This system allows the consumers to use power supply when they are unable to receive power from their rooftop system, especially during night time and days when there is not enough sunlight. This way you can have an uninterrupted flow of electricity through day and night. Thus a well planned rooftop solar system will ensure that you get enough power supply without using the utility grid. In fact, you can earn some credit in your utility account if the excess power generated is fed to the grid for which you get credited a compensation called ‘net metering’.

In off-grid systems, the rooftop solar system is not connected to the main power grid. The system is self-sufficient to run on its own with a battery. The solar power generated from the rooftop solar is fed to an inverter where the direct current is converted into alternating current. This system is very useful when there is no grid supply or when the supply is very erratic with frequent breakdowns. 

  1. Hybrid Systems: 

The hybrid system is a combination of both off-grid and on-grid solar panels. The advantage here is that once a battery is charged the excess energy is fed to the grid which can generate additional income to the consumer.
