An on-grid solar system, also known as a grid-tied solar system, is a solar energy generation system that is connected to the main electricity grid. It is designed to supplement the electricity supply from the main grid by generating electricity from the Sun, which is then fed back into the grid for use by other consumers.

An on-grid solar system typically consists of solar panels, an inverter, and a metering system. The solar panels convert sunlight into DC electricity, which is then converted into AC electricity by the inverter. The AC electricity is then fed into the main electricity grid for use by other consumers. The metering system measures the amount of electricity generated by the solar system and the amount of electricity consumed from the main grid, allowing for accurate billing and monitoring of energy usage.

Overall, on-grid solar systems are a promising solution for reducing electricity bills and promoting sustainable energy generation in areas where the main grid is reliable and accessible. By supplementing the electricity supply from the main grid with clean energy generated from the Sun, on-grid solar systems can promote environmental sustainability and reduce the reliance on non-renewable sources of energy.
