What are Solar Panels?

All homeowners should know about solar panels and the generation of electrical power in the home. It is not difficult to find information about solar panels. An interesting fact about solar panels is that they are comprised of solar photovoltaic (PV) cells. Solar panel electrical systems employ photovoltaic cells to transmit energy from the sun to generate electricity used by household appliances, lighting, and other energy applications.

Facts About Solar Panels

Homeowners want to learn as much as possible about solar panels technology that will help them manage renewable energy resources more efficiently. The process of converting light (photons) to electricity (voltage) is termed the Photovoltaic ("PV") effect. Scientists employed with Bell Telephone learned that silicon exposed to sunlight produced an electrical charge. The PV effect was discovered in 1954. This is an important historical fact about solar panels. Homes and businesses are powered by individual solar PV systems. Utility companies depend upon PV technology to generate electricity for large power stations.
About Solar Panels

Photovoltaic (PV) Cells

Another interesting fact about solar panels is that photovoltaic cells are made from special materials such as silicon that is a semiconductor. A semiconductor uses an electric field or fields to allow electrons to flow freely in a designated direction after absorbed light energy has been transferred in the form of a current. The solar cell’s power occurs when the current and the voltage of a cell work together to produce electrical energy. The most important fact about solar panels is that a group of electrically connected photovoltaic (PV) cells forms modules that are packaged into a frame known as a solar panel. Each module will contain approximately 40 cells. These solar panels are then merged into large solar arrays.

More About Solar Panels for Your Home

Learning more about solar panels provides insight as to how solar panels are used to power homes and businesses. The main point to remember about solar panels is that each home will need approximately 10 to 20 solar panels to produce enough electrical power. Solar PV systems include solar panels, an inverter, charger and batteries.

Learning about solar panels and the way they work is essential. DC electricity produced by these modules is transmitted to the inverter. The inverter converts the DC power into AC electricity in addition to regulating battery charges. Clever homeowners know enough about solar panels to capture the renewable energy produced from the sun for use in their homes.
