This is about the most simple solar powered access point you could possibly build. It runs straight off the solar panel seen in the photo.

There is no battery or anything to store the energy. (as seen here ) While you would not be able to run the unit all night long you would however be able to run it all day long (as long as the sun comes up;-)

Would this easy to use type of setup be useful to you? Let us know what you think.
