All You Need To Know About Solar Trackers

Solar panel installation is becoming widely accepted in various parts of the country because of the several benefits associated with its usage. However, advancements in technology make it easier for everyone to maximize their use, irrespective of their location or occupation.

About Solar Trackers

With the introduction of solar trackers into the solar industry, it is now possible for big companies who have issues with space to make use of solar panels while enjoying the maximum benefits attached to it. Solar trackers make it possible for solar panels to follow the movement of the sun. This helps to create a better angle of incidence for the sun rays to hit the solar panels. Solar trackers are specially designed for ground-mounted and free-standing solar installations, such as solar trees. There are two different types:

Single-Axis Tracker:

Single-axis trackers are designed to move solar panels along one axis of movement. This means the solar panel is either moving from North to South or East to West. Most of the time solar panels that are aligned to the East to West movement are preferred. Rationally it is better  to follow the rising and falling of the sun for higher efficiency production. Hence, the single-axis tracker is aligned with the north and south.

Dual-Axis Tracker:

The dual-axis tracker allows movement along both axes. This means that they are aligned in both north and south as well as east and west. This helps to get maximum energy from the sun because it basically follows the sun in all directions. The dual-axis tracker helps to track the daily motion as well as the seasonal variation in the sun.

Most companies prefer the dual-axis tracker because it helps to get maximum energy from the sun irrespective of the space. This is especially a better option for companies that do not have enough space to mount their solar panels. They can use the little space available while enjoying maximum energy input from the sun and output from the panel.

Merits And Demerits Of Solar Trackers

The main benefit of using a solar tracker is that you enjoy maximum energy output from the panel installed. This can save you a lot on electricity bills, as it offers a significant boost in electricity production. For instance, a single-axis tracker can offer more than 35% performance, while a dual-axis tracker offers up to 50% more energy production.

The main drawback of solar tracker installation is its cost of installation and maintenance. Because it is a somewhat complex technology, installation can be technical; hence it is quite expensive compared to fixing solar panels without trackers.

Another disadvantage is the heavyweight of the solar trackers. This makes it unfit for rooftop installation. Hence, anyone who wants to use a solar tracker should be prepared to do a ground-mounted solar panel installation.
