How Do Grid-Tied Solar Panels Work?
Grid-tied solar panels harness the power of sunlight to generate electricity. These panels are equipped with photovoltaic cells that convert sunlight into direct current (DC) electricity. However, since most homes and businesses operate on alternating current (AC) electricity, an essential component of a grid-tied solar system is the grid-tie inverter.
The grid-tie inverter converts the DC electricity produced by the solar panels into AC electricity, which can be used to power your home or business. In addition, when the solar panels generate more electricity than is being consumed, the excess energy can be sent back to the grid. This process is made possible by net metering, which allows for the tracking of the electricity sent to the grid and may result in credits on your electricity bill.
Components of a Grid-Tied Solar System
A grid-tied solar system consists of several key components besides the solar panels and grid-tie inverter.
