Solar tracker

Solar tracker is a gadget that keeps a track of the movement of the sun and rotates itself according to the position of the sun. The solar trackers work by keeping the solar panels, or solar collectors pointed towards the sun directly. They change their position to absorb maximum tern amount of energy from the sun. With the help of the solar trackers, the output energy can be enhanced up to 30% more. Opting for solar trackers is a wise choice if you are looking forward to increasing the amount of energy conserved from the sun.

Types of Sun tracking solar panel

The basic function of all the solar tracker is quite the same. They are all designed to follow the movement of the sun. They are mostly used for solar thermal technology as they use the optics for generating a high amount of heat. So, to get the maximum amount of energy, the solar panels must be oriented towards the sun the entire time. Now, there are different types of solar trackers. So, let us have a look at them.

Passive trackers

These kinds of trackers use a compressed gas fluid of low boiling point so that the tracker can direct itself towards the sun in case there is an imbalance. But the major disadvantage for these solar trackers is that they aren’t precise. It works fine for the common PV panels but is not recommended for concentrating photovoltaic collectors.

Active Trackers

These trackers use a motor and gears for guiding itself towards the sun which is all controlled by a controller. These are energy consuming as the motors are powered by energy that is driven from the panels, so, it is recommended to use them only if necessary.

Single axis trackers

These kinds of trackers have four subdivision, they are

  1. Horizontal single axis trackers (HSAT)
  2. Vertical single axis trackers (VSAT)
  3. Tilted single axis trackers (TSAT)
  4. Polar aligned single axis trackers (PSAT)

Since these trackers only work on a single axis, they can move only in a single direction. These trackers are usually aligned on a North Meridian. Thought the direction of these trackers could be changed using the advanced algorithm.  

Dual axis solar tracker

The Dual Axis trackers can two rotate in two degrees. It has two subdivision, they are:

  1. Tip-tilt dual axis trackers (TTDAT)
  2. Azimuth-altitude dual axis trackers (AADAT)

Price of solar trackers

These solar trackers come in a variety of prices. Below is a table where you will get all the necessary information about them.

Axis Type Tracker Type Price
Single Axis Vertical, Single Axis Tilted, Single Axis Horizontal Active Tracker INR 10,000
Dual Axis Active Tracker INR 75,000
Single Axis Horizontal, Dual Axis Tip-Tilt Passive Tracker INR 20/watt

 

Note: The data given in the above table is to help you to avail proper information. The actual price of the solar trackers may vary from state to state. The practical efficiency may also vary depending on the manufacturer and size of the product.

FAQs

Why are solar trackers required?

Solar tracker is the best way for conserving the maximum amount of solar energy by using a solar tracking system and by controlling the direction of the solar panels. The solar panels can be moved automatically, i.e., is a passive tracker or by using a controller, i.e., active trackers.

What are dual axis solar trackers?

Dual trackers the freedom to rotate in two degrees, the fixed axis, also known as the primary axis is fixed to the ground, while the corresponding axis is known as the secondary axis. The primary axis is decided based on the ground. The primary axis rotates the panels while the secondary axis tilts the panel according to the direction of the sun. Dual axis trackers are typically used in smaller residence or location where there is a high feed tariff of the government.  

Benefits of using solar trackers

Apart from changing direction, the solar trackers come with some additional benefits, they are:

  • They generate an extra amount of electricity in comparison with the fixed solar panels since they have extra exposure to the sun
  • They come in binary formats that are the single axis and the dual axis. So, you can choose whichever suit your needs.
  • They need the same amount of space as fixed panels yet produce more electricity. So, they are a great option for land optimization

  1. SOLARSAN-GPS V17 (WiFi MQTT)
    Complex for tracking the sun based on the calculation of data received from the GPS receiver. This system consists of a basic module SOLARSAN-GPS, which can work independently, and SOLARSAN-SLAVE only works as an executive device. Using SOLARSAN-GPS, you can configure solar concentrators, collectors or panels at right angles to sunlight. Control is carried out with the help of drives or rotary actuators in two planes and has an accuracy of one degree. The module has an input to connect an “anemometer” to protect against strong wind, the input of the “hail and snow sensor” and the input of the “photo-sensor” for sleep with low solar activity. The WiFi module allows you to configure the tracker through a WEB page or a local network. The built-in MQTT broker allows you to manage and retrieve data via the Internet network around the world. Power supply from 12 to 30 V (and version HV with a power of 12 V to 55 V). Protection by current. Short circuit protection. Built-in radio modem 433.92 (315.00) MHz with a capacity of 100 mW for data transmission in a radius of up to 100 meters for modules SOLARSAN-SLAVE. Works both in one and two axes. The IP66 enclosure allows you to install a solar tracker under the open sky.
