Power density numbers depend on monocrystalline vs. polycrystalline as well as voltage. Monocrystalline is a slightly different structure and gets better efficiency, so it will be smaller for a given amount of power but also more expensive. Higher voltage panels (e.g. 24v as opposed to 12v) generally are smaller for a given amount of power.
Here are a few numbers:
14.3 W / ft^2 for a Renogy 12v, 150W monocrystalline panel
16.0 W / ft^2 for a Renogy 24v, 280W monocrystalline panel
15.3 W / ft^2 for a Renogy 24v, 320W polycrystalline panel
