Solar in Round Rock: the local facts
Round Rock is served by Oncor, and sits in the deregulated Texas retail market — Oncor delivers the power, and you choose your retail provider. That matters for solar because Texas has no statewide net metering mandate. What you're paid for exported power is a feature of the plan you pick, not a guarantee. We'll show you which providers currently offer a real buyback before you commit to a system size.
Oncor does run incentive programs for solar paired with battery storage through approved participating providers. Oncor publishes eligibility rules but does not publish dollar amounts publicly — so we won't quote you a number we can't stand behind. We'll confirm what's actually available for your address and system before it goes in your proposal.
A common and expensive misconception: Round Rock is not Austin Energy. About 95.8% of the city is Oncor territory, with small slivers on City of Georgetown Utilities and Pedernales Electric Cooperative. That means the Austin Energy $4,000 solar rebate is not available to Round Rock homeowners, no matter what a door-knocker tells you.
Before you sign anything solar in 2026
Important 2026 update: the 30% federal residential clean energy credit (Section 25D) expired for systems placed in service after December 31, 2025. Any contractor still advertising “30% off from the federal government” on a cash or financed home solar purchase in 2026 is quoting a credit that no longer exists. Third-party owned structures (lease/PPA) are treated differently under Section 48E. We'll walk you through what actually applies to your situation — and we'll tell you to talk to your tax advisor before you sign anything.
