Sunflower ST12 Solar Tracker

Tracks East-West daily (adjust seasonal adjustment manually)

 

Get a LOT more power out of your Solar Panels!

This tracker will increase your solar input by quite a large percentage (30-55%). It follows the sun every half an hour to maximize the efficiency of your panels. Considering the cost of mounting panels properly even on a static mount, this unit is a must buy. For pumping you will get many more hours per day by using a tracker.

Efficiency use of tracker depends on the latitude of the region and time of season: in New South Wales at summer time maximum increase of daily energy output is 55%, in Tasmania at winter daily energy  gain reduces to 30%. 

It has some very good features:

  • Increases the input of your solar panels upto 50%
  • Tracks the Sun accurately
  • Returns to face East overnight (if  battery used to power unit)
  • Can be driven direct off the solar panels 
  • Has relatively good success on cloudy days (normally a big problem for trackers)
  • Rated for high wind speeds
  • Can hold upto 12  x 115watt panels (12m2)
  • Heavy-duty low speed motor is completely protected against overload.
  • Electronic Control Unit works in 2 seconds pulse working and 60 seconds waiting period mode .
  • Two Photovoltaic Diodes always pointing the unit to the brightest spot in sky.
  • MOSFET transistors make Control Unit more reliable compared to the conventional units on relays.
  • During accelerated tests tracker performed 4,000 tracking cycles, representing 11 years of field operation. Little wear only has been observed on components of the driving unit.

We have been testing & using a Sunflower Tracker for a little while. We have noted a marked increase in energy input from our panels. The unit has prooved reliable so far  - though did take quite some adjustments upfront. We found the instruction manual for assembly inadeuate - but that may have been due to the fact the manual is designed for the STD12 & we bought the STD16. We recommend people use & buy the STD12 as the larger 16 model needs a very expensive double pole mount at the bottom. Each tracker needs a mounting pole that you supply. The 2 poles needed for the larger STD16 make the unit too expensive to install & two smaller units would be a better option. We also found that support reply emails took too long & were not informative. For now we are selling this tracker at a lower rate than the manufacturer and will provide better support for our customers.

 

Smaller units available (from 2 - 16 panel models available)
