Solar Wind Hybrid Systems are powered by sun and wind, in order to guarantee that the power is enough to be charged in the solar battery every day. If on some days there is sunlight but no wind energy, the solar panel charges the battery. If on some days there is wind energy but no sunlight, the wind turbine charges the power to the battery. When both wind and solar energy are sufficient, both charge the battery. At night, the wind turbine can continue to supply power to the system.
What do Hybrid PV and Wind Systems consist of?
a- PV Array: A number of solar panels connected in series and/or in parallel giving a DC output. Orientation and tilt of these panels are important design parameters, as well as shading from surrounding obstructions.
b- Wind turbine: This is installed on top of a tall tower, collects kinetic energy from the wind and converts it to an AC output.
c- Hybrid controller: controls battery bank charge and discharge safety.
d- Battery Bank: can be a single battery or multiple batteries connected together to create, essentially, one large battery of the required voltage and amp-hour capacity. In some ways the battery configuration and capacity are the most critical electrical power decision to make, and a wise choice can help guarantee a steady supply of electrical power as well as a system that is simple to operate and maintain.
e- Inverter: A power converter that inverts the DC power from the solar panels into AC power.
f- Loads: Stand for the network connected appliances in the building that are fed from the inverter (AC loads), or from the battery bank (DC loads).
