With the steady advancement of technology in the rapidly expanding field of solar energy, more and more individuals have started installing solar systems. Of the different types of Solar PGS being installed across the world today, the on-grid or the grid tied system is the most widely chosen.

So what is a Solar On- Grid System?


On Grid System is a Solar Power Generation System (SPGS) where the solar photovoltaic system is connected to the utility grid. The electricity produced by the system is routed to this grid or the electrical service provider from where it is used to run the various appliances. The installation of an On-Grid system is fuss- free and easy to maintain.

The components are:
  1. Solar PV modules
  2. Mounting Structures
  3. Solar Inverter
  4. Monitoring Device
  5. Net Meter

How does an ON Grid System work?

The arrays of solar PV modules absorb the sunlight incident on them and convert them into electricity. It is important to note that the current generated here is DC. A solar inverter then converts this DC current to AC, thus enabling it to power electrical items. This generated electricity is then routed to the grid from where it is supplied for day- to- day use. An important aspect of a solar system is the net meter. A net meter is a device that records the energy supplied to the grid and the energy consumed by the consumer. At the end of each month, the outstanding is recorded and the consumer is provided with an invoice of a credit or debit note.

What are the benefits of On Grid Solar Systems?


  • Zero electricity bills:
  • Though the solar PGS is connected to the grid, the consumer has to only pay for the surplus electricity that he consumes. The invoice generated at a monthly basis determines whether the consumer has any outstanding payments to be made for overconsumption. At the same time, if the consumer consumes less electricity than he has produced, this excess is fed back into the grid.

  • Easy configuration and maintenance:
  • Since out of the three solar PGS (off grid, on grid and hybrid), the grid tied or on grid system has the less number of parts, its installation is simple. The elimination of batteries makes the maintenance of this system easy too.

  • Passive income generation:
  • Being connected to the grid enables the consumer to charge for the surplus electricity that he has generated. Thus, not only does this system eliminate electricity bills, it also helps the consumer avail cost benefits for the electricity that his system generates.
