EIA Table 5.6.A, June 2026 residential column; published August 26, 2026. Divide the published cents/kWh by 100. This preliminary statewide average is a fallback, not your utility tariff. Use your bill's energy-only rate; fixed charges remain payable.
A statewide residential average is a consistent early-planning input, not a reproduction of one utility bill. SolarCalcNow uses it to value electricity consumed directly from the solar system and to establish the annual energy-charge ceiling in the savings model. The calculation does not assume solar removes fixed charges, minimum bills, demand charges, taxes, or every time-of-use period. It also values exported production separately under the selected export assumption. This separation lets you test the effect of a different rate or export value without changing the system's physical production target.
Texas households can face materially different retail-plan structures even when the statewide residential average is the same planning reference. The rate on a bill may depend on the selected provider, contract terms, usage band, delivery charges, and time period. For that reason, use the state figure to compare broad scenarios, then replace it with account-level evidence before treating savings as project-specific.
Strong solar production does not by itself establish attractive payback. A proposal also needs a realistic export value and a clear explanation of how imported and exported electricity are settled under the household's plan. Compare the written plan and recent bills with the calculator assumptions, and do not interpret a statewide average as a verified buyback rate or a promise about future retail prices.
These values come from the existing calculator engine. They multiply the annualized usage scenario by the source-linked state rate and do not include fixed charges, future rate increases, or a utility-specific tariff.
| Monthly usage | Annual usage | Modeled energy charge |
|---|---|---|
| 600 kWh | 7,200 kWh | $1,148 |
| 900 kWh | 10,800 kWh | $1,722 |
| 1,200 kWh | 14,400 kWh | $2,295 |
The calculator estimates bill savings from self-consumed solar at the selected residential rate. A higher rate can shorten payback, while a lower rate makes installed cost and export credit assumptions more important.
Utility plans, time-of-use pricing, net billing, fixed charges, and export credits can differ from a statewide average. Check your bill and utility tariff before treating a planning estimate as a quote.
