A creek nearby? If you cannot take water from the creek directly, either because of contamination or volume of water present, perhaps you can use the water itself in a condenser. It would work the same as your very powerful refridgeration unit you plan on buying. But instead of pumping R12 and using several compressors, perhaps you can pump the creek water through tubing or fins. Then you can return the water back to the creek. The cooled tubing would create condensation just as the "dehumidifier" type of device you are planning on using. Pumping creek water may prove more cost effective power wise.
  If the creek has enough flow and volume to remove the required volume of water needed, solar distillation, water pasteurization and filtration may be an option at little or no cost for power. Distribution can be solved using smaller DC pumps each with their own small PV and/or battery.
 

The best thing for you is to contact some UN Development Agency that specialises in assisting developing nations with clean water options. Once the professionals in the field have identified the best solution(s) for your requirements, you can come back and get assistance with how best to power that option using renewable energy.

All of those "water from air" machines are basically scams. They will certainly produce water from air (as does any air conditioning unit), but water is a by-product of the process and more than 90% of the energy that goes into the unit is spent doing something else.
