Trackers are generally used to direct the solar panels or modules to where the sunlight is. The gadgets will change direction throughout the day as the sun moves form east to west. This is the normal the normal path that the sun follows to and the device will ensure maximum energy is collected. The trackers that are inside a photovoltaic system are there to minimize the overall incidence angle of the incoming light and the modules (panels). The angle or incidence refers to the vertical line the sun rays will hit the surface. This will increase the levels of solar power generated by the panel.

The solar photovoltaic or CST (concentrated solar thermal) usually has optics that will accept the sunlight collected. Therefore, the tracker must be placed on the right position to maximize the amassment of energy. You can find trackers for every available CSP since the entire system cannot generate power unless it is placed on the right path of the sun. Benefits of Solar Power are so big that you can’t even imagine.

Single axis (trackers) – These types are usually made to move on one axis, which normally moves either back or forward in a solitary direction. You can find different types that will include horizontal, vertical, polar aligned and tilted types. The way the tracker rotates follows the way it has been named. For instance, for horizontal, it will move on a straight line.

Dual axis trackers – This type normally face the sun every time because it has been made to move in two different paths. The major ones available in this category include the azimuth altitude and tip tilt. The major role of these ones is to redirect or slant the mirrors or sunshine on the fixed axis to a stationary receiver. Because of the movement of these trackers either horizontally or in a vertical path; it ensures maximum solar energy is produced for use. Did you ever hear about boosting solar power?

Categories of trackers

The solar tracker can be moved using different techniques; the common methods utilized are listed below.

  • Passive tracker- This type only moves when the liquid gas is compressed and moves it in one direction to the other.
  • Active tracker- This design is operated by motors plus gears with the aid of a controller and will respond to where the sun’s direction.
  • Chronological tracker– This type will move through counteracting the earth’s rotations and will turn on the opposite side.

Factors that will influence the selection of the devices will depend on electric rates, weather patterns, and latitudes, incentives from the government, land restriction and size of your system. With a large scale project, you will require the single axis tracker. For the dual, residential areas and commercial centers are suited for them. For the vertical axis, areas with high latitudes are suitable because it comes with an adjustable or stationary angle. Solar trackers are known to increase the power generation by up to one third.
