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.
ON-GRID SOLAR POWER SYSTEM WORKING PRINCIPLE
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 Solar Start 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.
