Solar panel basic concept.

A single solar cell produces only about 1 2 5 of a volt. 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. The dc signals are fed into an inverter which converts the dc into grid compatible ac power which is what you use in your home. A collection of pv modules is called a pv panel and a system of panels is an array.

This process is complicated and there is software available to help the engineer to design a system. First there are panels which collect the sunlight and turn it into electricity. It takes multiple panels to provide power to a typical home or office. Arrays of a photovoltaic system supply solar electricity to electrical equipment.

The solar panel the first component of a electric solar energy system is a collection of individual silicon cells that generate electricity from sunlight. Solar panel construction orientation and use page 28 of 31 battery panel. Solar panels are made by laying out a grid of these cells on a protective backsheet and covering them with glass on the front. 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.

Photo voltaic cells use sunlight as a source of energy and generate direct current electricity. The most common application of solar energy collection outside agriculture i. 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. The photons light particles produce an electrical current as they strike the surface of the thin silicon wafers.

Solar energy is created by nuclear fusion that takes place in the sun. Solar intertie photovoltaic pv systems are not particularly complex. A pv module is an assembly of photo voltaic cells mounted in a framework for installation. The readeris told why pv cells work and how theyare made.

To understand these concepts a helpful analogy is to think of electricity like water in a tank. Fusion occurs when protons of hydrogen atoms violently collide in the sun s core and fuse to create a helium atom. Thereis also a chapter on advanced types of silicon cells. Solar energy is any type of energy generated by the sun.

The term solar panel is used colloquially for a photo voltaic module. This process known as a pp proton proton chain reaction emits an enormous amount of energy. The basic elements of photovoltaics theindividual electricity producing cell. Solar cell also called photovoltaic cell any device that directly converts the energy of light into electrical energy through the photovoltaic effect.
