Solar powered Wi-Fi access point

We have been experimenting with a solar powered access point using a low cost 12v 3W panel. 

The panel produces more than enough power during daylight hours to run a Engenius 2611 cb3 without the addition of any extra circuitry or battery packs.

With the addition of a small lead acid battery pack it could run the AP at night and on overcast days.

What could this be used for?  How about a solar powered repeater mounted in a remote sunny location.
