Generating solar power

Solar power can be generated by converting sunlight into electricity. This electricity can be put to several domestic and industrial uses. Solar power can be used in both rural and urban areas to meet the power demands. As an important and renewable source of power, it can be used in the future as well to generate massive amounts of electricity.

Solar panels can be used for generating solar power. A solar panel is made up of a number of individual solar cells. Solar cells are also called photovoltaic cells that can convert sunlight into electric current.

Solar panels are usually installed on roof tops where there is sufficient amount of sunlight. This helps the solar panels to generate more solar power because more sunlight can be captured.

Solar energy falls on the solar cells of the solar panel. This results in electron movement in the solar cells and an electric current gets generated because of the two different charges that generated inside the cells. The electric current is collected by a charge controller which controls the amount of electric current being supplied to the batteries. In the batteries, the electric current can be used directly for direct power in the form of direct current. The direct current can also be converted to alternating current by an inverter for alternating power supply.

The amount of solar power generated by solar panels depends upon the amount of sunlight received. Currently, only a small fraction of the total solar power generated is being used in the world. New methods have to be devised so that solar power can be used to its full potential.
