What is a solar panel?

Solar power starts with the sun. Solar panels (also known as “photovoltaic panels”) convert light energy from the sun into electricity that can be used to power devices.

Solar panels can be used in a variety of applications, including for telecommunications equipment, power banks, and of course, the generation of residential and commercial solar power systems.

Here we will discuss the history, technology and advantages of solar panels. We’ll learn how solar panels work, how they generate electricity, and where to buy the right ones.

The history of solar panels

In 1839, the French scientist Edmund Becquerel discovered the photovoltaic effect at the age of 19. He realized that when electrons are in an excited state in the conduction band, they can move freely through the material, creating an electric current. But this was not widely recognized until Einstein wrote a paper on solar energy, for which he eventually won the Nobel Prize in 1922. The first solar panel was invented in 1883 by Charles Fritz, who coated a very thin layer of gold on top of a thin layer of selenium. The conversion efficiency of the resulting cell was only about 1%. The invention sparked a movement to generate solar energy.(Source of this paragraph:https://ae-solar.com/history-of-solar-module/)

How do solar panels work?

Solar panels collect clean solar energy in the form of light, convert it into electricity, and then use it to provide electricity. A solar panel consists of several layers of silicon, phosphorous (giving the negative charge) and boron (giving the positive charge) stacked on top of each other. Solar panels work primarily because of the photovoltaic effect, the energy generated by sunlight hitting the surface of the solar panel, moving its electrons away from atomic orbits and releasing the energy into the electric field created by the solar cell, which then funnels these free electrons together up into a directional and stable current. This whole process is called the photovoltaic effect.

In a good grid-connected configuration, the solar system will generate electricity during the day and store that energy in batteries for use at night. Some areas allow solar system owners to sell a portion of the electricity they produce that exceeds what their homes need to use at night. Get paid (depending on local policy). In the actual use of most users, solar panels, solar inverters, controllers, and battery packs are all necessary accessories for normal use. The solar panels send DC power through the charge controller to the battery pack, which then extracts power from the battery pack to the inverter, which converts the DC current into AC power that can be used for non-DC appliances. The main function of the inverter is to improve the load capacity of the entire system.

Advantages of solar panels

The advantage of the solar panel is that it is an environmentally friendly and practical new energy source for sustainable development. With the deterioration of the global climate, we have been working hard to reduce the emission of harmful gases, so the use of solar power to replace the conventional power generation mode seems becomes even more important. A solar panel has no moving parts and requires little maintenance. Proper maintenance can make it last for over 30 years.

where can i buy solar panels and what is his price?

The price of solar panels started to drop a few years ago, but there is no demand and heat for it. So it’s a good thing for users.
