How Solar Panels Produce Electricity

To produce the maximum amount of power per square foot a solar panel has to be well designed to handle temperature spectrum angle and amount of light.

How solar panels produce electricity.

Eventually fossil fuels a non renewable energy source will be depleted and the world will have to turn toward renewable energy sources like solar and wind power. This all happens as light hits a unit called a photovoltaic cell. Electricity generation solar radiation may be converted directly into electricity by solar cells photovoltaic cells. Solar panels work by allowing particles of light called photons to knock electrons from their atomic orbitals.

Inside each solar panel is a conductive metal plate connected to wires that lead to a fused array combiner. Unlike fossil fuels solar energy is an infinitely renewable energy source. Some people associate solar power with heat because heat is associated with lots of sunlight but if there s too much heat your solar panels may not work as effectively. Energy from the array is sent through an inverter which transforms the initial direct electrical current into the alternating electrical current required to power human made structures.

In such cells a small electric voltage is generated when light strikes the junction between a metal and a semiconductor such as silicon or the junction between two different semiconductors. All solar panels are rated by the amount of dc direct current power they produce under standard test conditions. When this occurs a flow of electricity is generated and this electricity is harnessed and preserved as electrical energy. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect.

Solar panels use photovoltaic cells to produce electricity according to the united states department of energy.
