Hybrid solar systems combines the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage.
A hybrid solar system generates power in the same way as a traditional grid-feed solar system but can also store energy in a battery for later use. This enables most hybrid systems to also operate as a backup power supply (UPS) during a blackout.
A hybrid system enables you to store the solar energy generated within a battery which gives you the ability to use it when you're home during the evening (when the cost of electricity is typically at the peak rate). Since the cost of peak electricity in some countries is four to five times the solar feed-in rate a hybrid system can greatly reduce your electricity costs.
