Solar PV Hybrid System

Hybrid system tries to combine multiple sources of power to maximize availability of power. It may source energy from sun, wind or diesel generator and back it up with battery.

1. Multiple sources of generation allows for complementary sources and backup. For instance, when it is sunny out the PV array will charge the battery; if it is cloudy and windy, a wind turbine can charge the batteries
2. Array size and battery bank capacity can typically be reduced and not having to oversize for periods of no sun
3. More complex system design and installation
4. Multiple power sources can increase upfront expenses
5. Wind turbines and generators require regular maintenance.
