On-grid systems typically consist of solar panels, an inverter, and a bi-directional meter, enabling users to power their properties with solar energy, feed excess electricity back to the grid, and draw from the grid when needed. This fact sheet illustrates the roles of distributed and centralized renewable energy technologies, particularly solar power, and how they will contribute to the future electricity. . A grid-connected photovoltaic (PV) system, also known as a grid-tied or on-grid solar system, is a renewable energy system that generates electricity using solar panels. The generated electricity is used to power homes and businesses, and any excess energy can be fed back into the electrical grid.
