1. PV Array: A number of PV panels connected in series and/or in parallel giving a DC output out of the incident irradiance. Orientation and tilt of these panels are important design parameters, as well as shading from surrounding obstructions.
2. Wind turbine: This is installed on top of a tall tower, collects kinetic energy from the wind and converts it to electricity that is compatible with a home's electrical system.
3. Hybrid controller: Control battery bank charge and discharge reasonable and safety.
4. 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 important 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.
5. Inverter: A power converter that inverts the DC power from the panels into AC power.
6. Loads: Stands for the network connected appliances in the building that are fed from the inverter (AC loads), or from the battery bank (DC loads).
