The operation of solar energy generation is simple and is done through solar panels. Solar panels consist of photovoltaic (PV) cells, which use light particles (photons) from sunlight to generate energy. Following are the steps of a solar energy system:

 

1. Absorption of sunlight

Solar panels absorb sunlight. Each solar panel contains silicon, or another semiconductor material, that absorbs photons from sunlight.

2. Electricity Generation by Photovoltaic Effect

When photons from sunlight strike the photovoltaic cells in a solar panel, these photons move the electrons in the cell. This creates an electric current in the electrons. This process is called the photovoltaic effect.

 

3. Generation of DC current

The electric current generated by the photovoltaic effect is in the form of direct current (DC). This DC current from the solar panels is used for the next step.

4. DC to AC through inverter Rs Conversion

Appliances used at home or in industries require alternating current (AC). An inverter is installed in the solar power system, which converts the DC current into AC current. An inverter is an important component of a solar power system.

5. Energy storage (storage facility)

Solar energy systems use energy storage devices such as batteries to store excess energy. These energy storage devices help to supply energy at night or during cloudy weather.

6. Energy consumption

AC current is delivered to the equipment from the inverter. This energy can be supplied to household appliances, industrial machines, pumps, and other essential items.

7. Energy Distribution

If the excess energy is not used, it is connected to the grid. In such cases, excess energy is supplied to the local electricity grid, thereby reducing the energy stress on the grid.

 

Advantages of solar energy

• Pollution-free and environment-friendly energy

• Facility of energy storage

• Less expensive

• Achieve autonomy

 

The functioning of the solar energy system is consistent and it is considered to be an environment-friendly and long-term energy source.

 

 

Main components of the solar energy system

1. Solar Panel

The most important component of a solar power system is the solar panel. These panels absorb sunlight and thereby generate electrical energy. Each solar panel contains photovoltaic (PV) cells, which convert photons from sunlight into electrical energy.

2. Inverter

The electric current generated by solar panels is in the form of direct current (DC). An inverter converts this current into alternating current (AC), which is used for household or industrial equipment. Inverter plays an important role in solar power systems.

 

 

3. Battery

A battery is used to store energy. This energy can be used at night or in cloudy weather. So the solar power system can work continuously efficiently.

4. Solar Charge Controller

A solar charge controller helps deliver the right amount of energy to the battery. These controllers protect the battery from overcharging and damage due to low voltage.

5. Mounting Structure

A mounting structure is used to mount the solar panels stably and at a proper angle. This structure is usually made of metal and the solar panels are mounted on its support so that the sunlight can be absorbed to the maximum extent.

6. Cables and Wires

Cables and wires are used to connect the various components of a solar power system. These cables need to be of high quality, as they carry the current properly.

7. Smart Meter

Smart meters are used in some solar power systems. These meters control energy generation and consumption. If excess energy is being sent to the grid, the smart meter registers it and ensures the correct proportion of the bill.

8. Monitoring and Maintenance System

Supervision and monitoring systems are used to monitor the performance of solar energy systems. It keeps a record of how much solar energy has been produced and how much energy has been used.

These components work together to make the solar energy system work coherently and efficiently.

 

Solar power projects are mainly of two types:

1. Photovoltaic Solar Power Plant

Photovoltaic solar power plants use photovoltaic (PV) technology to generate electrical energy directly from sunlight. This system consists of components like solar panels, inverters, batteries, etc. The main characteristic of photovoltaic projects is that they depend on the availability of direct sunlight and can be installed from small to large scale. The major types are as follows:

Grid-tied Solar Power Plant: This type of project is directly connected to the local electricity grid. If more energy is generated, it is sent to the grid, reducing electricity costs.

Off-grid Solar Power Plant: These plants are not connected to the grid and have integrated battery storage. It is used in remote or powerless areas.

 

Hybrid Solar Power Plant: Hybrid solar power plant uses a combination of solar power system and conventional power system. It also has battery storage, which can draw power from both the grid and batteries as needed.

2. Solar Thermal Power Project (Concentrated Solar Power – CSP)

In a solar thermal power plant (CSP), solar energy is first collected as heat without converting it directly into electrical energy and then generates electrical energy. In this method, mirrors are used to focus the sun's rays to a specific point. This creates a high temperature, which is used to generate steam, and this steam drives a turbine to generate electricity. Types of Solar Thermal Power Plant:

Parabolic Trough System: Sun rays are focused on a pipe using curved mirrors. The liquid in these pipes heats up to form steam, which generates energy.

Solar Tower System (Solar Tower System): In this system, the sun is reflected using multiple mirrors The light is focused on a tower. The liquid in the tower is heated to form steam, and this generates energy.

Dish Stirling System: In this, the sun's rays are concentrated at a point employing large dish-like mirrors. At this point, energy is generated by generating steam using a Stirling engine.

 

Also, there are other types of solar power plants:

Residential Solar Power System: A system that generates electricity by installing small solar panels on the roof of a house.

Commercial Solar Power System: A system installed on industrial and commercial buildings to meet large power needs.

 

Summary

Through these different types of solar power plants, electricity is generated in a low-cost, clean, and environment-friendly manner.

Firstly, the energy requirement is analyzed to determine the capacity of the solar energy system.

A suitable place to install the solar panels is chosen, such as the roof of a house, an open field, or a site on a factory building. Availability of sunlight throughout the day at the site is checked.

Site height, roof angle, and setbacks are monitored, as solar panels need to receive maximum sunlight.

2. System Design and Project Planning

The system is designed according to the power requirements. The number of solar panels, inverter capacity, and battery capacity are determined.

The angle and direction in which the solar panels will be installed is planned so that the panels receive maximum sunlight.

The total cost of the system, equipment required, and time required for installation are planned in detail.

3. Mounting of Solar Panels

A mounting structure is established, on which the solar panels will be securely mounted.

The mounting structure is strong and usually made of metal. This helps in fitting the panels at right angles and securely.

Solar panels are mounted on the structure at a certain angle and facing south, so that it gets maximum sunlight during the day.

4. Installation of Inverter

Direct current (DC) generated in solar panels is converted to alternating current (AC) by an inverter.

The inverter is mounted in a safe place, where it will be protected from sunlight and rain. The inverter is placed at a suitable distance from the panels and cables are used to connect to the panels.

5. Battery Installation

A battery is used to store solar energy. The battery is kept in a safe place in case it is needed.

If batteries are installed in a solar power system, power can be obtained even at night or in cloudy weather.

6. Wiring and Connectivity

Cables and wires needed for solar panels, inverters, batteries, and power distribution systems are connected.

The wiring process is done very carefully and following all electrical safety rules.

7. System Testing and Quality Check

 

After the installation is complete, the system is tested. All are checked to see if the solar panels are working properly, if the inverter converts DC to AC, and if the power distribution system is efficient.

All wires and connections are checked for safety.

 

8. Grid Connection

If the solar system is of the grid-tied type, it is connected to the local electricity grid.

Energy distribution is properly planned, so that excess energy can be sent to the grid and save electricity costs.

9. Training and Information

 

Users are trained on how the system works, what care to take, and what maintenance measures to take.

Also, guidance is given on the use of devices that provide information on electricity production and consumption, such as smart meters.

10. Maintenance and Monitoring

Regular maintenance is essential for the longevity of a solar power system. It is necessary to keep the panels clean, check the wires, maintain the inverter and battery.

All the components are checked periodically to keep the system working and maintain efficiency

This installation process is critical to keeping the solar power system operating efficiently and safely.

A financial calculation of a solar power project has to consider the total cost, savings, and return on investment (ROI). By doing this calculation, users can get an idea of ​​the long-term benefits of a solar project.

The process of financial calculation is as follows:

1. Initial Cost for Solar Project

• Solar Panels: The cost depends on the quality and capacity of the panels.

• Inverter: Capacity and quality of the inverter.

• Battery (if required): Battery cost based on storage capacity.

• Mounting Structure: The cost of installing the panels.

• Wiring and Cables: Cables required for secure wiring.

• Installation Cost: Labor cost to install the project.

• Licensing and other fees: Some locations require a permit for a solar project, so consider the fees.

 

 For example

That is, a typical installation of 1 kilowatt (kW) solar system can cost Rs 40,000 to 60,000.

 

2. Maintenance Costs

 

Maintenance of a solar plant can generally cost 1-2% per annum. This includes keeping panels clean, checking cables, checking inverters, etc.

For example, the annual maintenance cost for a 5 kW system may be around Rs 2,000 to 5,000.

 

3. Energy Savings and Production

To determine how many units (kWh) of electricity a solar panel can produce per day, the amount of sunlight received during an average day and the capacity of the panels are considered.

For example, a 5 kW solar plant can generate around 20-25 units of electricity per day. This system can provide 600-750 units of electricity per month.

These units are used to reduce electricity bills. That is, if the cost is Rs.8 per unit, by saving 750 units per month, the user can save Rs.6,000 (750 * 8).

 

4. Calculation of Return on Investment (ROI)

Total annual savings = monthly electricity savings * 12 months

Payback Period = Total Project Cost / Annual Savings

Usually the payback of a solar project can be achieved in 4-6 years. Once this return is obtained, only the electricity savings in the future and the project can turn into an income.

 

5. Subsidies and Financial Assistance

 

1. Solar projects are subsidized by the government in India and some other countries. This reduces the initial cost of the project.

2. Loan facilities for solar projects are also available from various banks.

3. Example Calculation: 5 kW Solar Project

4. Annual electricity savings: Rs 72,000 (Rs 6,000 per month).

5. Payback Period: 3,00,000 / 72,000 = 4.16 years.

 

A solar power plant can provide clean and low-cost electricity after the initial few years.
