Solar panels are a clean and renewable way to generateelectricity. They work by converting sunlight into electricity through the photovoltaic effect. This effect occurs when photons from sunlight strike a semiconductor material, such as silicon, and knock electrons loose from their atoms. These free electrons then flow through the material, creating an electric current.
The basic building block of a solar systems is a solar cell. Solar cells are made up of two layers of semiconductor material, typically silicon. The top layer is doped with phosphorus, which makes it have an excess of electrons. The bottom layer is doped with boron, which makes it have a deficiency of electrons. This creates a built-in electric field across the solar cell.
When photons from sunlight strike the solar cell, they excitethe electrons in the top layer. These excited electrons can then move across the electric field to the bottom layer, where they recombine with holes. This recombination process releases energy, which is used to create an electric current.
The amount of electricity that a solar cell can generate dependson the amount of sunlight that it receives. The efficiency of a solar cell is the percentage of sunlight that is converted into electricity. The efficiency of solar cells has been steadily increasing in recent years, and commercially available solar cells are now typically about 20% efficient.
Solar panels are typically made up of a large number of solar cells connected together in series. This increases the voltage of the solar panel, which makes it more efficient at generating electricity. Solar panels are also often connected to an inverter, which converts the direct current (DC) electricity produced by the solar cells into alternating current (AC) electricity, which is the type of electricity that is used in homes and businesses.

Solar panels are a clean and renewable source of energy that can help to reduce our reliance on fossil fuels. They are also a relatively affordable option, and the cost of solar panels has been declining in recent years. As the cost of solar panels continues to decline, they are becoming a more attractive option for homeowners and businesses. Battery Storage
