Comparison between Hybrid and OFF-Grid Solar System

Solar energy systems have come out as a practical and the most beneficial solution to the electricity problems and environmental crises. Now there are a variety of solar systems available in the market with diverse features and specifications. 

To categorize, these different solar systems can be grouped into three classes, namely; On-Grid solar systems, Off-Grid solar systems and Hybrid solar systems. We have previously covered the differences between On-Grid and Hybrid solar systems and in this blog, we will see what makes Off-Grid systems different from Hybrid solar systems.

Off-Grid Solar System in Pakistan

In remote areas where there is no grid connection available, off-grid solar systems are the most practical solutions available. Off-grid solar solutions are reliable for the agricultural and defense sector since they don’t require a grid connection. This system is good in the way that it provides backup when there is no grid electricity available. All these qualities make off-grid a more practical solution as compared to an on-grid system in remote areas.

Hybrid Solar System in Pakistan

The on-grid system is cost-effective and allows you to sell the surplus power, and the off-grid solution permits you continuous electricity during power outages. The cons of both systems urged the manufacturers to invent a system that could provide dual functionality. The outcome was a system that had all the prominent characteristics of both on-grid and off-grid systems and could be utilized as both. The crossover properties prompted the structure to be named the Hybrid Solar system.

Comparison between Hybrid and OFF-Grid Solar System

Feature	Off-Grid	Hybrid
GRID CONNECTION	These systems are not connected to the grid and can function without connection to the grid.	These systems are directly connected to the grid and can also perform their tasks without connection to the grid.
BATTERY	These systems cannot work without battery connection as they are not connected to the grid and require batteries to save excess electricity which can be used later on.	Batteries are optional for hybrid systems. They are an added feature which can be used at any time. Hybrid systems work without and with the batteries as well. It is up to the user how to use them.
NET METERING	Without a connection to the grid, net metering cannot be used. The off-grid systems do not offer a net metering facility.	Hybrids are a mix of off-grid and on-grid systems and perform both the functions. Thus, the net metering option is available with the hybrid systems
BACKUP GENERATOR	Unlike grid-tie systems, these systems essentially require batteries to be able to perform their operations and so backup generators also become a necessity.	These systems if are connected to batteries would definitely require a backup generator as well.
ADVANCEMENT IN TECHNOLOGY	This technology is comparatively old yet innovations have kept it in the market.	This is the latest generation of systems made to perform both off-grid and on-grid functions. This eliminates the cons of these systems.
RELIABILITY	These systems are moderately reliable and somewhat difficult to control. The batteries may also require maintenance thus making them less dependable.	The maintenance of batteries makes it a hassle; however, the overall performance of these system makes them extremely reliable since they can perform both on-grid and off-grid functions.
PERFORMANCE DURING A BLACKOUT	These systems have batteries attached to them which store the electricity in them. The batteries provide support and backup when there is any kind of grid failure or blackout situation. It is worth mentioning here that the backup will be dependent upon the size of batteries you have installed.	They may or may not be attached to batteries so whether they can provide you with backup in a blackout situation depends upon the way the user is utilizing their potential.
MAINTENANCE	Off-grid systems also do not require maintenance every other day, however, they need more frequent checkups and servicing when compared to grid-tie systems.	Hybrid systems perform the heaviest operations if they are performing as both on and off-grid systems so they require most frequent maintenance and servicing.
SIZE and COVER AREA	Off-grid systems are compact in size, however, the addition of batteries and the backup generator makes the whole system a big one and so usually a spacious area is needed to install them.	The hybrid systems if have batteries and backup generator to perform both on and off grid functions, occupy a lot of space. Otherwise, these systems are easy to install as a grid-tie system.
USAGE	These systems become expensive because the solar batteries that are usually required with them are very expensive.	These systems are best to be used for commercial and residential purposes. However, they may not be ideal for industrial purposes as the batteries would be very costly.

Off-Grid Solar System Price in Pakistan

The off-grid Solar System Price in Pakistan is lower than Hybrid solar system. The reason is that the batteries are the only more expensive parts in an off-grid solar system and there is no net metering connection, so that cost is saved. However, it is still higher than the on-grid solar system in Pakistan.

Hybrid Solar System Price in Pakistan

Hybrid solar system price in Pakistan is higher as compared to the off-grid and grid-tie solar system, mainly because to offer the cons of both the systems, i.e. the parts and features of both are required. You need net metering as well as batteries to fully enjoy your hybrid system.

Which System Should You Choose?

It depends mainly upon your choice. If you are fine with only net metering then a grid-tie solar system is perfect. In case you are looking for a more reliable & robust setup and lesser bills, then hybrid system is the best choice. However, you need to invest carefully because the batteries and the inverters in a hybrid system both will need to be replaced in a time period of 8-12 years thus you will need to invest double the money again. If backup is the only priority and you don’t need net metering, off-grid is the best option, especially if you are located in a remote area.
