Solar panels are something that everyone has heard of in recent times, and most people keep on wondering about the actual functioning of the solar panel that starts generating electricity as soon as it receives sunlight. If you are looking for the top solar companies in Perth for reliable service, Solarxcellence is the best solar company in Perth.
Here is how a solar panel works:
Composition of the solar panel
Glass, fiber, aluminium, copper, and silicon are used to make solar panels. Silicon is the major component that is responsible and can generate electricity from solar rays. Silicon is a semiconductor material made by mixing sand with carbon and processing it at a temperature of 2000 degrees.
To make electricity from silicon; aluminium and phosphorus are doped in it. As you may know, phosphorus has 5 electrons in its outermost orbit, and aluminium has 3 electrons in its outermost orbit. Silicon is divided into two parts, P(positive) type silicon in which electrons are not much. The second N-type means negative, in which there is an excess of electrons.
The P and N layers are made inside the solar panel. When N-type silicon is heated, electrons start flowing through it. The particles of energy found in the light emanating from the sun are called "photons." Receiving photons in the form of heat or electricity is called "solar energy." Due to this, the solar panel starts generating electricity.
Batteries
If you want to use the electricity generated from the solar panel at night, then a battery is required, in which the electricity generated by the solar panel can be collected. Solar panels stop generating electricity due to a lack of sunlight, so the collected energy in these batteries is used to run electrical appliances.
How many types of solar panels are there?
There are many types of solar panels, namely polycrystalline solar panels, monocrystalline solar panels, thin-film solar panels, and half-cut solar panels. But mainly, solar panels are divided into two parts: Poly and Mono:-
Polycrystalline solar panels are cheap. Instead of using a single crystal of silicon, different crystals are used in their manufacturing. These solar panels are useful for ordinary use, but their efficiency is less than that of monocrystalline panels. Polycrystalline cells are blue because of the way sunlight reflects off the crystals.
Monocrystalline solar panels are the oldest and most developed of the various types of solar panels. These monocrystalline solar panels are made up of approximately 40 monocrystalline solar cells. These solar cells are made of pure silicon.
The best solar panels depend on the purpose of the panels and where they will be installed. For residential properties with large roof spaces or properties, the best choice of panels may be polycrystalline. Polycrystalline panels are the most economical for large spaces and will provide adequate efficiency and power. For residential properties with smaller spaces, monocrystalline solar panels may be the best option. These panels work well for people who want to get the most energy out of a small space. Monocrystalline solar panels and polycrystalline solar panels are suitable for homes and other similar buildings. Solarexcellence is one of the best solar companies in Perth.
