2-axis solar trackers: how they optimize energy production

When installing solar panels at home, different factors must be taken into account. For example, if we are talking about a photovoltaic system made on land, it may be necessary to install a 2 axis solar trackerin order to adapt to the movement of the sun.

If you still don’t know what a solar tracker is, or how it optimizes energy production, this article is for you.

What is a solar tracker?

We can define a solar tracker as a type of mobile structure that will serve as a point of union between the solar panel and the ground.

The main objective of this architecture is optimize electricity production of said facility. To do this, it adapts to the best angle at which the sun’s radiation would be received.

The most common is that they are installed in large places.

If you plan to install solar panelsyou have to take into account that angle where lightning strikes is proportional to the energy generated. This is known as angle of incidence and it is used to measure the performance of the switchboard in transforming energy into electricity.

Keep in mind that the greater the perpendicularity of the angle, the more energy the system will be able to generate.

There are two main types of solar trackersalthough in this article we will focus on dual axis solar tracking system.

How does a 2-axis solar tracker work and how does it optimize energy production?

Unlike the single axis solar panel, a dual axis tracker has ability to move in two directions: in an east-west and north-south direction.

The main reason to opt for this type of device is to optimize the solar energy received throughout the year. And it is that they could change their orientation depending on the season of the year in which we find ourselves. And not only that, but they can follow the sun in a much wider range than the single axis model.

Besides getting much more accurate sun tracking and good performance, they also make it harder for your panels to be stolen.

However, it must be taken into account that the associated cost is higher.

It is possible to classify solar trackers into 2 main categories: automatic and manual control.

·The manual solar trackers They are the cheapest, ideal for all people who do not have a very high budget.

Instead, the automatic solar trackers They incorporate special microprocessors that allow them to follow the position of the sun using sensors. They can also have software with astronomical data to know the position of the star at all times.

What are the advantages of a 2-axis solar tracker?

In this section we detail the advantages of this device:

1. They increase system efficiency

Investing in these devices can allow the system to increase its performance between a 25 and 35% (in the case of a single axis system). If it is a two-axis system, the performance is increased on a 5-10% on the aforementioned range.

2. Long duration

As long as you invest in a high quality device, it can last approximately 30 years.

The approximate repayment term is 5-10 years. This means that we will be able to get profit for a few 22 years old about.

3. Allows you to enjoy the sun all year round

They are very convenient to place in places where the position of the sun varies a lot from morning to afternoon and from winter months to summer months.

The energy generated may be sufficient to encourage the Personal consumption At home.

If any inconvenience can be opposed to it, we will say that the Cost it’s a bit high. In addition, it should be borne in mind that maintenance also involves an investment of time and money.

Now you know how the solar trackers And why are they so useful?
