This is due to the potential savings on electricity bills and the environmental benefits associated with solar energy. Additionally, as more people become environmentally conscious, solar-powered homes are becoming increasingly attractive to potential buyers.
How Solar Panels Work
Now that we understand the benefits of solar energy for homes let’s dive into how solar panels actually work.
Solar panels are made up of numerous photovoltaic (PV) cells, also known as solar cells. These cells are connected and mounted onto a frame, which is usually placed on the roof of a home. The PV cells are made up of layers of silicon, a semiconductor material that can absorb photons (light particles) from sunlight.
When sunlight strikes the PV cells, it dislodges electrons from the atoms within the silicon layers. These electrons then flow through the cell, creating a direct current (DC) of electricity. An inverter then converts this DC electricity into alternating current (AC), which is used to power household appliances and electronics.
The amount of electricity generated by solar panels depends on several factors, including the number of panels, their efficiency, and the amount of sunlight available. On average, a typical home in the United States can generate enough solar energy to cover 86% of its annual electricity needs.
