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.
Difference between off grid and on grid solar panels.
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.
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.
The simple answer to this is that on grid a k a.
An off grid system may require batteries and sometimes a back up generator.
It doesn t cost anything extra to store electricity in the grid.
To balance the grid power during sunlight power is provided by hybrid systems.
When in doubt go grid tied.
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.
This is appealing because you are 100 self sustaining your energy use.
You use battery to stock the energy.
Grid tied systems store energy in the power grid while off grid systems store energy in batteries.
On grid systems are also dubbed grid tie or integrated systems.
For making the right choice we need to understand the key differences between off grid and on grid solar systems.
Off grid solar system the working of the on grid system and off grid system is the same.
This is important for maintenance troubleshooting and protection against electrical fires.
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.
Off grid solar panels system is an independent installation that is not connected directly to the utility feed.
For off grid solar systems one additional dc disconnect is installed between the battery bank and the off grid inverter.
Grid tied solar systems are connected to the main utility power lines called the grid while off grid systems are not.
Being off grid means you are not connected in any way to your grid s power system or utility company.
If the installation produces more electricity than needed then the excess power is sold to the electric company.
In fact batteries are the most expensive part of a solar system.
Off grid solar systems can run independent from the electric grid.
In order to accomplish this they require additional hardware.
On grid solar panels system is an installation connected directly to the utility feed.
But adding batteries to an off grid system is a significant extra cost.
On the other hand off grid solar power systems are those that help you store the solar energy in batteries in case the power grid fails or the grid is not available.
