Missionary brings Solar Power to the Mountain Jungles of the Philippines

      A Philippine missionary, EA, devotes her time to an isolated village in the backcountry mountain jungles of the Philippines.  In the village EA serves, there is no electricity, and the villagers have never experienced an electronic device, nor have they seen a movie or video.  It was EA’s desire to introduce both electricity and Christian movies to the people of the village, especially the children.  Access to the mountain village consisted of long backcountry trails that are hiked either by foot, by horseback, or by pack mule.

     EA approached Powerenz, Inc. with a very specific application – to assemble a transportable source of electricity that would provide enough power for a small projector to show a movie to the villagers during the evenings, and that would recharge itself in sunlight during the days.  The power system needed to be turn-key and foolproof, since there are very few people in the mountain jungles capable of testing and repairing such a device.  In addition, the system needed to be light-weight enough to be carried up the mountains on horseback, enclosed in a water-resistant enclosure in case of rain, simple to use, and durable.  The electrical devices that are sold in the Philippines generally require 220 volts AC.
      Powerenz assembled a portable solar panel-battery power system that consisted of the following:
         a.       42-watt, foldable, light-weight, water-proof solar panel
         b.      33 amp-hour, 12-volt, AGM, sealed lead acid battery
         c.       7-amp solar charge controller
         d.      continuous 300-watt, modified sine wave 12VDC-220VAC power inverter
         e.       12-volt female DC socket
         f.        water-resistant, heavy-duty carrying case
         g.       spare parts, fuses, etc.

     The completed system weighed approximately 38 pounds.  Due to the limitations on the total weight of the system, and, therefore, size of the battery, Powerenz recommended that EA purchase a small, energy-efficient movie projector that either used LED or fluorescent lighting, rather than energy-inefficient, excessive heat-producing, incandescent lighting.  It is difficult to locate such a movie projector.  Instead, EA purchased an energy-efficient DVD player with an LCD monitor/screen that uses LED-type lighting.  Based on the power draw specs of the DVD player, one 3-hour movie could be shown every evening using the power system.  During daylight hours, assuming good sunshine, the power system battery could be recharged in 6-8 hours, and be recharged and ready for the next evening’s movie.
