How Solar Panels Work Basic

Our sun is a natural nuclear reactor.

How solar panels work basic.

Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity. Once your designer has worked out what string length to be used i e. You can buy equipment designed to mitigate this but it costs more. The more panels you deploy the more energy you generate.

How do solar panels produce electricity. Solar cells are sandwiches of conductive and semi conductive materials. Most solar cells are made up of silicon a semi conductor. How many solar panels can be placed in series the designer needs to work out how many of those strings can be placed in parallel to get the desired system size.

It releases tiny packets of energy called photons which travel the 149 6 million kilometres from the sun to earth in about 8 5 minutes. Solar panels are composed of many smaller photovoltaic cells linked together. Solar energy works by capturing the sun s energy and quietly and effectively turning it into electricity for your home or business. Thus in a solar cell semi conductive silicon is sandwiched between conductive materials.

How do solar panels work to generate electricity. Here is a list of the pv system basics. When solar panels are put to work in a parallel array their voltage stays the same but you add up their current. In its neutral state each silicon atom is connected to its neighbors by 4 strong.

Shade snow and other obstacles reduce the output of your solar panels. Pv panels which cost anywhere from 2 40 per watt to over 5 per watt are the single biggest expense of a pv system. Solar panels actually comprise many smaller units. If your panels don t get a lot of sun they won t work as efficiently as advertised.

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. Solar panels work by letting photons released by the sun knock electrons free from atoms and thus generate a flow of electricity. Their placement and mounting affect your system performance more than any other facet of the job. Now that we have a basic idea of the generation and flow of solar electricity let s take a deeper dive into the science behind the solar photovoltaic panel.
