Solar Pv Panels How It Works

Solar photovoltaic cells are the building blocks of solar panels and any property owner can start generating free electricity from the sun with a solar panel installation.

Solar pv panels how it works.

The more panels you deploy the more energy you generate. The solar photovoltaic cells in your solar panels are the mechanisms which convert sunlight into energy. During the energy crisis in the 1970s photovoltaic technology gained recognition as a source of power for non space applications. Solar panels are composed of many smaller photovoltaic cells linked together.

The diagram above illustrates the operation of a basic photovoltaic cell also called a solar cell. Solar panels actually comprise many smaller units. A standard solar panel also known as a solar module consists of a layer of silicon cells a metal frame a glass casing and various wiring to allow current to flow from the silicon cells silicon atomic 14 on the periodic table is a nonmetal with conductive properties that allow it to absorb and convert sunlight into electricity. How does solar pv work.

When you install solar panels on your house the pv cells convert sunlight into direct current dc and an inverter connected to the system is what converts direct current into alternating current ac which is the type of current needed. In 1839 french scientist edmond becquerel discovered that certain materials would give off sparks of electricity when struck with sunlight. Install solar to start having photovoltaic cells work for you. It s an idea that has been around for well over a century.

A module is a group of cells connected electrically and packaged into a frame more commonly known as a solar panel which can then be grouped into larger solar. The solar cells that you see on calculators and satellites are also called photovoltaic pv cells which as the name implies photo meaning light and voltaic meaning electricity convert sunlight directly into electricity. The solar panels on the roofs of homes and businesses are referred to as solar photovoltaic but this is commonly shortened to pv because it s a bit of a mouthful it works by taking the rays from the sun and directing it through a solar panel which then gets transmitted to a solar inverter and then supplies your home in a. To see how solar works let s look at a typical pv system.

Solar panels work by letting photons released by the sun knock electrons free from atoms and thus generate a flow of electricity. Solar photovoltaic pv panels are based on a high tech but remarkably simple technology that converts sunlight directly to electricity.
