Where2 gave some great advice.
Solar panels have to be truck shipped so shipping under a pallet is the same price as shipping a pallet. If you have some big solar installer maybe you can buy a few panels from them. Sometimes they have someone that needs less than a pallet and add yours to the order cheaply or you can buy mixed panels.
Check out my build the first page I have some links to some well documented installs.

Sunday we will have our solar running for two years now. We have made 36.2 MWh.
We are very pleased.
A solar install in TX should do very well.
Check out PVwatts if you have not already checked it out.
