How solar panels work
If you are thinking about having solar roof panels fitted, then you may wish to know how solar panels work.
Solar panels are made up of solar cells that have been constructed together to form the panels. Solar cells consist of many thin layers of silicon and as the sunlight strikes, electrons within each solar cell are dislodged. The freed electrons can then only return through an external circuit, causing electricity to flow.
The electrical energy generated is a Direct Current (DC), which is then transferred into an Alternating Current (AC) by an inverter and is then either used in the home or exported to the National Grid.
Because sunlight is present even when the sky is overcast, photovoltaic solar panels will produce electricity whatever the weather. However, the stronger the sunlight, the more electricity will be produced at any one time.
This process of converting light from the sun into usable electrical energy is a photovoltaic process. Solar panel systems are also known as photovoltaic syatems, so by knowing how solar panels work you know how solar photovoltaic systems work.
