Solar energy stands out as one of the most important technological advancements in the last 100 years. It involves converting sunlight into electricity using solar panels. If you’re considering a solar system, having a grasp of how this process works and the components involved can be beneficial.
Quick Guide to Solar Panel Production
Advancements in solar technology are ongoing, leading to more robust and efficient solar panels. Research and development in solar technology is a complex and competitive field. Let’s explore some fundamental principles of how solar panels work.
How Do Solar Panels Work?
Solar radiation, the light from the sun, is a potent form of energy, traveling 93 million miles to reach Earth in just 500 seconds. The U.S. Department of Energy estimates the sun’s energy can power the Earth for 90 minutes.
Solar panels contain photovoltaic cells that absorb the sun’s energy, similar to a car’s interior getting hot in the sun. Unlike a car, photovoltaic cells (PVs) use layers with positive and negative charges. When exposed to sunlight, an electric field activates the PV cell, pushing charged particles and creating an electric current.
The sun’s energy propels electrons from the layers of PV cells. These charged particles are then pushed along by a current, and the grid lines on solar panels enable the flow of electricity into the wiring in a home or office.
What Are Solar Panels Made Of?
The production of solar panels starts with silicon, a natural semiconductor found in sand. Semiconductors, like silicon, conduct electricity better than materials such as rubber or glass, though not as effectively as metals. This makes them ideal for electronic systems, handling current without overloading.
Silicon’s property makes it perfect for creating electric fields in photovoltaics. Solar cells made from silicon have been in use since the 1950s.
