Someday we will harness the rays of the sun. - Thomas A. Edison
Tracker points your panel at the sun all day. You could get almost 50% more power from your panel - power that you would have now if your panel was pointed at the sun all the time.

TRACKER takes a panel on a journey throughout the day. From sunrise to sunset, your solar panel is treated to the full power of the sun.

Most people know that a solar panel can't provide its full rated power unless it's pointed directly at the sun. However, most panels get installed in a static, fixed position, usually pointing to where the sun should be at high noon. That's so it can get at least a little sun for most of the day.

But since the panel can't move, the only time it directly sees the sun is at noon. That means it loses out on a lot more available sun energy in the morning and afternoon simply because sunlight is hitting the panel at an angle instead of straight on.
 
In order to make up for the loss, a much bigger panel than necessary is often used. Sometimes more than one. This takes up more space, costs twice as much, and still doesn't deliver full working power for most of the day.
Notice in the figure above that by using TRACKER the panel is at peak performance 30-50% longer each day. That's because TRACKER silently moves your panel so it follows and faces the sun - from sunrise to sunset. It makes every hour a full power hour.
 
TRACKER lets your panel do its job all day instead of waiting for its short time in the sun. Even when it's cloudy or raining, your panel provides the most energy you can expect because TRACKER's patent-pending technology keeps your panel on the move, even following the sun through the clouds.

And at the end of the day, when the sun can't be asked for more, the panel is readied for sunrise the next morning when it will begin producing full power while other panels are still asleep.

Solar Panel Terminology
"insolation"
Term used to describe the measurement of solar radiation received on a given surface area, over a given period of time.
If the surface is perpendicular (90° angle) to the sun's rays, the insolation is at its maximum. As the angle is increased (panel is at an angle to the sun), the insolation decreases according to the cosine of the angle.
For example, if the sun is only 15° offset to the face of the panel, you lose over 25% of the panel's output power.
Thus, a statically mounted panel is only capable of 90% of its output power for just about an hour a day.
"Installed Tilt Angle"
The optimum angle at which the panel is mounted to the horizontal. This angle is the one tilt angle where a solar panel will produce the most electricity in a year's time.
The panel is always pointed true South in the northern hemisphere, and true North in the southern. However, the panel should also be angled upward to the Tilt Angle.
It is common practice to use a Tilt Angle of the latitude at the installation ±10°. Less of an angle if more Summer sun is desired, greater angle if more Winter sun is needed.
For example, if you are in Columbus, Ohio, optimum angle is 40° to the horizontal - level ground.
