What is solar energy?
Solar energy is the radiant energy emitted by the sun, which reaches Earth in the form of sunlight. This energy is incredibly powerful, with the sun releasing an estimated 384.6 joules (3.846×10^26 joules) of energy per second. To put this into perspective, this is more energy than the entire world consumes in a year. Let’s discuss how solar energy is helping environment:
1. Harnessing solar energy:
Humans have developed various technologies to harness and utilize solar energy. One of the most common methods is through the use of solar panels, also known as photovoltaic (PV) panels. These panels are made up of multiple photovoltaic cells, which are typically made from silicon. When sunlight hits these cells, it knocks electrons loose from their atoms, generating a flow of electricity.
2. Renewable and sustainable:
One of the key advantages of solar energy is that it is renewable and sustainable. Unlike fossil fuels, which are finite and non-renewable, solar energy is abundant and inexhaustible. The sun is expected to continue shining for billions of years, making solar energy a reliable source.
3. Environmentally friendly:
Solar energy is also environmentally friendly. Unlike fossil fuels, which release harmful greenhouse gases into the atmosphere when burned, solar energy produces no emissions. This means that using solar energy can help reduce our carbon footprint and mitigate the impact of climate change. 
How does solar power work?
Solar power works by capturing the sun’s energy using photovoltaic (PV) cells, which are typically made from silicon. When sunlight hits the PV cells, it knocks electrons loose from their atoms, generating a flow of electricity. Here are few things on how does solar power work:
1. Capturing solar energy:
Solar power is generated using photovoltaic (PV) cells, which are the building blocks of solar panels. These cells are made from materials, usually silicon, that exhibit the photovoltaic effect.
2. The photovoltaic effect:
The photovoltaic effect is the process by which certain materials, when exposed to sunlight, generate an electric current. This effect occurs because sunlight is composed of tiny particles called photons. When photons strike the surface of a PV cell, they transfer their energy to electrons in the material’s atoms.
3. Generating electricity:
When photons transfer energy to electrons in a PV cell, some electrons gain energy to break free from their atoms. These free electrons create an electric current when they move through the material. This flow of electrons is what we know as electricity.
4. Direct Current (DC) electricity:
The electricity generated by solar panels is in the form of direct current (DC). This type of electricity flows in one direction, from the solar panels to an inverter.
5. Inverter conversion:
Most appliances and electrical devices in homes and businesses use alternating current (AC) electricity. The DC electricity produced by solar panels must be converted into AC electricity using an inverter.
6. Grid connection and net metering:
In many cases, solar-powered homes and businesses are connected to the electrical grid. This allows them to use grid electricity when their solar panels are not generating enough power, such as during nighttime. Additionally, excess electricity generated by solar panels can be fed back into the grid, often earning the owner credits through a system called net metering.
7. Battery storage:
Some solar-powered systems include battery storage, allowing excess electricity generated during the day to be stored for use at night. This can increase the self-sufficiency of a solar-powered system and reduce reliance on the grid.
How do solar panels produce electricity?
Since we know how does solar power work let’s understand how do solar panels produce electricity through the photovoltaic effect. This process involves the conversion of sunlight into electricity using semiconducting materials such as silicon.
1. Photovoltaic (PV) effect:
Solar panels work based on a principle called the photovoltaic effect. This effect occurs when certain materials, known as semiconductors, are exposed to sunlight. Semiconductors are materials that can conduct electricity under some conditions but not others.
2. Composition of solar panels:
Solar panels are made up of many smaller units called solar cells, which are typically made of silicon, a semiconductor. Each solar cell contains two layers of silicon: an N-type layer, which has an abundance of electrons, and a P-type layer, which has an abundance of “holes” or places where electrons are missing.
3. Absorption of sunlight:
When sunlight hits the solar panel, it is absorbed by the silicon cells. The energy from the sunlight causes the electrons in the silicon to become excited and move from the valence band to the conduction band, creating an electric current.
4. Creation of electric field:
The movement of electrons creates a flow of electric current. The silicon in the solar cell is specially treated to create an electric field within the cell, which causes the electrons to flow in a specific direction, creating a direct current (DC) of electricity.
5. Collection of electricity:
Metal contacts on the top and bottom of the solar cell collect the electric current generated by the movement of electrons. This current is then transferred out of the solar panel to be used as electricity.
6. Conversion to alternating current (AC)
Most household appliances use alternating current (AC) electricity. Therefore, the direct current (DC) produced by the solar panel must be converted into AC using an inverter before it can be used in homes and businesses.
7. Net metering and grid connection
Many solar-powered systems are connected to the electrical grid. Excess electricity generated by the solar panels can be fed back into the grid, often earning the owner credits through a system called net metering. This allows solar-powered homes and businesses to use grid electricity when their panels are not producing enough power.
What solar panels do?
Solar panels play a crucial role in converting sunlight into usable electricity through a process called the photovoltaic effect. This effect occurs within the solar panel’s photovoltaic cells, which are typically made of silicon or other semiconducting materials.
When sunlight hits the solar panel, it excites the electrons in the semiconductor material, causing them to flow and create an electric current. This direct current (DC) electricity is then collected by metal contacts on the solar panel’s surface. Solar panels are often interconnected to form a solar array, which can generate a significant amount of electricity. This electricity can be used immediately to power appliances and devices in homes and businesses.
Excess electricity generated by solar panels store in batteries for later use for a credit. This process of net metering, allows solar panel owners to offset their electricity costs and contribute to a more sustainable energy future.
What’s the difference between solar PV panels and solar thermal panels?
The main difference between solar PV (photovoltaic) panels and solar thermal panels lies in how they harness solar energy and convert it into usable forms:
1. Solar PV panels:
- Function: Solar PV panels directly convert sunlight into electricity through the photovoltaic effect.
- Composition: They are made up of silicon or other semiconductor materials that generate electricity when exposed to sunlight.
- Usage: Solar PV panels are commonly used to generate electricity for residential, commercial, and industrial applications.
2. Solar thermal panels:
- Function: Solar thermal panels use sunlight to heat a fluid, such as water or oil, which is then used for various purposes.
- Composition: They typically consist of tubes or panels through which the fluid flows, absorbing heat from the sun.
- Usage: Solar thermal panels are often used for heating water in residential and commercial buildings, as well as for generating electricity through concentrated solar power (CSP) systems.
While solar PV panels directly convert sunlight into electricity, solar thermal panels use sunlight to heat a fluid, which can then be used for heating or electricity generation. Each type of panel has its own advantages and applications, depending on the specific energy needs and requirements.
How is solar energy produced?
