How this Austin solar cost calculator works
This calculator sizes a solar system from your electricity use. Your monthly bill, divided by the average Texas electricity price, gives your yearly use; Texas's sunshine (1,421 kWh per kW of panels a year) then gives the system size that covers it, adjusted for roof direction and shade. The installed price is that size multiplied by the price per watt homeowners in Texas pay installers. Payback compares that price with what the panels save at Texas power prices, assuming prices rise 3% a year.
Texas numbers this calculator uses
- Installed price
- $1.91–$2.59 per watt in Texas (typical $2.25), before rebates. A typical 6 kW home system costs $11,500–$15,500.
- Sunshine
- 1,421 kWh of electricity per kW of panels a year in Texas.
- Electricity price
- About 16.1¢ per kWh, the average residential price in Texas.
- Selling power back
- There is no statewide net metering rule; what you are paid for exported power depends on your utility or retail plan.
- Rebates and tax credits
- The 30% federal tax credit for buying solar ended for systems installed after December 31, 2025. Leases and power purchase agreements can still carry a federal credit through the installer for systems in service by the end of 2027.
An estimate, not a quote. Roof size and pitch, shading, equipment, permits and the installer all change the final price; installers confirm it after a site visit.
