Difference Between Off Grid And On Grid Solar Panels

To balance the grid power during sunlight power is provided by hybrid systems.

Difference between off grid and on grid solar panels.

In order to accomplish this they require additional hardware. On grid systems are also dubbed grid tie or integrated systems. An off grid system may require batteries and sometimes a back up generator. Off grid solar panels system is an independent installation that is not connected directly to the utility feed.

Being off grid means you are not connected in any way to your grid s power system or utility company. In fact batteries are the most expensive part of a solar system. This is important for maintenance troubleshooting and protection against electrical fires. For off grid solar systems one additional dc disconnect is installed between the battery bank and the off grid inverter.

The simple answer to this is that on grid a k a. It doesn t cost anything extra to store electricity in the grid. While an on grid system doesn t. An off grid solar energy system is not connected to the utility grid whereas an on grid aka grid tied solar energy system is connected to the utility grid.

Grid tied solar systems are connected to the main utility power lines called the grid while off grid systems are not. Off grid solar systems can run independent from the electric grid. This is appealing because you are 100 self sustaining your energy use. Off grid solar system the working of the on grid system and off grid system is the same.

If we now after the failure of supply from the electricity board we have to face the dark situations after having a solar system too. If the installation produces more electricity than needed then the excess power is sold to the electric company. Dc power generated by the pv panels is fed into a charge controller which regulates the charge instead of the utility company s computer controlled grid. When in doubt go grid tied.

However there are disadvantages because off grid systems require you to purchase back up battery which can be expensive bulky and not very environmentally friendly. The only difference is the battery backup. On grid solar panels system is an installation connected directly to the utility feed. You use battery to stock the energy.

On grid systems send excess power generated to the utility grid when you are overproducing. On grid solar systems generate power only when the utility power grid is available and directly connected to the utility feed. But adding batteries to an off grid system is a significant extra cost. It is used to switch off the current flowing between these components.
