Solar Energy: The Key to Unlimited Power

SOLAR-ENERGY-THE-KEY-TO-UNLIMITED-POWER

Sun has been the ultimate source of light and energy. Yet, the powers of the sun have been overshadowed by the fossils fuels. Though the energy generated via these fossil fuels are helpful to mankind, they have hazardous effects on nature. As a result, the sea levels are rising, glaciers are melting, and the extreme weather is becoming a norm. But then luckily, the supply of fossil fuels are limited.

Since long, scientists were searching for a renewable energy resource that could replace fossil fuels.  The resource should be enough for everyone and must be easily accessible. It should also provide power without poisoning the earth. Now, finally, we have a solution, the Solar Energy.

The power of the Sun

The large magnitude of the solar energy makes it a rich and dependable source of energy. According to the United Nations Development Programme in its 2000 world energy assessment found that the annual potential of the solar system is 1,575- 49,837 exajoules. This is much higher than the total world energy consumption.

Solar Panels and Solar Cells
The solar energy can easily be converted into electricity which can then be used instead of other sources of electricity with the help of solar panels and solar cells. Solar panels and solar cells, both are the integral part of the solar energy system. Solar cells converts all the sunlight into electricity while the solar panels directs all of that energy output.

A single solar cell can only produce a limited amount of energy, so while building a solar energy system, multiple solar cells are connected in series or parallel circuits to create a solar module. These solar modules are then wired together to produce solar panels. These solar panels are then installed on the rooftops of the buildings.

How is Electricity Generated?
Both the solar cells and solar panels work together to produce electricity. The solar cells are made of silicon combined with other materials in such a way that there are extra electrons in one part of the cell and missing electrons in the other. When the sunlight strikes the cells, the photons present in the sunlight allows some of the electrons to break free and move towards the part with no electrons. These flow of electrons thus produces an electric current which is converted into electricity.

You can easily install solar panels on your rooftop and enjoy the benefits of the solar energy.
