A Better Approach to Tracking

The key to InteliTrack’s design is keeping the PV array in balance no matter how the array is positioned.  We do that by mounting each PV panel on its own central axis allowing it to pivot back and forth as it follows the sun each day.  Because they are rotating on their own axes, each panel is perfectly balanced and takes only milliamps to move it.

Then we mount the supporting structure on its own horizontal axis so it can rotate up and down as it follows the sun as it moves between north and south during the year. 

This balanced scheme fundamentally changes the dynamics and cost structure of dual-axis tracking systems in several ways:

 1.  It’s not fighting gravity:

  • no massive foundation is required to keep it upright
  • you don’t need heavy-duty framing, gears, axles or motors to move the panels
  • you don’t need heavy earth-moving equipment or a crane for installation
  • the system is lightweight

2.   It doesn't fight the wind:

  • with its low-to-the-ground design, the array encounters lower-force winds
  • the space between panels allows the wind to slip through so the array isn't a giant sail for the wind to push against
  • we park the array with panels rotated to 45˚ so the wind either:

- passes between the panels
- strikes only the end panel on each row, so it encounters a very small surface and the
    panels behind the end panel create turbulence weakening the wind's force
- strikes the panels at an angle, so the force on the array is lowered 

3. Pivoting design:

  • the system can be low-to-the-ground making assembly quick and easy without heavy equipment
  • the panels can be rotated to convenient positions for cleaning and maintenance so that man-lifts or other special equipment are not required

By keeping the PV array in balance, no matter how the array is positioned, we save you money.

How We Produce More Power

A solar panel generates maximum power when sunlight strikes it perpendicularly.  As the angle to the sun drops off from perpendicular, the amount of power produced also drops off.  InteliTrack constantly repositions the solar array to face the sun as directly as possible generating 40% or more power than a fixed frame array.*

InteliTrack generates 40% or more power than a fixed frame.*

*Performance may be higher or lower depending on your installation.

Why Two Axes?

As the sun moves from north in the summer to south in the winter and back again, it shifts the angle at which its rays strike the earth.  One tracker axis follows the sun in its north-south movement while the other axis follows it as it moves from east to west each day.

Because it rotates on 2 axes, InteliTrack can generate 20% or more power than a single-axis tracker.

Optimizing the Sub-optimal or Why we say “40% or more".

While utility-type solar projects are designed to perfectly orient the PV array to true south, most smaller projects are not.  That’s because commercial, industrial, parking lot and residential projects are designed to fit existing spaces – rooftops, parking lots, or open space bounded by streets, fences and so on.

For these sub-optimally aligned projects, a fixed frame array produces less than its rated power, often much less.  Single-axis tracking can improve performance, but InteliTrack can overcome the limitations completely.  Because of its unique ability to tilt in two directions, InteliTrack delivers the Maximum Possible Power in any situation.

Note that in this illustration, the arrays on each parking structure all face the sun, but each array is tilted differently in relation to it base.  In some installations, the sun can actually be north of the array on summer mornings or afternoons, so that a fixed or single-axis array would get little or no sun at all.  Not so with InteliTrack.

InteliTrack delivers the maximum possible power.
