The energy within the dazzling ball of fire is harnessed by almost all the major parts of the worldto replace the conventional methods of energy production. It can be used to power the machines and electrical circuitry at home or business establishments. Photons are released by the sun which travels at high speed along the track of 93 million miles in about 8.5 minutes. Sufficient photons enter our planet to generate enough energy to satisfy the needs of the population for a whole year. In the United States, only half of one per cent of the energy consumed is contributed by photovoltaic power. But the case seems to take a rise in the coming years with many countries having plans to shift to solar energy to power their major electric structures.


With the rapidly dropping cost of harnessing solar energy and the improving technology with every passing day, our ability to use the abundance of light is on the rise. Let us have a closer look at how the solar panels work.

How Does the Solar Panel Work?

Several solar cells constitute the photovoltaic solar cells that are installed at your house. These solar cells are made of silicon in the form of semiconductors. A positive and a negative layer are infused into the compound structure to create an electric field, like in a battery.


Imagine the roof of your house where the solar panel is installed; sunlight hits directly on the topmost portion of the structure. When the light enters the panel, the energy generated within the solar panel is converted to DC. This current then flows to an inverter where the electricity gets converted from DC to AC, and this electricity can be used to power your house. The working is as simple as that, and the panels are highly efficient and affordable, thereby making it the alternative power generation technique that people prefer to employ at their house. There is no better form of energy to be generated in domestic settings with such a straightforward process to make it appealing to everyone.

But what baffles most people is the feature of solar panels which they consider as a drawback. The questions that arise are that of the electricity production when the house is unoccupied and also the break in generation caused at night without sunlight to activate the panels. Such concerns are resolved through the benefit that the consumers are provided in the form of a system called “net metering.”

The system works in such a way that the energy produced by the panels would be much more than the required amount. When this occurs, the excess power created gets transferred to the grid that is located elsewhere. Every consumer will get a credit for the energy that they feed the grid with, which they can use to draw energy from conventional grids at night and on cloudy days. The net metering system records the excess energy that is sent from your house, and it is compared to the power you receive from the grid.
