On-Grid or Utility Interconnected System

This is the most common type and connects the system to the electrical grid and allows the home owners to use both – the grid’s electricity and solar energy. The unique feature of this system is that when the residents do not need power or there is excess of it, the solar panels automatically send the excess electricity produced back to the grid, thereby making it useful somewhere else. On the flip side, in the event that the solar panels are unable to produce enough power for the users (due to cloudy and stormy days, night time), the users get their electric supply from the grid.


This system works two-ways – the supply of electricity can flow from the grid to which it is connected to the user’s home and from the user’s home to the grid. This feature makes the on-grid solar system affordable and highly useful. The solar panels, installed on the user’s home are ‘tied’ to the grid. These panels generate electricity when the sun is shining brightly and this electricity is then ‘sent’ to the electrical distribution panel in the home for use. Any surplus power is then, sent back to the grid and this instantly lowers the meter reading of your home. The power charges are only as much as the home uses and in addition, the grid acts as the ‘store’ for the excess power the on-grid solar power system generates.

Let us look at how this system works in a few easy steps:

Step-1: The solar panels convert sunlight into electric energy, which is Direct Current (DC). This current is then sent to an inverter.

Step-2: The inverter converts this DC to Alternating Current (AC) since households are only equipped to use AC. The grid tied inverter additionally regulates the amount and voltage of electricity fed to the household since all the power generated is mostly much more than a home needs or can handle.

Step-3: This ‘converted’ power supply is then used by homes through the main electricity distribution panel. Your home now has access to clean and green electricity, which makes you a contributor towards a cleaner and more sustainable environment.

There could be worries about how the home will receive power when the sun is not shining – that is the benefit from having the system ‘tied’ to the grid – your home receives non-stop power irrespective of the weather.

The other great benefit of this system is that when there is sunlight, your electricity meter does not move at all! The solar panels generate the power and the inverter feeds the electricity to the main supply and since this is the electricity your home is using, there is none being taken from the grid and hence no charge.

Electricity is a finite resource and as the number of users rise, its cost will rise. The cost you incur on installation of this system is usually recovered within a short span of about 3 years since the savings on electricity are huge. We at With JANGID Solar Energy Pvt. Ltd. wish to transfer this control and ‘power’ to all by providing the best solar power systems, that are supported by excellence in customer service and in-depth knowledge of our experts.
