Hybrid PV system

Hybrid photovoltaic systems (Hybrid PV systems), as shown by their very name take the best of both other types of systems – on-grid and off-grid PV systems.

In fact, the hybrid system can be consider as an on-grid system upgraded to include a battery backup: a bank of deep-cycle batteries, which can be charged by both the utility grid and the solar panels. Thus, in the event of an outage, the backup battery can be switched on to provide backup power to the building and in case of failure in the operation of the photovoltaic system, the utility grid can be used for an alternative power supply till the problem is solved.

Also hybrid systems are much more financially advantageous in terms of installation and operation as compared with the off-grid ones, due to the fact that they do not need backup generator and the capacity of the batteries can be downsized.

Hybrid photovoltaic systems are undoubtedly the most flexible type of a photovoltaic system for household or industry, enabling the owners to decide and control in what way and how much energy to produce, where to store it and how and when to use it. In the future, these systems are going to develop greatly and find even better application, especially with the introduction of the concept of the so-called “smart grids".
