Net metering / billing
Net Billing (RCP)

Texas has no statewide net metering; deregulated-market (ERCOT) homeowners choose a retail electric provider's solar buyback plan. This estimate assumes enrollment in a buyback plan and models a conservative ~$0.075/kWh export credit — some providers offer little or no export credit, in which case savings come only from self-consumption and are lower. Compare buyback plans and verify export terms before switching.

Estimates use the average Texas current utility rate (before solar) of $0.16/kWh (EIA, retrieved Aug 2026) and modeled solar production; individual results vary with your rate, usage, roof orientation, and shading.
