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