This Solar Powered Movable Lighting Tower includes 6 nos. solar panels, solar charging system, 192VDC battery bank and mounted on trailer with outriggers and removable tongue. In order to optimize the sun capture, the panels are set to +/- 15 degrees of the latitude of the trailers location on the earth.Houston, Texas, for example, is at latitude of 30 degrees, so the winter setting is 45 degrees and the summer setting would be 15 degrees. While this doesn’t make a huge difference, every little bit helps. Once the panels are set the correct solstice position, one section of panel is elevated into position via a manual crank winch system. This sets one set of 3 panels above the other section of three panels so they make a consistent plane angle to the sun. The entire panel deployment can be done easily by one person, since the axis system and manual winch support the weight of the panels during positioning. The entire process takes just a few minutes.
