Understanding On-Grid Solar Systems. On-grid solar systems, also known as grid-tied or grid-connected systems, are connected directly to the local utility grid. This means that electricity generated by the solar panels can be used to power your home or business, while any excess electricity can be fed back into the grid for others to use.
These installations also provide the capability to feed back into the grid. The principle of grid-connected PV. A grid-connected PV installation consists of three components: energy generation, power conversion and energy utilisation.

Grid Tied Solar System • A grid-tied system is a basic solar installation that uses a standard grid-tied inverter and does not have any battery storage. • This is perfect for customers who are already on the grid and want to add solar to their house. These systems can qualify for state and federal incentives which help to pay for the system.
Working Principle of Grid Connected PV System • Whenever the sun shines (and even in overcast weather), the solar cells generate electricity. The grid connect inverter converts the DC electricity produced by the solar panels into 240V AC electricity, which can then be used by the property/household.
However, when the PV plant is connected to the grid, special attention has to be paid to the reliability of the system, the power quality, and the implementation of protection and grid synchronization functions.
Unlike other solar system types, most models of a grid-connected PV system do not require additional batteries; and hence, are cheaper. A grid-connected PV solar system can be installed in vacant roof space without requiring any additional land. It's quite reliable.
