How Does a Solar Inverter Work?

A solar inverter operates by converting the variable DC output generated by solar panels into AC output, which is the type of electricity used in homes and businesses. Let me take you through the mechanism of a solar inverter:

  1. Sunlight Absorption: When sunlight shines on the solar panels, semiconductor layers within the panels absorb the light and generate a flow of electric current.
  2. Direct Current (DC): The electric current produced is in the form of DC, which consists of a constant flow of electrons in one direction. This DC output can be stored in a battery for later use or sent directly to the inverter.
  3. Solar Inverter Conversion: The inverter plays a crucial role in converting the DC electricity into AC electricity. By running the DC output through a transformer, the inverter transforms it from DC to AC, making it compatible with the appliances, devices, and electrical grid that rely on AC power.

Through this conversion process, a solar inverter ensures that the solar-generated electricity is in a form that can be used to power homes, businesses, and other electrical systems.
