Could I use a couple sun traking silicon solar cells to power several garden lights?

I saw in http://www.instructables.com/id/Solar-PV-tracker/ that a sun tracking solar panel raises output by 30-50%...

I also saw garden lights with really small solar panels on them...

So i came up with an idea to use a couple solar panels to power a whole set of garden lights!
Is this possible?

Note: Is this idea cheaper than buying several solar powered garden lights?

[Re-design]

Unless you have a bunch of cells just laying around it will not be cheaper than just buying several garden lights.  The lights are really cheap and I think you'd have to spend double just to match them.  Maybe more.

If you build them you still have to pay for parts.

If you power them from tracking cells you will still need to buy almost as many as.

You still have the extra expense of the tracking mech.  AND get it working.  You'd have to lay wire to each light since they all share the same power system.

BUT,
If you want to do it as a learning experience the go ahead with the project it's an excellent construction/design project.
