Solar Panel Working System

 Introduction:

In recent years, solar panels have become increasingly popular as a renewable energy source. They convert sunlight into electricity, making them an ideal alternative to traditional power sources. In this blog, we will discuss how solar panels work and the science behind their functioning.

The Science Behind Solar Panels:

The basic functioning of solar panels is based on the photovoltaic effect. When sunlight falls on the surface of a solar panel, the energy from the sunlight is absorbed by the photovoltaic (PV) cells. PV cells are made up of silicon, which is a semiconductor material. When sunlight is absorbed, it knocks electrons off the silicon atoms, creating a flow of electrons. This flow of electrons is known as an electric current.

What is the Solar Panel System?

A solar panel system is a system of interconnected assembly (also known as an array) of photovoltaic (PV) solar cells.

The energy produced by the solar panel is measured in volts or watts. It will vary according to the type of system and the solar cell you are using. Each of the array’s solar panels (modules) consists of a group of solar cells packed jointed in a metal frame.

A single solar panel typically consists of 60, 72, or 96 solar cells. Every solar cell includes an inverter to convert the direct current produced into the alternating current electricity used in the home. The placed inverter can be large and centralized.

Working of Solar Panel

Solar panels receive sunlight as a source of energy to produce electricity or heat. A photovoltaic module is usually a connected combination of photovoltaic solar cells. Photovoltaic modules constitute the photovoltaic array of a photovoltaic system that generates and supplies solar electricity in many applications. Each module is rated under standard test conditions by its DC output power, typically ranging from 100 to 365 watts.

The efficiency of a module given the same rated output, as an 8% efficient 230W module will have twice the area of a 16% efficient 230W module. Some commercially available solar modules exceed 22% capacity and reportedly even exceed 24%.

A single solar module can provide only an inadequate amount of power. Most of the installations include multiple modules. A photovoltaic system includes an array of PV (photovoltaic) modules, an inverter, interconnection wiring, a battery pack for storage, and a solar tracking mechanism optionally.

The most general application of solar panels is solar water heating systems.

Factors Affecting Solar Panel Performance:

Several factors can affect the performance of solar panels. One of the most important factors is the amount of sunlight that the panels receive. The more sunlight the panels receive, the more electricity they can produce.

Other factors that can affect performance include temperature, shading, and the angle and orientation of the panels. It is important to ensure that solar panels are installed in a location where they receive maximum sunlight throughout the day, and are not shaded by trees, buildings or other objects.

Types of Solar Panel

Following are the different types of solar panels classified according to the generation of solar panel:

Monocrystalline Solar Panels (Mono-SI)

Polycrystalline Solar Panels (Poly-SI)

Amorphous Silicon Solar Cell (A-Si)

Thin-Film Solar Cells (TFSC)

Biohybrid Solar Cell

Concentrated PV Cell (CVP and HCVP)

Cadmium Telluride Solar Cell (CdTe)

According to Green Match following are the different types of solar panels made of monocrystalline silicon or polysilicon and are commonly used in traditional environments.

1 Monocrystalline Solar Panels (Mono-SI)

The monocrystalline solar panel is made of monocrystalline silicon is the purest. They are available in the form of an equally dark look and rounded edges. The reason for the high purity of silicon is that this type of solar panel has the highest efficiency of above 20% rate.

The benefits of using monocrystalline solar panels have a higher power output, occupy less space, and last longer. They are also costly compared to other types of solar panels. Another benefit to consider is that they are slightly less affected by high temperatures than polycrystalline panels.

2 Polycrystalline Solar Panels (Poly-SI)

The polycrystalline solar panels have a unique look than other panels. This type of solar panel has squares, and its angles are not cut. The appearance of this panel has a blue and speckled look.

These solar panels are manufactured by melting the raw silicon, which is a quicker and less expensive process compared to monocrystalline panels.

3 Amorphous Silicon Solar Cell (A-Si)

These are the different types of solar panels that one uses mainly in the manufacture of a pocket calculator. The amorphous silicon solar panel uses triple-layered technology, which is the most excellent of the thin film variety.

The thickness of this solar sheet is around about 1 micrometer. It is approximately about one-millionth of a meter. With only a 7% efficiency rate, these cells are less efficient than crystalline silicon ones, which have an efficiency rate of circa 18%. The benefit of using this solar panel is that it is available at a low cost.

4 Thin-Film Solar Cells (TFSC)

Thin-film solar panels are also known as TFSC. These are made by placing one or more films of PV material, such as silicon, cadmium, and copper, on a substrate. They are easy to produce, and economies of scale make them cheaper than options due to the low content required for their production.

Thin-film solar cells are flexible and less affected by high temperatures. Using these solar cells, opens up plenty of opportunities for alternative applications. The disadvantage of these solar cells is that it takes more space, generally making them unsuitable for residential establishments.

Furthermore, they offer the lowest warranty because their lifespan is shorter than mono- and polycrystalline-type solar panels. It is best to installment where a lot of space is available.

5 Biohybrid Solar Cell

The biohybrid solar cells were founded by an expert team from Vanderbilt University. The concept of this new technology is to take advantage of Photosystem 1 and thus simulate the natural process of photosynthesis.

Many of the materials applied in this cell are related to traditional methods. Combining multiple layers of photosystem 1 makes the transformation from chemical to electrical energy more efficiently. That is 1000 times more effective than the first-generation types of solar panels.

6 Concentrated PV Cell (CVP and HCVP)

Compared to other types of solar panels, such CVP cells have a name that makes them so efficient: curved mirror surfaces, lenses, and sometimes cooling systems are also used to bind the sun’s rays, and thus their efficiency increases.

Concentrated PV cells produce electrical energy as traditional photovoltaic systems do. The efficiency rate of those multi-junction type solar panels is 41%, one of the highest of all photovoltaic systems.

7 Cadmium Telluride Solar Cell (CdTe)

In these different types of solar panels, cadmium telluride is used in this photovoltaic technology. That allows the production of solar cells at a meager cost and thus a shorter period (for less than one year).

In all solar energy technology, it requires minimal water for production. The advantage of using these solar cells will keep their carbon footprint as low as possible. The main drawback of using cadmium telluride is its quality of being toxic if ingested or inhaled.

Especially in Europe, as many people are very concerned about using the technology behind this type of solar panel, this is one of the biggest hurdles to overcome.

Conclusion:

Solar panel technology has come a long way in recent years, making it an increasingly popular source of renewable energy. Understanding how solar panels work and the factors that affect their performance can help consumers make informed decisions about installing solar panel systems. With the right installation and maintenance, solar panels can provide a reliable and sustainable source of electricity for homes and businesses alike.

Windmill Working System.

 1. Introduction

The wind energy is an environment-friendly and efficient source of renewable energy. The kinetic energy of the wind can be used to do work. This energy is harnessed by windmill in the past to do mechanical work. This is used for water lifting pump and generating electricity. To generate the electricity, the rotary motion of, the windmill is used to turn the turbine of the electric generator. The output of single windmill is quite small and cannot be used for commercial purposes. Therefore, a number of windmills are erected over a large area, which is known as wind energy farm. The each and every windmill is coupled together to get a electricity for commercial purposes. The wind speed should be higher than 15 Km/hr.

2. Components of a Windmill Working System

2.1 Rotor Blades - 

The blades are the most recognizable part of a windmill. They are usually made of fiberglass or wood and are designed to be aerodynamically efficient to capture the maximum amount of wind energy.

2.2 Rotor Hub - 

The rotor hub is the central part of the windmill where the blades are attached. It is connected to the gearbox that converts the rotational motion of the rotor into electricity.

2.3 Gearbox - 

The gearbox is a complex mechanical device that increases the rotational speed of the rotor and converts it into electricity.

2.4 Generator - 

The generator is responsible for converting the mechanical energy from the gearbox into electrical energy. It consists of a rotor and a stator, with the rotor rotating inside the stator.

2.5 Tower - 

The tower is the tall structure that supports the entire windmill. It is usually made of steel or concrete and is designed to withstand high winds and extreme weather conditions.

3. Materials and methods

3.1 Windmill using multi generator

The two electromagnetic induction generator are connected in both end of the shaft through coupling. The windmill rotor transmit the power to the two generator through straight bevel gear. The power output of multi- generator used windmill will be two times of single generator used windmill.

3.2 Principle of the methods

The windmill is works on the principle of generating power through the force of the nature (air). The blades of windmill are rotated due to the force of wind strikes them. The rotating blades are transmitting the power to the generator through the shaft and gear box and generate the electricity.

3.3 Construction of the methods

For Horizontal blade wind turbine, the main parts are follows below:

• Blades and rotor,

• Electromagnetic Induction Generator

• Gears (straight bevel gear mechanism),

• Shaft.

The blades are attached with rotor by using bolt and nut. The rotor connected with gear through shaft and balance by bearing. The gear box consists of driver and driven gear. The driven gear teeth are mesh with driver gear. The one end of the low speed shaft is connected with driver gear and other end is connected with rotor turbine of the windmill. The long high speed shaft is connected at the center of the driven gear. The both end of the shaft is connected with two same or different generator through coupling.

The blade is attached with rotor. The rotor connected with straight bevel gear through shaft. The gear box consists of driver and driven gear. The one end of the low speed shaft is connected with driver gear and other end is connected with rotor turbine of the windmill. The long high speed shaft is connected at the center of the driven gear. The both end of the shaft is connected with two same or different generator through coupling.

3.4 Poles of generator

The one of the Generator is rotated at clockwise and other one is rotated at anticlockwise. The anticlockwise rotating Generator is not giving the current. So, we change the poles inside the motor. The poles of two motor is parallel and connected with driven gear through long shaft.

3.5 Working of the Method

The rotor is rotated due to the force of wind strikes the blades of windmill. The rotating blades are transmitting the power to the gear box (driver gear) through rotor from the shaft. In gear box, the straight bevel gear mechanism is used which consist of driver and driven gears. The driver gear is transmitting power to the driven gear. Finally, the gear box is transmitting power to the two Generator through shaft in driven gear. The Generator shaft is rotated and same torque is produced. Because, torque is product of force and area so we balance the force and area the torque will be same. The Generator generates current.

4. Wind power Equation

The Wind power Equation is a mathematical formula that is used to calculate the amount of power that can be extracted from the wind. It takes into account several variables, including the density of the air, the wind speed, and the size of the rotor blades. The equation is as follows:

Power = 0.5 x Density x Area x Velocity^3

where:

• Power is the amount of power that can be extracted from the wind (in watts)

• Density is the density of the air (in kg/m^3)

• Area is the area swept by the rotor blades (in m^2)

• Velocity is the wind speed (in m/s)

4.1 Variables in the Wind power Equation

• 4.1.1 Density -

• The density of the air is an important factor in the Win dpower Equation because it affects how much air the rotor blades can capture. Air density decreases as altitude increases and temperature rises, so wind turbines at higher altitudes or colder temperatures can produce more power.

• 4.1.2 Area -

• The area swept by the rotor blades is also a critical factor in the Wind power Equation. Larger blades can capture more wind energy, but they also require a stronger tower and foundation to support the extra weight.

• 4.1.3 Velocity -

• Wind speed is the most significant factor in the Wind power Equation, as it has the most significant impact on power production. As the wind speed increases, the power produced by the turbine increases exponentially. However, turbines are designed to operate within a specific wind speed range to prevent damage.

The control system is responsible for managing the speed and direction of the train, as well as the braking system. The control system receives information from sensors throughout the train, which allows it to make adjustments as necessary. The control system ensures that the train operates safely and efficiently.

Section 2: The Components of an Electric Train

An electric train is made up of several key components, including the locomotive, the passenger cars, and the electrical system. The locomotive is the engine of the train, containing the electric motor, batteries, and control systems. The passenger cars are where the passengers sit or stand during the journey, and they may also contain amenities like bathrooms, food service areas, and sleeping compartments.

Electric trains are a popular mode of transportation all over the world. They are efficient, fast, and environmentally friendly, making them an excellent option for commuters and travelers. But what exactly goes into making an electric train? In this post, we'll take a closer look at the components of an electric train and how they work together to make the train function.

The Locomotive

The locomotive is the engine of the train and is responsible for providing the power that propels the train forward. The locomotive contains the electric motor, batteries, and control systems that are necessary for the train to function. The electric motor converts the electrical energy from the power source into mechanical energy, which drives the train's wheels.

The Passenger Cars

Passenger cars are where the passengers sit or stand during the journey. They can vary in size and layout depending on the type of train and its intended use. Passenger cars may also contain amenities like bathrooms, food service areas, and sleeping compartments.

The Electrical System

The electrical system is responsible for delivering power to the train's electric motor. There are a few different ways that this can be done, including an overhead catenary system, a third rail, or a rechargeable battery. The electrical system includes the power supply, the electric motor, and the control system, which manages the speed and direction of the train.

The Braking System

The braking system is a crucial safety feature of the train. It allows the train to slow down and stop quickly if necessary. There are several different types of brakes that can be used on an electric train, including regenerative brakes, friction brakes, and electromagnetic brakes.

The Couplers

Couplers are the mechanical devices that connect the different cars of the train together. They are designed to allow the cars to move independently while still remaining attached to one another. The type of coupler used on a train will depend on the type and size of the train.

The Wheels and Axles

The wheels and axles are what allow the train to move along the track. The wheels are made of steel and are designed to provide a smooth ride while also being able to withstand the weight of the train. The axles are what connect the wheels to the train's body, allowing them to rotate freely.

Section 3: The Electrical System

The electrical system of an electric train includes the power supply, the electrical motor, and the control system. The power supply delivers electricity to the motor, which converts the electrical energy into mechanical energy to move the train. The control system manages the speed and direction of the train, as well as the braking system.

The electrical system is responsible for delivering power to the train's electric motor, and it can be broken down into several different components.

Power Supply: 

The power supply is what delivers the electricity to the train. It can be an overhead catenary system, which uses a wire strung above the tracks to deliver electricity to the train through a pantograph. It can also be a third rail, which is a low-voltage rail located beside or between the tracks that delivers electricity to the train through a shoe. Alternatively, the train can be powered by a rechargeable battery that is charged at specific intervals along the track.

Electric Motor: 

The electric motor is what converts the electrical energy delivered by the power supply into mechanical energy, which is used to drive the train's wheels. Electric motors can be either AC or DC, and they come in different sizes and power outputs, depending on the type and size of the train.

Control System: 

The control system is responsible for managing the speed and direction of the train, as well as the braking system. It receives information from sensors throughout the train, allowing it to make adjustments as necessary. The control system ensures that the train operates safely and efficiently. It can also be responsible for managing the distribution of power to the electric motor to ensure that it operates at its most efficient level.

Transformer and Rectifier: 

For trains that use an overhead catenary system, the electrical energy delivered by the power supply is high-voltage AC power. This needs to be transformed into the appropriate voltage and type of current required by the electric motor. The transformer and rectifier are responsible for this process, changing the high-voltage AC power to low-voltage DC power, which is what the electric motor requires.

Inverter:

 For trains that use a rechargeable battery, the inverter is an essential component. It is responsible for converting the DC power stored in the battery to AC power, which is required by the electric motor.

Overall, the electrical system is a critical component of an electric train. It provides the necessary power to propel the train forward and allows it to operate efficiently and safely. The specific components of the electrical system can vary depending on the type and size of the train, but they all work together to provide a smooth and reliable ride.

How the Train Working System Keeps Trains Running Safely and Efficiently

Intro:

Trains are an essential mode of transportation that move millions of people and goods around the world every day. But have you ever wondered how trains are able to run smoothly and safely on the tracks, especially when there are so many of them sharing the same network? The answer lies in the train working system, a complex set of rules and procedures that govern how trains operate on the railway. In this article, we'll take a closer look at how the train working system works and why it's so important.

Section 1: The Basics of Train Working System

Definition of the train working system and its main objectives

The different types of train working systems (e.g., absolute block, permissive block, etc.)

How train working systems differ between countries and regions.

The train working system is designed to prevent collisions between trains by ensuring that only one train occupies a specific section of track at any given time.

The system is based on a series of blocks, which are sections of track that are either occupied by a train or unoccupied. A train can only enter a block if it's unoccupied and the train working system permits it to do so.

The system is also designed to prevent two trains from entering the same block simultaneously by requiring one train to wait for the other to clear the block before proceeding.

The train working system is typically managed by a control center or dispatcher who monitors train movements and issues instructions to train crews as needed.

Train crews are responsible for following the train working system rules and procedures, including obeying signals, adhering to speed limits, and communicating with the control center as necessary.

The train working system also includes provisions for handling emergencies or unexpected events, such as broken-down trains or track obstructions.

Different types of train working systems may be used depending on the specific needs of the railway and the type of trains being operated. For example, a high-speed rail system may require a more advanced train working system than a traditional commuter rail network.

The train working system is continuously evolving as new technologies and best practices are developed. For example, some railways are now experimenting with using artificial intelligence and machine learning to improve train control and optimize train movements.

Section 2: Components of Train Working System

Signaling: the different types of signals (e.g., semaphore, color light, etc.) and how they are used to control train movements

Interlocking: the system that prevents conflicting movements by locking switches and signals

Train control: the methods used to ensure safe separation between trains (e.g., timetable, train order, track warrant, etc.)

Communications: the ways that train crews, dispatchers, and other personnel communicate with each other to coordinate train movements

Signaling is one of the most important components of the train working system. It provides visual cues to train crews about the state of the track ahead, including whether it's clear or occupied by another train.

Different types of signals may be used depending on the railway's specific needs and the type of trains being operated.

Interlocking is another key component of the train working system. It's a mechanical or electronic system that ensures that only one train can occupy a specific section of track at any given time. Interlocking is achieved through the use of switches and signals, which are controlled by the train working system to prevent conflicting movements.

Train control is the process of managing train movements to ensure that trains operate safely and efficiently.

  This may involve creating a timetable that specifies when and where trains will operate, issuing train orders to train crews, or using more advanced technologies like track warrants or automatic train control.

Communications play a crucial role in the train working system by allowing train crews, dispatchers, and other personnel to stay in touch with each other and coordinate train movements. This may involve using radios, telephones, or other communication devices to share information about track conditions, train locations, or other important details.

The train working system also includes various safety features, such as track circuits that detect the presence of trains, speed restrictions that limit how fast trains can travel, and emergency brakes that can be activated if a train needs to stop suddenly.

Train working systems are often designed with redundancy in mind, meaning that there are multiple layers of protection in place to prevent accidents and ensure that trains can continue to operate even if one component of the system fails. For example, if a signal fails, there may be a backup signal nearby that can be used instead.

Section 3: Safety and Efficiency Benefits of Train Working System

How the train working system helps prevent accidents and minimize delays

Examples of incidents that occurred when the train working system failed or was not followed properly

The role of technology (e.g., automatic train control, positive train control, etc.) in improving train working system safety and efficiency

One of the main benefits of the train working system is that it helps to prevent collisions and other types of accidents. By ensuring that only one train occupies a specific section of track at any given time, the system reduces the risk of trains running into each other or colliding with other obstacles on the track.

The train working system can also help to improve the overall efficiency of train operations. By optimizing train movements and minimizing delays, the system can help to reduce the time it takes for trains to reach their destinations and increase the number of trains that can be operated on a given section of track.

Another benefit of the train working system is that it can help to reduce the workload for train crews by automating certain tasks and providing them with real-time information about track conditions and train movements. This can help to improve safety and reduce the risk of human error.

The train working system can also help to reduce the environmental impact of train operations by minimizing the amount of fuel and energy required to move trains from one location to another. By optimizing train movements and reducing delays, the system can help to reduce the overall carbon footprint of the railway.

The train working system can be customized to meet the specific needs of different types of railways and train operations. For example, a high-speed rail system may require a more advanced train working system than a traditional commuter rail network. By tailoring the system to the specific needs of the railway, it's possible to achieve the best possible balance between safety, efficiency, and environmental sustainability.

Overall, the train working system is a critical component of modern rail transport. By providing a framework for managing train movements, preventing accidents, and optimizing train operations, the system helps to ensure that trains can operate safely, efficiently, and sustainably in a wide range of different settings.

Conclusion:

The train working system may seem like a complicated and technical topic, but it's essential for ensuring that trains can operate safely and efficiently. By following established rules and procedures and using advanced technologies, railway operators can keep trains running smoothly and avoid potential accidents or delays. Whether you're a train enthusiast or a regular passenger, it's worth taking the time to learn about the train working system and appreciate its role in keeping our railways moving.
