separate column rather than inserting it into an export field.
Then add a question column. For example: “Does this adjustment settle the earlier bank?” or “Which dates use the changed rate?” This makes the review actionable. A single total-due comparison cannot show whether a difference came from usage, billing treatment, account credits or another service. Preserve the source of each number so the same comparison can be checked without relying on memory.
Use a controlled example to understand the arithmetic
Hypothetical illustration only: hold exports at 400 kWh and compare assumed credits of $0.12 and $0.06 per kWh. Those inputs produce $48 and $24 in export credits, a $24 difference. These are invented teaching rates, not OUC rates, a forecast or an installation quote. Replace them with the account’s confirmed inputs before using the worksheet for a decision.
The example changes only one variable. Your actual next statement may also cover a different number of days, weather or occupancy. Do not multiply one unusual month by twelve and call it an annual result. Ask for a full-year comparison with consistent household assumptions and clearly identified uncertain inputs.
Keep equipment decisions separate from the first bill
A billing transition does not by itself show that more panels or a battery is appropriate. Describe the problem first: unexpected charges, unused midday production, a backup goal or a change in household consumption. Different problems require different evidence. A battery proposal should explain its operating assumptions and remaining utility charges alongside its equipment and installation scope.
If a salesperson supplies a revised projection, retain both versions and ask which input changed. Avoid accepting a new savings headline without the underlying usage and tariff assumptions. There is no guaranteed payback date in this worksheet. Its purpose is to make the next design conversation more accurate, including when the sensible next step is to resolve a utility question before purchasing equipment.
Bring a short, useful request to the review
Send the two relevant statements, the utility’s account-category response and your three most important questions. Tell Origin whether you are reviewing an existing system or planning a new design. A bill can be provided later if you prefer to begin with a callback. For a new proposal, request an account-specific comparison of the solar payment and remaining utility costs, using the same household assumptions.
Keep the original statements after the review and record who will resolve each open item. Recheck the official OUC page when the first affected statement arrives. A dated guide records what was available when reviewed; the utility’s current instructions and your actual account record remain the controlling evidence.
Before your next conversation
- Confirm the electric provider and account category.
- Save the final pre-change statement and bank detail.
- Separate exports, production, credits and other charges.
- Compare the same assumptions before changing equipment.
