The wattages vary slightly depending on the color/model, but the standard white or blue panels are 22w. Honestly sounds like you're putting together nearly the exact same setup I have, so I'll say that I've gotten really good color on everything I've put under white yescom panels when placed ~7" above the soil surface and still a decent amount of color at ~11". For my roughly 11x20" rack I use 1 panel per shelf, while my 36"x18" shelving gets by with 2 per shelf. They work really well with wire shelving because you can just remove the mounting wires from the clips and just use the clips alone to attach them to the shelf above, then run all your wiring across then down a corner post and secure it with some cheap zip ties.
