The average cost to install solar on a home in Texas is $3.49 per watt, with about 80 percent of systems installed for $2.87 per watt to $4.24 per watt. This is higher than the average solar cost in the West South Central Region of $3.47 per watt.
The average size of a solar system in Texas is 6.8 kilowatts, which would cost around $23,700 without any federal, state, or local incentives.
1 kilowatt of solar PV in Texas produces an average of 1,464 kilowatt-hours of electricity per year, so a 6.8 kilowatt solar system would generate 9,954 kilowatt-hours of electricity every year. An average household in Texas uses 14,116 kilowatt-hours of electricity in a year.
With an average state electricity price of 11 cents per kilowatt-hour, this solar system could save a household in Texas $1,108 each year. At this rate of annual savings, the system could pay for itself in about 21 years assuming no additional system expenses. This is less than the expected 30-year lifespan of a typical solar panel.
