  • Page 12: Sp305-L Mount Assembly

    For most tripod installations, the tripod is oriented with one leg pointing directly away from the equator. For most tower installations, the tower is positioned with one side oriented parallel to the equator. Keep the solar panel covered during assembly to prevent voltage output during the assembly process. SP50-L, SP90-L, and SP305-L Solar Panels...
  • Page 13 Use a level to ensure the mount bracket is level and fully tighten the nuts. For installation on a tower, the two U-bolts are used to attach the upper mount bracket to the tower legs closest to the equator. FIGURE 3-8.

    (night) and several days of low charging (cloudy and stormy days). Campbell Scientific has developed an Excel power budget spreadsheet that estimates the solar panel size and battery required for a system based on the components in the system, scan interval, communications interval, and location.

  • Page 29: Voltage Regulator

    5.2 Voltage regulator The solar panel must be regulated either with a Campbell Scientific regulator or a third-party regulator. The regulator has two basic functions: Blocking any current flow from the battery to the solar panel Limiting the source current to the battery The solar panel must be connected to the voltage regulator, not direct to the storage battery.
