How Are Solar Panels Designed

Solar panels actually comprise many smaller units.

How are solar panels designed.

All solar panels are rated by the amount of dc direct current power they produce under standard test conditions. 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. Solar photovoltaic system or solar power system is one of renewable energy system which uses pv modules to convert sunlight into electricity. 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. First there s the panel itself. Solar panels consist of silicon cells connected in an array mounted on a rigid metal frame. Solar panel output is expressed in units of watts w and represents the panel s theoretical power production under ideal sunlight and temperature conditions.

When light passes through these solar cells they set the electron present in them to move this effect is known as a photovoltaic effect. The large black solar panels you see on homes and businesses are made of a bunch of solar cells or photovoltaic cells made of silicon semiconductors that absorb sunlight and create an electric current. In turn one or more of these modules may be wired and framed together to form a solar panel. These individual cells are connected together to make one solar panel.

The electricity generated can be either stored or used directly fed back into grid line or combined with one or more other electricity generators or more renewable energy source. Each rectangular matrix is laminated onto glass and quickly becomes a larger panel. A solar or photovoltaic pv module generally consists of 36 interconnected cells laminated to glass within an aluminum frame.
