3.  Solar hybrid systems are power systems that combine solar
power from a photovoltaic system with another energy
source.
 One of the most common hybrid systems being PV diesel
hybrid system, coupling PV and diesel generators, also
known as diesel gensets.
 The diesel generators are used to steadily fill in the gap
between the load and the power generated by the PV
system.
What is Hybrid-PV?

4.  An energy management system can also be included to
optimize the system as the diesel gensets capacity is limited
and the solar energy production is inconsistent. EMS can
ensure fuel saving and optimal operation of the overall
system.
 Battery storages can be used to reduce fuel expenditure, as
the PV system can supply additional energy. Batteries can
also be used to store the excess energy to be used later on.

8. • No wasted Energy
• Uninterruptable Power:
 When the grid fails or when the PV production isn’t enough the system still keep going.
• Hybrid Systems can be programmed:
 With the help of a EMS, hybrid systems can computer control their whole system and balance the available
sources of energy.
• Environment-friendly:
 The use of sustainable resources reduces CO² emissions.
• Not dependent on one source of energy.
• Simple to use.
• Efficiency, low life cycle cost of the components.
• Lower needs for storage.
