A hybrid system brings the best of both worlds and is a combination of an on-grid and off-grid solar system. Hybrid systems have a battery backup which helps store the generated energy. What differentiates hybrid systems from off-grid systems is that, once the battery is fully charged, any excess power generated which is not being utilised will be fed back to the grid and the you will get suitably compensated. A hybrid system can also have other sources of energy producers, such as Diesel Generator (DG) or Wind coupled in the system.
