An on-grid system implies that your solar system is connected to your utility company’s network. Further, if the user generates excess energy, it can be reverted to the grid-power company. In return, the user can build a credit that can be used to cash out at the end of the billing cycle. This process is known as net metering.
A hybrid power system uses an additional battery system, and is designed to generate some excess electricity during the day which is transferred to the battery systems for storage. The energy stored in the batteries can then be used during the night or when it is cloudy. The key advantage of using hybrid solar panels is that the user is not dependent on grid energy, which means a power failure or an outage would not affect the user in any way.
