How Are Solar Panels Made

It all starts with the raw material which in our case is sand.

How are solar panels made.

Photo voltaic cells use sunlight as a source of energy and generate direct current electricity. First silicon panels are generally made out of a semiconductor grade polysilicon. When light passes through these solar cells they set the electron present in them to move this effect is known as a photovoltaic effect. Solar panels consist of silicon cells connected in an array mounted on a rigid metal frame.

Solar cells are made out of silicon wafers. Now that we ve talked about the different ways panels can create electricity and the different kinds of panel materials let s look at how solar panels are made. How are solar panels produced. 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.

Solar panels contain cells of semiconductive material usually silicon usually encased in a metallic frame and tempered glass. Most solar panels are made of silicon. In fact it s the second most abundant element right behind oxygen on the planet. Hundreds of these rocks are being melted.

Thankfully silicon is a highly abundant resource. The silicon is collected usually in the form of solid rocks. The silicon in solar panels is manufactured through a reduction process in which the silica is heated with a carbon material and the oxygen is removed leaving behind purer metallurgical grade silicon. This flow travels in a circuit of wires that connect groups of solar panels called arrays.

The frames mostly made from aluminum provide the rigidness required to keep with the harsh environment. From there the grade must be further purified into polysilicon the solar grade purity of which is 99 999 percent. Solar pv modules top and two solar hot water panels bottom mounted on rooftops the term solar panel is used colloquially for a photo voltaic pv module. Purification is usually done with an electric furnace.

Those smaller squares are silicon solar cells and they link together in a series to form a circuit. A pv module is an assembly of photo voltaic cells mounted in a framework for installation. They re the ones that look like blue or black rectangular grids of smaller squares. When subject to sunlight photovoltaic cells create a flow of electric charge inside the solar panel due to the photoelectric effect.
