Default Optimum tank depth?

I'm having a tank built but I'm not sure how deep I can make it? Will be lit with T5 tubes at 3watts/gallon and I'm wanting to carpet the entire substrate with hair grass.

So how deep can I go?

By "deep", do you mean height of the tank, or distance from front to back? If you want to be able to work on the aquascape, clean the glass, "fluff" the plants, etc. it is impractical to use a tank much higher than 2 feet. Very few of us have long enough arms to reach the bottom of a tank much higher. Front to back distance is also limited by our reach. If the tank is against a wall, that distance can't be much more than 18 inches or you can't reach the substrate at the back of the tank. People do use bigger tanks, but they also have to devise unusual techniques to do their maintenance. The most practical big tanks are long tanks, 6 feet long or longer.

I'm meaning max tank height to achieve adequate light penetration to the hair grass

Light from any type of lighting drops in intensity with the square of the distance from the light (roughly, but not nearly exactly). Light penetrates water, to any depth we would use, very easily so any tank you can reach to the bottom of with your hands, can be lighted as well as you want with a variety of different light fixtures. "Watts per gallon" is not a way to determine how much light you will have from any light fixture. You need to find a chart of PAR (photosynthetically active radiation) vs distance for the light fixtures you want to use. Then, pick a light fixture or group of light fixtures that give you the amount of PAR you need at the substrate level in your tank. If you want low light, that can be 30 - 40 PAR, or for medium light it can be 40 - 50 PAR, or for high light it can be something higher. The best way to do this is to borrow a PAR meter and actually measure the light you get from a specific light fixture at the distance it will be from the substrate.
