An on-grid solar system is a type of solar energy system that is connected to the main electricity grid. This means that any excess solar energy generated by the system can be fed back into the grid and used to power other homes or businesses. On-grid solar systems typically consist of solar photovoltaic (PV) panels, an inverter, and a charge controller. They can range in size from small residential systems to large commercial and industrial systems. The main advantage of an on-grid solar system is that it provides a reliable source of clean, renewable energy that can help to reduce reliance on fossil fuels and lower electricity bills.
