It is a great renewable energy because we will never run out of sunlight. You might have seen a solar panel on a calculator. Solar panels for homes is the same process but in a much bigger scale. Using solar energy can reduce or replace the use of fossil fuels.

Do you have solar panels, but not know how they work? Solar panels absorb sunlight and convert it into energy. It is a great renewable energy because we will never run out of sunlight. You might have seen a solar panel on a calculator. Solar panels for homes is the same process but in a much bigger scale. Using solar energy can reduce or replace the use of fossil fuels. Transforming sunlight into energy is a fascinating process.
A complicated process is involved when sunlight hits a photovoltaic cell (solar cell). A photovoltaic cell is made from a silicon atom mixed with a phosphorous atom. The outer shell of a phosphorous atom has 1 more electron then the silicon atom, and when sun hits the cell it takes a very small amount of energy to knock the extra electron free and find a hole to fill in. Then, the silicon atom is negative.
The next step in the process is the part where the energy is made. An electrical field is formed when the positive and negative silicon come together. The free electrons on the n side fill up a lot of the spaces on the p side. Whenever an electron goes to the p side it makes it harder for electrons to go to the p side. After some time, an electrical field is formed between the n and p side. The electrical field only lets electrons from the p side to the n side. This creates energy for us to use. That is the process of turning sunlight into energy.
There are advantages and disadvantages of having solar panels. One benefit of having solar panels is that they provide energy for your home. A disadvantage is that they are still very expensive, but when I interviewed Linda Tolliver Terry at Solar Works I found out that it’s cheaper than using fossil fuels. Another benefit is that it will reduce the use of fossil fuels. The next benefit is that a poor person that doesn’t know how to read and write can learn how to use solar power and help their community. There is a documentary movie about this called Solar Mamas by Jehane Nouiaim. Finally, another cost is that you often need to replace them and constantly check on them. Those are the main advantages and disadvantages of solar panels.
