Solar Tracker "SunTracer OG+" SM3SPMOG+

The Sun Tracer Tracker is great for cabins, tiny homes, rvs  and for small solar water pumping systems.

Lead time is 1-2 weeks from order placement.

The Sun Tracer Tracker must be supplied with power from a 12 VDC power supply either using a seperate supply small battery or from solar panel if 12vdc. Suitable for panels up to dimensions 2m x 1m (usually 1 x 60 cell panel)

Max Wind resistance is 130km/h.  All metal gear parts inside ensure long life

Main pole support is not included in this solar tracker package! You can buy it separatelly and is normally available from any steel supplier. Size suggested is

Solar tracker anti-shadowing software function included.

Real energy measurement of two equal solar panels (fixed and motorized)

  • Two equal sized solar panels were exposed to the sun and electrical power was measured.
  • Test conditions:      
  • Solar panels (both):    200W (producer spec. at AM 1.5)
  • Date:                       July 2005
  • Time:                       4:00 to 20:00 (sun time)
  • Geo. Latitude:           46° N
  • Weather conditions:   sunny, but not totally clear
  • Results:       
  • Average energy of fixed:                836,8Wh
  • Average energy of motorized:        1354,0Wh
  • Note: sum of motor energy consumption through all day is 20Wh or 1.45% of all collected energy.

Efficiency of motorized panel: 160%
