A solar panel is a device that is used to absorb energy from the sun to generate heat or in so many cases electricity. It is often called a photovoltaic cell free of cost . 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 as that the cells face the sun so as to enable maximum absorption of the sun rays. The greater the energy from the sun is, the more the electricity that is generated. Solar panels are used in many homesteads across the world this can many pros that are far more than cons. A few pros are discussed below.
One very important advantage of using solar panels is that it doesn’t emit any gases that are common in green houses. The panels do not emit any smoke, chemical or heavy metals which might be risk factors to human health. Solar panels are therefore environmental friendly when compared to burning of 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 creating ways to control global warming and the utilization of solar panels is most effective start. The solar panels therefore maintain a clean setting and they leave the air fresh. More importantly they help in 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 initiation of mutations in cells.
