What Is the Difference Between Off-Grid and On-Grid Solar Energy

  • by

Access to electricity
An off-grid system has no outside source to access electricity. It can only have power when the system is producing it. This means there will be access to electricity only when there is sunlight. To have access to electricity at all times, an off-grid system must have a massive battery backup that can store electricity produced during the daytime and then supply it when the system is not producing electricity. If there is a higher electricity demand, a generator may also need to be connected to the off-grid system.
An on-grid system is connected to the utility grid, making access to electricity easier. You can enjoy electricity even when your solar system is not working or producing sufficient electricity to meet your needs. Being connected to the grid helps you to enjoy electricity at all times, whether you are producing it or not. However, in case of a utility power failure, your on-grid system will also seize to operate.

Grid power outages
If we compare on-grid and off-grid solar systems in terms of power outages, off-grid seems more beneficial. Since this system operates independently, it does not get affected due to power cuts. 
In case of a storm or other conditions that result in a power cut, the off-grid panels continue to function. 
Although an on-grid power system provides sufficient power every time of the day and night, you will have power outages if the grid goes down. 
If you want to avoid such situations, you can buy a battery bank. This system is known as a hybrid system.

Power generation
An off-grid system produces electricity according to the sunlight it receives throughout the day. 
During noon time, when the sun’s rays have maximum intensity, the system produces surplus electricity. You need the proper equipment to make appropriate use of this excessive power.
The off-grid systems produce extra electricity during the day to provide sufficient power when it gets dark. Therefore, it is crucial to have powerful batteries to store the energy being produced. 
Similar to an off-grid system, a grid-tied solar system also produces excess power when solar cells receive enormous amounts of sunlight during sunshine hours. 
However, in this system, the surplus power is transferred to the commercial grid. A bi-directional meter keeps a record of the units generated and consumed. 
In this system, there is no requirement for a battery backup. It uses a net metering system which compensates the user’s account for the amount of surplus power transferred to the grid. It ensures that the customers pay only for the extra units they use from the grid.
