Hybrid systems are usually a combination of photovoltaics with wind turbines and/or generators running on diesel or biofuels. Power generated by the PV array during the day is stored in the battery bank through an energy manager, which controls the complete system.
Hawkspreys' hybrid systems make optimal use of sunlight and wind speeds - the two main resources readily available in the South Asian sub-continent. When the solar resource is low during the monsoon, the wind is quite strong and vice versa. The resultant hybrid system thus offers an optimal solution at a substantially lower cost. It is ideal for electrification of remote villages in India.
