A Solar-Wind based Hybrid system consists of the following components connected together to generate power as per the drawing below -
A Solar Panel - This is a string of Photo-voltaic cells connected together to generate a fixed amount of power when sunlight falls on it. We typically place a series of these Panels that is shown as Solar Array in the schematic above, on the roof or any other place that is shade--free. The Solar Panel generates DC or Direct Current.
Wind Turbine - They typically have 3 blades attached to a rotor, and are mounted on a pole at a suitable height to take advantage of wind speeds at greater heights. When the wind blows, it turns the blades producing Electricity using an Alternator that is housed in the Wind Turbine casing.
The Optional Charge Controller and Battery - This is an OPTIONAL part of the Hybrid Plant. These are used in only those cases where there is no connection to the Utility Power, and all of the power requirements of the building are to be only met through Hybrid Power. In such cases the Power generated by the Plant is first used to charge batteries.
The Inverter - This is the HEART of the Hybrid Plant. Put simplistically, it converts the power generated by the Plant to Alternating Current or AC, that is accepted by all Electrical Devices in the Building. Thus, this is what ensures that all existing Devices can be used as is, when we switch to CLEAN & GREEN Hybrid Power.
The Utility Meter - This meter continually measures your Electricity Consumption, and can even count the amount of excess power your Hybrid Plant might be generating beyond what you use, that can be given back to the Utility Grid. Any such power that is given back reduces the amount that appears on your Utility Bill each month.
