How do solar panels work?


Solar panels work by harnessing the power of sunlight to generate electricity. They are made up of individual solar cells, usually composed of silicon, which convert sunlight into direct current (DC) electricity. Here's a step-by-step explanation of how solar panels work:

Sunlight hits the solar panels: When sunlight shines on the solar panels, it contains tiny packets of energy called photons.

Photons are absorbed: The solar cells in the panels are designed to absorb photons from sunlight. As the photons are absorbed, they transfer their energy to the electrons in the atoms of the solar cells.

Electron movement: The energy from the photons causes the electrons to break free from their atoms, creating a flow of electrons.

Electric field creation: The solar cells are constructed with an electric field, which acts as a built-in diode. This electric field forces the free electrons to move in a specific direction, creating a flow of electricity.

Current generation: As the electrons flow in a single direction, they create an electric current. This current is in the form of direct current (DC), which is the type of electricity that solar panels produce.

Conversion to usable electricity: Since most homes and businesses use alternating current (AC) electricity, the DC electricity produced by solar panels is converted into AC using an inverter. The inverter transforms the DC electricity into AC electricity, which can be used to power your appliances and home.

Energy consumption or storage: The AC electricity produced by the solar panels can be consumed instantly, powering your electrical devices and reducing your reliance on the grid. Alternatively, if you have a solar battery storage system, excess energy can be stored for later use when the sun isn't shining.

By converting sunlight into electricity, solar panels offer a clean and renewable energy solution, helping to reduce your carbon footprint and lower your electricity costs over time.
