Abstract: A mobile utilities station includes a plurality of batteries charged by sheets of photovoltaic cells, all mounted in a trailer. The mobile utilities station provides various utilities, for example, electricity, water purification, HVAC, communications, etc. When available sunlight is insufficient to operate all of the devices in use, electricity is supplemented from the batteries. The batteries also power the devices at night. During periods of low usage, the photovoltaic cells recharge the batteries.
