Solar Panel Basic Concept

Solar cell also called photovoltaic cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.

Solar panel basic concept.

Solar energy is created by nuclear fusion that takes place in the sun. The term solar panel is used colloquially for a photo voltaic module. Solar panels operate with a physical principle called the photoelectric effect. To understand these concepts a helpful analogy is to think of electricity like water in a tank.

The readeris told why pv cells work and how theyare made. In simple terms a solar cell generates a flow of electrons when it receives light and a free source of light such as the sun equals free energy. Solar energy is any type of energy generated by the sun. Fusion occurs when protons of hydrogen atoms violently collide in the sun s core and fuse to create a helium atom.

Photo voltaic cells use sunlight as a source of energy and generate direct current electricity. A collection of pv modules is called a pv panel and a system of panels is an array. A collection of panels in your system is called an array. The solar panel the first component of a electric solar energy system is a collection of individual silicon cells that generate electricity from sunlight.

In order to understand the rules of solar panel wiring it is necessary to understand a few key electrical terms particularly voltage current and power and how they relate to each other. The basic elements of photovoltaics theindividual electricity producing cell. First there are panels which collect the sunlight and turn it into electricity. The most common application of solar energy collection outside agriculture i.

When designing an array to power a load the maximum load is determined first and the array is designed to meet the needs of the load. Solar intertie photovoltaic pv systems are not particularly complex. A single solar cell produces only about 1 2 5 of a volt. Solar panel construction orientation and use page 28 of 31 battery panel.

Arrays of a photovoltaic system supply solar electricity to electrical equipment. Solar panels are made by laying out a grid of these cells on a protective backsheet and covering them with glass on the front. This process known as a pp proton proton chain reaction emits an enormous amount of energy. The photons light particles produce an electrical current as they strike the surface of the thin silicon wafers.

This process is complicated and there is software available to help the engineer to design a system. Chapters 6 8cover the designs of systems constructed from individual cells includingpossible. A pv module is an assembly of photo voltaic cells mounted in a framework for installation. These cells are arranged in solar panels which typically have a rated dc output of around 250 watts.
