sTracker High Efficiency Dual Axis Solar Tracking System

The sTracker is a high efficiency low maintenance ground mount dual axis solar tracking system. Solar tracking aims solar panels at the sun all day long for maximum power. Solar absorption from dual axis tracking can produce almost twice the solar production per day over stationary solar panel installations.

The sTracker tilts to 60 degrees East and West.  90 degrees flat to 40 degrees South(user adjustable to below 40 degrees if needed).

Design

The sTracker is Designed for Simplicity and Reliability with Little to no Maintenance Requirements

 

The sTracker frame is made with extruded T6061 aluminum tubes and a powder coated steel post. Accurately designed with 3D cad software, manufactured with CNC machining, precision lasers, and TIG welded framing. The sTracker is structurally sound and certified to withstand the most extreme environments.  This includes very high windy conditions, seismic, gravity, and snow loads.

 

Pivot points use high load bearings with zinc plated shafts. Includes standard Ironridge XR100 rails. Most all solar panels can be mounted to the sTracker. Modular design for quick assembly.  Built to last a lifetime.

 

The control system provides accurate tracking and is configurable. Low power consumption linear actuators are used to move the structure with battery backup computer control.

Applications and Uses

If you are planning on building a solar farm, multiple sTrackers can be chained together like an army. The sTracker provides extreme solar power for agriculture and farming, and produces max power for late afternoon air conditioning when needed most. Supports Off-Grid and Grid-Tie, AC or DC coupled battery charging, electric vehicle charging. The list goes on.

Advantages Compared to the Typical Stationary Ground Mount

The sTracker is a ground mount solar system but produces more power per square foot compared to ground mount non-tracking/stationary systems. Solar tracking also reduces the amount of panels needed.  Typical ground mount racking and frames require even level surfaces. The modular design of the sTracker makes it possible to be placed on most all terrains, slopes and surfaces.  An sTracker can quickly be erected once the base is in place using either a cement filled hole with a flat surface, a cement pad or existing pad using concrete anchor bolts. 

Commercial Applications, Contractors and Distributors

 The sTracker is very reliable and designed for commercial use.  The sTrackers are manufactured in San Jose CA.  Our manufacturing facilitates high quality, high throughput and top notch solar tracking engineering.  We can supply and ship in volume.  We also offer complete turn key installations.

Return on Investment

Solar tracking output power

One tracking system can produce over 12 kWatt/hours a day in mid to southern latitudes spring to fall.  Depending on your situation, payoff times can be as low as 3 years. The sTracker can mount up to 1.6 Kwatts of solar panels using the current panel output technology. This equates to 2.2 kWatts because it is tracking producing 40% more solar power. Add more trackers for even more power.

We have crunched some of the numbers and came up with some ruff "Return on Investment" estimates for normal climates along the mid longitude areas such as San Francisco,CA and other outlying cities and suburban areas. We also used the PVWatts website to aid with our calculations.

Here are the the results:

 A Fixed/Roof system: 5-9 years ROI.

 A Suntactics solar tracker:  3-5 ROI.

Recommended placement with a multiple sTracker installation.  

For the DIYer, we can ship you an sTracker using freight nationwide.  

We can also install a complete solar tracking field for you. This includes analysis, surveys, acquiring permits, plans, placement, and everything else needed to get you up and running.  

 

We also offer a complete storage battery system in combination with the sTracker system.  We can get you very close to off-grid power independence.
