Estimate your solar economics

City-based ranges, not a quote or guarantee.

Enter an amount from 25 to 1500 dollars with up to two decimal places.
kWh

If you know your usage, enter it for a more direct consumption estimate. When usage is provided, the model uses it to estimate consumption. The electricity-value baseline remains the Texas statewide average.

Location context: Oncor delivery territory is common; retail plan terms vary by address.

Electricity baseline: 15.94¢/kWh, Texas statewide average. Your plan may differ. Sources and assumptions

Model use: Used to infer consumption when kWh is blank and to value electricity in all scenarios. Your plan may differ.

Installed-cost basis

Avoided cost

How sunlight becomes savings

Sunlight→Electricity produced
Used at homeOffsets full retail energy charge
ExportedValued at buyback / export rate
Combined electricity value determines payback

Electricity used at home and electricity exported to the grid can have different values. Your rate, export terms, and installed cost all affect payback.

In focus: Texas

Your electricity arrangement matters

Delivery: Your delivery utility operates the wires and local network.

Retail plan: Where retail choice applies, your provider sets the plan terms. Municipal and cooperative arrangements differ.

Solar exports: Check how your plan values electricity sent to the grid.

Questions worth answering

What determines solar payback?

Understand the inputs behind a payback estimate.

Which electricity costs can solar reduce?

Separate avoided electricity value from charges that may remain.

How do solar export credits work?

Check the difference between retail electricity prices and export value.

Next steps

Before you decide

  1. Check your annual electricity use.
  2. Identify fixed charges and export terms.
  3. Compare an actual installed price with the modeled cost.
  4. Check roof, financing, maintenance, and insurance factors.
