| There are talks around the world about using solar | | | | ultimate source of energy that is renewable in every |
| energy as the means to fuel the economies. But is it | | | | sense too! So, methods to capture and transform |
| really possible? Before understanding what PV is, let | | | | solar energy into other types of energies like electricity |

| For thousands of years, animals and plants' remains | | | | Solar PV stands for Photovoltaic. |

| high temperature and pressure. The resultant as | | | | and then convert it into electric energy. The very name |
| known to humans was petroleum and coal. Now, we | | | | Photovoltaic implies the underlying principle as well as |
| know what it takes to produce the two main sources | | | | its working. PV generally consists of silicon |
| of energy, so, can you think of any way to reproduce | | | | semiconductor cells that are connected to each other. |
| them so that we can meet the daily requirements? No | | | | It is covered with glass for providing insulation. The |
| matter how advance we are or how many | | | | heat energy is an input for PV while electricity is the |
| improvements we see in our sciences, we can never | | | | output. This means that a solar panel take off the |

| The reason is clear; we can not wait for thousands of | | | | if you employ a solar PV or an array of PV at your |

| they are in a limited quantity on earth. So, this implies | | | | as solar PV can be manufactured and used |
| that sooner or later chances are that we will run out of | | | | anywhere on this earth. Finally, solar energy is |
| fuel! Can you imagine the world then? No electricity, | | | | completely free from poisonous or greenhouse gases |

| Fortunately the great thinkers of every country, | | | | and store electric energy for future usage as well. You |
