A 3kW on-grid solar power plant is a system of solar panels, a grid-tied inverter, and a net meter that generates electricity from sunlight to power a home or small business, reducing electricity bills by feeding surplus power back to the utility grid. The system converts DC electricity from the panels into AC electricity using the inverter. Excess energy not used by the household is sent to the grid, with a net meter recording both energy inflow and outflow, providing credits or calculating charges for the user. This system is ideal for locations with stable grid power and allows for energy independence by utilizing clean, renewable energy.
