      Hi Ryan,

      Solar powered flagpole lighting is a common application but only makes
      economic sense when it is more expensive to run conventional grid supplied
      power to the site than light it with a stand alone PV, battery and lighting
      system. One of the issues that affect cost is the amount of autonomy (how
      many days you want the system to work before the next good sun day - witness
      our recent and extended overcast weather) you want built into the system.
      If you want it to work for 2,3 4 or more days whether we get sun or not, the
      cost goes up. Do you have a budget you are trying to stay within?
