Have you ever wondered how solar panels work?
Solar panels work by converting sunlight into electricity through a process called the photovoltaic effect.
Here’s a simplified explanation of how solar panels work:
Photons from sunlight: When sunlight reaches the solar panels, it consists of tiny particles of energy called photons.
Absorption of photons: The PV cells within the solar panels absorb photons when they strike the semiconductor material, typically made of silicon.
Electron excitation: The absorbed photons transfer their energy to electrons in the semiconductor material. And then causing them to become excited and break free from their atomic bonds.
Electric current generation: The freed electrons are then directed through an electric field created within the PV cells. This field consists of built-in electric fields due to the structure of the PV cells. As the electrons move through this field, they create a flow of electric current.
Collection of electricity: The current generated by the PV cells is in the form of direct current (DC). It is collected by metal contacts on the surface of the solar panel and then transferred to an inverter.
Conversion to usable electricity: The inverter converts the DC electricity into alternating current (AC) electricity, which is the type of electricity used in homes and businesses.
Integration into the electrical system: The inverter produces AC electricity. Which can either directly power electrical devices within the building or be sent to the electrical grid for distribution.
