A solar panel is a device that is used to absorb energy from the sun in order to generate heat or in many cases electricity. It is also referred to as a photovoltaic cell since it is made of many cells that are used to convert the light from the sun into electricity.
The only raw material for these solar panels is the sun. it is made in such a way that the cells face the sun in order to enable maximum absorption of the sun's rays.

The greater the energy from the sun the more electricity that is generated. Solar panels are used in many homesteads in the world due to their many pros that are far more than cons. Some of these pros are discussed below.
One very important advantage of using solar panels is that they do not emit any gases that are common in greenhouses. The panels do not emit any smoke, chemicals or heavy metals that can be risk factors for human health. Solar panels are therefore environmentally friendly when compared to burning fossil fuels to generate energy.
This is very important since carbon emissions are dangerous and avoiding their emission helps in safeguarding our present and future environment. Being environment-friendly is important since the government is constantly coming up with ways to control global warming and the use of solar panels is a great way to start. The solar panels, therefore, maintain a clean setting and they leave the air fresh.
More importantly, they help in the prevention of many cancer incidences. This is because some products from some sources of energy like nuclear energy have been said to cause cancer due to the initiation of mutations in cells.
Secondly, the use of solar panels ensures on-going free energy for those who use it. This is mainly because the only cost incurred is that of installation.
Once the installation has been done the energy is free since the panel does not require regular maintenance or fuel to run it. It also requires no raw materials for its operation. It works as long as there are sun rays which is an everyday thing in most parts of the world. In a world where equal distribution of resources is continuously being sought, this is very important since each and everyone has equal rights when it comes to using solar energy.
