Jimmy,

We did such a project many years ago for a Gazebo fed through a point to point 
from a building.
It even worked at night during the winter (Latitude: Tennessee).

Here is a link with photos of the equipment.
The solar Panels have a Voltage of 12V and most APs these days can take 12V 
(our project was based on a Proxim AP-4000 that required 5V, hence the voltage 
converter).
So: solar panel 12V, AP 12V, Lead Battery 12V…all you need is a regulator 
between the Solar Panel and the battery!
