How Do Solar Panel System Work

Ac energy then flows through the home s electrical panel and is distributed accordingly.

How do solar panel system work. The more panels you deploy the more energy you generate. It s an idea that has been around for well over a century. The term solar panel is used colloquially for a photo voltaic module. Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass.

So if the grid shuts down so will your solar panels. A pv module is an assembly of photo voltaic cells mounted in a framework for installation. Solar panels work by letting photons released by the sun knock electrons free from atoms and thus generate a flow of electricity. The inverter runs to a smart meter that records the amount of energy you use and also the excess solar energy that is sent back to the utility.

1 over two to three decades average electric bill savings can amount to thousands of dollars. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect. Solar panels are composed of many smaller photovoltaic cells linked together. Solar panels actually comprise many smaller units.

Solar panels work by absorbing sunlight with photovoltaic cells generating direct current dc energy and then converting it to usable alternating current ac energy with the help of inverter technology. Photo voltaic cells use sunlight as a source of energy and generate direct current electricity. Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity. A collection of pv modules is called a pv panel and a system of panels is an array.

A solar provider handles the installation and then leases the equipment to you at a fixed monthly amount or sells you the electricity the panels generate at a set price per kilowatt hour. Those cells do the daily work of converting the sun s photons into electricity. In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight. Solar cells are made of silicon.

The other reason is that your solar panel system is connected to the grid via a solar inverter or grid tied solar. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. The most common application of solar energy collection outside agriculture i. When you really break them down a solar panel is nothing more than a big sheet of glass over a metal frame with a patch of wiring that runs to your home s main.

3 solar leases typically last 20 to 25 years. Every array is made up of several solar panels and every solar panel is made up of several solar cells. Arrays of a photovoltaic system supply solar electricity to electrical equipment.
