What do transformers convert in a photovoltaic system?

In a photovoltaic system, transformers primarily serve the purpose of adjusting voltage levels to ensure efficient transmission and compatibility with the electrical grid. When it comes to the role of transformers, they are designed to step up the voltage to allow electricity generated by solar panels to be transmitted over long distances with reduced losses.

Specifically, transformers convert high voltage low current to low voltage high current as the electricity is being conditioned for use by residential or commercial applications. This conversion is crucial because while solar panels generate power at lower voltages, the transmission of electricity is more efficient at higher voltages due to reduced resistive losses.

Thus, transformers enable the electricity produced by the solar array to be utilized effectively, ensuring that it can meet the requirements of various applications once it reaches its destination. This function is fundamental in the integration of solar power into the electrical grid and maximizing the energy transmission efficiency from solar farms to end users.
