Explain How Solar Panels Are Manufactured

The makeup of monocrystalline silicon is similar to that used inside of computer chips.

Explain how solar panels are manufactured.

Solar panels actually comprise many smaller units. A pv module is an assembly of photo voltaic cells mounted in a framework for installation. We ll look at the manufacturing process for most common panels photovoltaic or pv. The term solar panel is used colloquially for a photo voltaic pv module.

Once the loose electrons hit metal plates the current is then directed into wires allowing the electrons to flow like they would in any other source of electric generation step 2 in our process. A collection of pv modules is called a pv panel and a system of panels is an array. Monocrystalline silicon panels are made of a mixture of silicon and crystalline seed. Solar cells are made out of silicon wafers.

Manufacturers pour this mixture into layers until they have enough layers for individual panels. Solar panels are comprised of several individual solar cells which are themselves composed of layers of silicon phosphorous which provides the negative charge and boron which provides the positive charge. These are made out of the element silicon a hard and brittle crystalline solid that is the second most abundant element in the earth s crust after. Simply put a solar panel works by allowing photons or particles of light to knock electrons free from atoms generating a flow of electricity.

Basically they do this by enabling light particles from the sun to knock electrons from atoms in the pv cells. Each rectangular matrix is laminated onto glass and quickly becomes a larger panel. Mono crystalline silicon cells are more efficient than polycrystalline or amorphous solar cells. According to solar world a leading manufacturer of solar panels its process involves soldering six strings of ten cells each making a rectangle of 60 cells.

Monocrystalline solar panels are produced from one large silicon block and are produced in silicon wafer formats. This flow is known as an energy current and the strength of the current determines how much electricity each cell can produce. Photo voltaic cells use sunlight as a source of energy and generate direct current electricity. Solar panels absorb the photons and in doing so initiate an electric current.

While most solar panel manufacturers offer a ten year materials warranty rec provides a maximum of 20 year warranty against any defects in their solar panels. Photovoltaic cells make electricity from sunlight. As the solar panel generates an electric current the energy flows through a series of wires to an inverter see step 3 above. First the cells must be put together to form a big sheet.
