Inside Solar Panels – How They Work

August 8, 2018

Have you ever driven by a home with solar panels or a roadside sign using solar power  and wondered how it all works? We often have clients (and neighbors of clients) approach our technicians and ask just that: “How does it all work?” For today’s blog, let’s take a look inside a solar panel system and see how it works. It really is fascinating.

 

According to Live Science online and our graphics on our website, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many smaller units called photovoltaic cells. Photovoltaic simply means they convert sunlight into electricity. Many cells linked together make up a solar panel. The electric current in the SunPower panels then flows to the inverter, which converts that DC electricity into AC, the most common form of electricity. Once the energy has been converted, it supplies energy to your home. Unused energy flows back into the grid for your area, and your home collects “credits”.

 

The photovoltaic (PV) cells in a solar panel are made of a special class of materials called semiconductors. Of all the semiconductor materials, silicon is most commonly used because of its availability (it’s the second-most abundant element in Earth’s crust). At SunPower by BlueSel we have the most advanced panels using Maxeon Technology®, which delivers unmatched reliability and higher efficiency than other conventional solar panels. SunPower panels capture more light and are more durable and efficient than any other solar panel in the industry.
