Solar Buyback Programs: How to Read an Export-Credit Offer
Learn what solar buyback programs pay for, why export credits vary, and the questions to ask a utility or retail provider before sizing a system.
Quick answer
A solar buyback offer describes how exported electricity is credited under a particular program or tariff. It should be evaluated separately from the retail electricity price and can change by provider, territory, or contract.
Import and export are different transactions
Your utility can charge one rate for electricity you buy and credit a different value for electricity you export. A solar estimate should state both assumptions rather than use one blended rate.
Read limits and timing
Some programs have enrollment deadlines, caps, rollover rules, eligibility requirements, or credit-expiration terms. Review current provider materials for the exact offer attached to your account.
System size can change the result
When exports are worth less than on-site use, oversizing can weaken economics. Compare annual production, daytime load, battery cost, and export rules before selecting capacity.
Keep a copy of the program terms
Save the tariff, enrollment confirmation, and interconnection documents. They are more reliable than a sales claim if billing questions arise later.
