I assume this situation is also solar-powered. What is the range over 
which the school server has to be accessible? Do you wire the APs back 
to the central location or provide solar power directly to each?

I fully agree that the school server needs its own power in a solar 
environment. At the first school in Lesotho, the solar installation 
provides more than enough power so that the server did not require 
additional panels. However, additional panels were installed to enable 
the server to be located nearer to the 'computer room' when it was 
expected all computer classes would be conducted in that room.

At the second school, the laptops are charged from individual panels so 
that the school server needs a dedicated solar panel and set of batteries.

Even in the community server situation, I would expect it would be on 
say from 0700-1100 and shut down overnight.
