How solar energy is produced?

Solar energy is created by nuclear fusion that takes place in the sun. Fusion occurs when the protons of hydrogen atoms collide violently in the nucleus of the sun and fuse together to create a helium atom. This process, known as the PP (proton-proton) chain reaction, emits an enormous amount of energy. The amount of sunlight that reaches the Earth's surface in an hour and a half is enough to manage the entire world's energy consumption for a whole year.

Solar technologies convert sunlight into electrical energy using photovoltaic (PV) panels or mirrors that concentrate solar radiation. This energy can be used to generate electricity or be stored in batteries or thermal storage. The photons that reach the solar cells and generate an electric current come from somewhere: the sun.

solar energy

is created by the constant nuclear fusion reactions that occur deep in the sun.

Nuclear fusion in the sun occurs when protons (which are essentially the same as hydrogen atoms) collide and fuse at extreme temperatures and pressures to create helium. This process emits a massive amount of energy (in addition to more protons), and in the center of the sun, this reaction occurs constantly, producing more than 500 million tons of hydrogen atoms per second.

Solar energy

is collected from the sun by photovoltaic cells. These free electrons are transferred to a positive terminal that sends those electrons to an electrical circuit where they cause electricity to flow through the wires as light and heat.

Solar power plants use large-scale solar thermal collectors for commercial heating of water or air on sunny days, so that they can be turned on when needed later in the day at night. Converts sunlight directly into electricity to power homes and businesses. Because you're still connected to your traditional power company, you can automatically draw additional electricity to supplement any solar power shortages off the grid. That said, the speed at which solar panels generate electricity varies depending on the amount of direct sunlight and the quality, size, number, and location of the panels in use.

Energy developers and utilities use solar photovoltaic and concentrating solar energy technologies to produce electricity on a large scale to power cities and small towns. Simply put, a solar panel works by generating electricity when particles in sunlight, or photons, release electrons from atoms and set them in motion. Similarly, solar-powered desalination units transform salt water into drinking water by converting energy from the Sun into heat, directly or indirectly, to drive the desalination process. This electric field forces the loose electrons to flow through the solar cell and out of the silicon junction, generating an electric current.

If you want to start saving money on electricity and investing in renewable energy, the first place to start is to compare prices for solar panel systems. The solar panels have an anti-reflective coating that increases the absorption of sunlight and provides the cells with maximum sun exposure. This photovoltaic load creates an electric current (specifically, direct current or DC), which is captured by the wiring of the solar panels.

The carbon footprint of solar panels is already quite small, since they last more than 25 years without loss of efficiency. The UK may not seem like the best country to generate energy from the sun, but solar energy only requires a certain level of natural light to harness the energy of the sun. Cadmium telluride and copper, indium and gallium diselenide are the two main semiconductor materials used in the production of thin-film solar panels. Concentrated solar thermal energy (CSP) systems use mirrors to reflect and concentrate sunlight on receivers that collect solar energy and convert it into heat, which can then be used to produce electricity or store for later use.

Utilities are also building large solar power plants to provide power to all grid-connected customers. In 1954, photovoltaic technology was born when Daryl Chapin, Calvin Fuller and Gerald Pearson developed the silicon photovoltaic cell at Bell Labs in 1954, the first solar cell capable of absorbing and converting enough solar energy into energy to run daily electrical equipment. . .
