In remote areas, both solar as well as wind energy are regarded as the prime source of energy for charging a battery and delivery of grid quality electricity via large capacity wave inverters. Wind turbine can deliver more than 5Kwh of energy every day in those areas where wind speeds lie above 5.4 m/s. A 3.2 KW Whisper 500 wind turbine may produce 16 KWH of energy per day at 5.4 m/s annual wind speed average. When the wind speed lies above the figure of 6.3 m/s average, A 1 Kw wind turbine can deliver 8 Kwh of energy/day.

Wind turbines are considered as economical investment as compared to solar panels of the same capacity. So, in places where wind speeds are more than 5 m/s, you should use a combination of wind and solar power system for optimum investment and getting maximum returns. This combination is referred as wind solar hybrid systems. The topology is successfully satisfying lighting, powering and all the entire electrical needs of villages from many years. It is widely implemented for the purpose of generating electricity, especially in African and Asian countries.

Benefits of using wind solar hybrid systems

Most of the renewable energy experts believe that a stand-alone hybrid system may proffer a lot of benefits over a single generation system. Wind energy and solar power always complement each other. During monsoon season, solar power generation is reduced to a considerable extent due to cloudy skies. But, in the course of same period, the wind speeds are much higher than rest of the year. So, during monsoon, wind turbines generate extra electricity to compensate the loss of solar power. In this way, all throughout the year, the hybrid system maintains the adequate level of power supply. Indeed, wind solar hybrid systems can act as a splendid solution for the complete utilization of renewable energy sources.

At the time, when neither the wind energy generator nor the sun energy resources are available for producing electricity, most of the stand-alone systems deliver electricity energy with the help of batteries or fossil fuels powered engine-generators.
Future aspects

The hybrid system is regarded as a viable economical lighting option for industrialized areas. At present, it has carved out a strong foothold in advanced areas of Asian countries. In recent times, various technological improvements have been seen towards its development. In future, it will definitely expand its viability for other uses.
