An on-grid or grid-tied solar roof-top system is a system that works along with the grid which means that any excess or deficiency of power can be fed to the grid through net metering. Many residential and commercial users are opting for an On-grid solar system as they get a chance to enjoy credit for the excess power their system produces and save on their electricity bills. You will always have power either from the solar system or from the grid. These Type of system do not have batteries.
How on-grid system works?
In an on-grid solar system, solar panels will produce power during the day. This power can either be used instantly or exported to the grid with no backup for power outages. If at any time the system runs out of power, it draws the same from the electricity grid. Hence, a user will never run out of power in this case. Similarly, any excess that is produced by the system is fed to the grid.
The advantage of an on-grid system is that the user will get a credit in his electricity bill for the extra power he sent to the grid. So, his electricity bills will also reduce. Always assess your Home’s Energy Consumption & Solar Electricity Needs. before installing an on-grid solar system.
The light from the sun falls on the solar panels from where DC electricity is generated. This DC from the sun is converted into AC with the help of the inverter, which is then used by consumers in their homes or any commercial Place i.e factory,shop ,School etc. Till this stage operations of any solar system is the same. The main difference is beyond this point. After the electricity that is consumed by us, there can be two routes for the extra energy generated:
- It can be either stored in batteries for use at a later part of the day (off-grid solar system) or
- Fed to the grid (on-grid solar system). Based on the feed-in-tariff rates (tariff fixed by the government, for purchase of the solar power generated from solar plants) in your area, your electricity bill is reduced for the amount of power that you have sold to the power grid

The on-grid system works in sync with the grid, unlike inverters, there is no limitation in the grid-tied system, you can run everything off your home on the grid-tied solar system. For example, a 3kW on-grid system can run 10 kW power.
