How Does Solar Power Work? – Step by Step Guide

Solar power works by converting the sun's energy into electricity. There are two types of energy that the sun produces for our use: electricity and heat. Both are produced using solar panels, which range in size from residential rooftops to "solar farms" that span acres of rural land.

The amount of sunlight falling on the earth's surface in an hour and a half would be enough to supply the earth's energy for a full year. Solar technology converts sunlight into electrical energy through photovoltaics (PV) or through mirrors that concentrate solar radiation. This energy can be used to generate electricity or stored in batteries or power storage.

• Solar Energy 101

Solar radiation is light, also called electromagnetic radiation, emitted by the sun. Although every part of the world receives some amount of sunlight throughout the year, the amount of radiation that reaches every part of the world varies. Solar technology captures this radiation and converts it into a useful form of energy. There are two main types of solar energy technology: photovoltaics (PV) and solar thermal power (CSP).


• Basic Concepts in Photovoltaics

You are probably familiar with PV, which is used in space. When the sun shines in the sky, the energy from the sunlight is concentrated in the photovoltaic cells in the panel. This force creates an electrical charge that moves in response to the electrical current inside the cell, causing electricity to flow. 

• The Basic Principles of Solar Thermal Energy are Based

A solar thermal system (CSP) uses mirrors to deflect and focus sunlight on receivers that collect the sun's energy and convert it into heat, which can be used for electricity or storage. for use. It is often used in large power plants.

• The Basics of System Integration

Solar energy technology does not stop at the production of electricity through PV or CSP systems. These solar power systems will be integrated into existing residential, commercial and power grids with a diverse mix of traditional energy sources and renewable energy sources.


• The Basis of Emergency Payments

The amount of non-material costs, known as soft costs, also affects the cost of solar energy. These costs include licensing, financing, and installing solar power, as well as the costs that solar companies incur to acquire new customers, pay suppliers, and cover their bottom line. For rooftop solar power systems, indirect costs account for the largest cost loss.


• Basics of Solar Energy

Solar energy can help reduce the cost of electricity, contribute to a flexible energy grid, create jobs and promote economic growth, create backup power for nights and outages when combined with security, and operate works well in small and large scale.


• Fundamentals of Solar Industry

Solar power systems come in all shapes and sizes. Rooftop systems are found across the United States, and businesses are choosing to install solar panels. Utilities are also building large solar power plants to provide electricity to all connected customers.


Is solar Energy a Clean Source of Energy?

Yes, solar energy is an infinite renewable energy that produces harmful greenhouse gases - as long as the sun continues to shine, energy will be released.

The carbon footprint of solar panels is already low, lasting more than 25 years. In addition, the materials used in the panels are recycled, so the carbon footprint will continue to decrease.

When was Solar Energy Discovered?

Man has used solar energy since the 7th century BC. when humans used sunlight to start fire by reflecting the sun's rays on shiny objects. Later, in the third century BC, the Greeks and Romans used mirrors to illuminate the sun's power for religious ceremonies.

In 1839 and only 19 years old, the French physicist Edmond Becquerel discovered the photovoltaic effect (PV) by testing a cell of metal electrodes in a conducting solution. He said that the cell produces more electricity than the light - it is a photovoltaic cell.

In 1954, PV technology began when Daryl Chapin, Calvin Fuller and Gerald Pearson developed the silicon PV cell at Bell Labs in 1954 - the first solar cell capable of absorbing and converting enough solar energy into energy to power electrical equipment. work every day. Today, satellites, spacecraft orbiting the earth, are powered by solar energy.


How is Electricity Produced Directly from Solar Energy?

Silicon or other semiconductor material is usually embedded in a metal panel with a glass cover. When this material is exposed to a photon of sunlight (a small packet of energy), it releases electrons and creates an electrical charge.

The PV charge produces electricity (more direct, direct current or DC), which is picked up by the wiring of the solar panel. This DC electricity is converted into alternating current (AC) by an inverter. Another option is the type of electrical outlet used when you plug the device into a normal wall outlet.


What is the Difference Between Photovoltaic Panels and Solar Panels?

Photovoltaic panels produce electricity, as explained above, while solar panels produce heat. Although the source of energy is the same - the sun - the technology of each system is different.

Solar PV is based on the photovoltaic effect, in which photons (which are basically light) impact the surface of a semiconductor such as silicon and produce the release of electrons. Solar power is not very sophisticated and simply heats water (or other water) by sunlight. For domestic use, solar panels are also installed on the roof facing the sun, heating the water stored in the hot water tank and thus providing hot water and heating. On a larger scale, solar thermal can also be used in power plants.


What is a Solar Farm?

A solar farm, also known as a solar farm or solar farm, is a large tract of land with interconnected solar panels that are placed together over several acres, to produce large amounts of solar energy at the same time. Solar farms are designed for large amounts of solar energy that feed directly into the grid, as opposed to individual solar panels powering a single home or building.


Can Solar Energy be Generated on a Cloudy Day?

Yes, it is possible - solar energy only needs a certain level of daylight to generate solar energy. That said, the number of solar panels that produce electricity varies depending on the exact amount of sunlight and the quality, size, number and location of the panels used.


Who are the Biggest Producers of Solar Energy in the World?

By 2022, China will be the largest producer of electricity in the world. The United States is in second place, followed by Japan, Germany and India.


How can we Introduce More Solar Energy into our Electrical System?

The UK and US governments aim to decentralize their electricity systems by 2035, in which renewable energy sources such as solar power is expected to play a major role.
