How Solar Energy's are Converted to Electricity?

Introduction

Actually, by solar cells we can change sunlight to electricity directly. Every day, the light of sun hits your roof's solar panels with photons (sunlight particles). These photons are converted by solar panel into electrons of direct current (DC) electricity. The electrons flow out of the solar panel into an inverter and other electrical safety devices. The function of an inverter is to convert the "DC" power (which commonly used in batteries) into an alternating current or "AC" power. AC is a kind of electrical power that computer, television and toasters use when plugged into wall outlet.

The solar energy is one of the most important energy on the world because it is totally free, available widely, produces no pollution, no emission, no noise and no carbon footprint. so we must use this energy us can us possible to avoid the effect of other energy .

The solar power systems that are used in our roof, produce the power directly from the sunlight's. Each solar cell in the panels convert the sunlight's directly into electricity. In fact, there are many factors which affect how well cells do that.

How solar energy's are converted to electricity?

Solar cells are made of a mixture of silicon and other elements in such way that there are extra electrons in one part of the solar cell and missing electrons in the other part of the solar cell.

When sunlight's hit these cells, the extra electrons are loose from the silicon due to the photons in the light, and they will flow to the part of missing electrons. This flow of electrons will produce an electrical current that finally reaches the inverter, where it converted into usable electricity.

The producing of electricity from solar energy affecting by many factors and the most fundamental factors is cell's orientation.

In the northern half of earth, the best results of converting solar energy into electricity can be when the cells facing south, also when the cells facing east or west can still produce power but for a shorter period of time.

There are some systems employ trackers that turn solar cells to face the sun directly as it moves across sky, so the amount of electricity produced will increase. However, it introduce more complicated moving parts into the system that need more maintenance and repair from time to time.

Nowadays many activates work by solar energy because of these advantages :
