I'm going out on a limb and guessing you mean in mid-winter in south TX.
We are peaceful people, no hanging tonight :)
What he needs is a calculator like this
Click on the closest town in Texas. Enter 1 KW panel size (the calculator is for large home system, it won';t accept less than 0.5 KW value). Enter "fixed tilt" and either 0 degrees for flat or whatever the value is for a latitude tilt, or Lat+15 or Lat+20 for winter, or Lat-15 for summer. Compare the results for those months that yo are interested in. They will be in daily KWH/sq.m or monthly KWH, not AH that we normally use in RV, but this doesn't matter. He wants to know how much more the tilt will get him, so this is what it will.
BFL will sure chime in and say that all the science is cr-ap and only his measurements are the truth :) but for a very rough estimate I think this calculator should be given a chance.
And there are other data, statistical averages for 30 years of observation, including Texas among other places, but I won't mention those for the same reason as before.
