On-gird system

An on-grid solar system is a system that works along with the grid,but they do not have batteries. This means that any excess or deficiency of power can be fed to the grid through net metering. The prerequisite for many residential users to choose a grid-connected system is that with relatively stable state gird, as they get a chance to enjoy credit or subsidy for the excess power their system produces and save on their electricity bills.For commercial and industries with large power consumption, the emergence of on-grid solar power generation can help them reduce high power consumption costs and complete energy conservation and emission reduction at the same time.

Hybrids Solar System

A Hybrid solar system is also a system connected to the grid, but it has a battery pack to store electricity. Usually there are two ways to connect to the battery: DC coupling and AC coupling.

Although hybrid power systems are more expensive due to increased battery costs, they allow their owners to maintain lighting when the power grid is interrupted and can even help power load companies save electricity costs by shaving peaks and filling valleys through storage.   

There are obvious differences between off-grid and on-gird solar systems, the most suitable solar system for you depends on your actual electricity needs. Off-grid systems are allowed to be completely unaffected by state grid, but they are usually expensive. The combination of grid-tied system and grid support can save electricity bill, so you never have to worry about not having electricity to power your house or business.
