How Do Solar Panels Turn The Sun Energy Into Electricity

Photovoltaic technology directly converts light from the sun into electricity.

How do solar panels turn the sun energy into electricity.

But how do solar panels do this. Just like a sandwich it s the. To understand this process further let s look at the solar energy components that make up a complete solar power system. Solar powered photovoltaic pv panels convert the sun s rays into electricity by exciting electrons in silicon cells using the photons of light from the sun.

As soon as the light is removed the solar cell stops. A solar cell is made from two layers of silicon one doped with a tiny amount of added phosphorus n type. Solar cells are what make collecting solar energy possible. N for negative the other with a tiny amount of boron p type.

They are attached by wire to a circuit. P for positive the doping ingredients create extra electrons in the n type layer and holes missing electrons in the p type layer. The bread on either side consists of thin strips of metallic electrodes. They extract the power generated within the solar cell and conduct it to an external circuit.

A solar panel is a semi conductor device which will produce an electrical voltage and current if light falls on it. With this energy system the solar energy from the sun is converted into electricity by using an intermediate circuit photo voltaic. In all reality it s actually quite simple. Solar changes that by harnessing just a small percentage of the mind boggling amount of energy with which our sun pummels the earth and converting it into usable power.

Strikes the semiconductor light is converted into electricity that flows through the circuit. An active solar energy source has two major applications. In most solar systems solar panels are placed on the roof. They can do this because of something called the photovoltaic effect.

It is actually a giant diode a one way valve for electricity and when light falls on it this gives some electrons enough energy to jump through the valve and the only way they can get back is to flow around the circuit doing useful work. This electricity can then be used to supply renewable energy to your home or business. And the solar panels that you see on an increasing number of roofs do something similar converting light into electricity. What s in a solar cell.

It s used on the solar panels that adorn rooftops cars calculators and even planes. On its own a single.
