Comparative Analysis of Different types of Solar Photovoltaic Tracking Systems

Solar energy is a vast, abundant, cost-free, green renewable source of energy. Due to the aforementioned qualities, the world is today researching and exploring the most feasibly optimized way of harnessing this energy and a solar tracking system is a result of this quest.

The aim of this article is to provide a comparative analysis of different types of solar photovoltaic tracking systems. 

We tried to answer the following scopes in our analysis :

a. Research and identify the required knowledge related to the given problem. (Review the given

technical article and prepare a problem statement- Why solar tracker?)

In Photovoltaic systems solar trackers are designed to reduce the angle of incidence of sunlight falling on solar panel. It is well known, when incident light from sun is at 90 degree, the solar radiation falling on the panel is more and due to this more solar energy is utilized. Concentrated sun oriented photovoltaics and concentrated sun powered warm have optics that straightforwardly acknowledge daylight, so sun based trackers should be calculated effectively to gather energy. All concentrated nearby planet groups have trackers on the grounds that the frameworks don't deliver energy except if coordinated accurately toward the sun.

Choosing a Solar tracker always relies upon framework size, electric rates, land limitations, government impetuses, scope and climate. Utility-scale and huge undertakings generally utilize even single-pivot sun oriented trackers, while double hub trackers are for the most part utilized in more modest private applications and areas with high government Feed-In-Tariffs. Vertical-pivot trackers are appropriate for high scopes due to their fixed or customizable points.

b. Identify the key issues, variables, requirements, scopes, types, characteristics, advantages, disadvantages, domain, etc. of the solar photovoltaic tracking systems. (Which performs better considering different parameters in different situations. Prepare a comparative chart mentioning the key issues, variables, requirements, scopes, types, characteristics, advantages, disadvantages, domain, etc).

Key Issues

There can likewise be an issue with guarantees. A fixed-nearby planet group that will most recent 30 years as a rule accompanies a 25-year power execution ensure. In any case, a sun oriented followed framework comes just with a 5 to 10-year guarantee.

Requirements

1. Sensor.

2. Drives.

3. Softwares.

4. GPS

5. PV panels.

6. Power to drive the circuit

Characteristics

Sun oriented trackers utilize various drivers, programming and physical science to follow the sun's area. Dynamic trackers use drivers, which are engines connected to sensors responding to light from the sun or following GPS directions of its position. Some tracker models have discrete, more modest PV boards explicitly to control the driving framework.

Advantage of Solar Tracker

The advantage of sun oriented trackers can build power creation by around a third, and some case by however much 40% in certain districts, contrasted and modules at a decent point. In any sun powered application, the change effectiveness is further developed when the modules are constantly acclimated to the ideal point as the sun navigates the sky. As further developed effectiveness implies further developed yield, utilization of trackers can have a serious effect to the pay from an enormous plant. This is the reason utility-scale sunlight based establishments are progressively being mounted on global positioning frameworks.

Disadvantage of Solar Tracker

1. Adding a sun based global positioning framework implies added greater hardware, moving parts and pinion wheels, that will require standard support and fix or substitution of broken parts.

2. In the event that the sun based tracker framework separates when the sunlight based chargers are at an outrageous point, the deficiency of creation until the framework is practical again can be significant.

3. A sun oriented tracker is likewise more inclined to be harmed in a tempest than the real boards.

Types of solar trackers are:

1. Single-axis solar trackers.

2. horizontal, vertical, tilted, and polar aligned

3. Dual-axis solar trackers.

c. Provide proper comments to analyze different solar tracking systems using relevant analytical skills and fundamental knowledge of engineering to reach a substantiated conclusion. 

Different Solar Tracker system can be Concluded as:

1. Single-axis solar trackers.

It turn on one pivot moving to and fro a solitary way. Various kinds of single-pivot trackers incorporate flat, vertical, shifted, and polar adjusted, which turn as the names infer.

2. Dual-axis solar trackers.

It ceaselessly point toward the sun since they can move in two distinct ways. Types incorporate tip-slant and azimuth-height. Double pivot following is commonly used to situate a mirror and divert daylight along a decent hub towards a fixed collector. Since these trackers follow the sun upward and on a level plane they assist with getting most extreme sun powered energy age.
