Lauded as the best alternative energy source for years, solar panels crown roadside signs and rooftops and help supply us with power. While the methodology behind solar panels is extremely precise, you don’t have to be a scientist to understand how they work.
So, how do solar panels work? Here we give you a step-by-step look at how solar panels work.
Sunlight Hits the Panel
Each individual panel comes with a metal frame, silicon cells, and casing surrounded by wiring and a special inverter. To maximize their use, the panels are arranged into an array and placed in a large outdoor space or rooftop. Also known as photovoltaic cells, the solar cells will absorb light during the day and store it.
Electric Current Is Produced
Solar panel cells are made up of thin semiconductor wafers and two layers of silicon. While one layer is negatively charged, the other is positively charged. When light energy strikes the solar panel cell, the cells energize and cause the electrons to disengage from the atoms. Once set into motion, those loose electrons will create an electric current.
Conversion of Electrical Energy
Although you now have solar panels working efficiently, the electricity produced is known as direct current (DC). Since this electricity can’t power homes directly, you must get an alternate current. Luckily, you can easily use an inverter to change DC electricity to AC. With modern systems, you can easily configure one inverter as individual micro-inverters attached to the system.
The Home Is Powered
Once converted, the solar energy will quickly be distributed to electrical power appliances. Since it works the same way as regular electricity, you don’t need to change anything in your home. More so, you are still connected to your power company and can supplement any shortages you may have in the grid.
Unused Energy Is Stored
During the day, when the sun is hot, you may collect more energy than you need for your home. With a smart electric meter, you can measure the energy flowing to and from your home. Any surplus energy will then be directed to your meter and stored. In certain states, you’re allowed to return any unused AC to the grid. This way, you will save a lot and avoid any wastage.
The Bottom Line
The benefits solar panel installation can bring to your business or home are endless. By installing solar panels, you’ll not only save money but the environment as well. A professional solar installer will tell you about the benefits so you can choose the right solution for your home. While the solar panel system is not rocket science, it’s definitely one of the best inventions.
