SolarMills are most valued integration of wind and solar energy, the technology is future of green energy: Mr. Venkat Kumar Tangirala, MD, WindStream Energy Technologies

The Mumbai International Airport, in its quest to reduce carbon footprints and to explore the possibility of utilizing wind energy, introduced the vertical axis wind turbine (VAWT) and sold PV hybrid (solar mill). As quoted by Hindustan Times, a Chhatrapati Shivaji Maharaj International Airport (CSMIA) spokesperson claimed that this initiative undertaken by the airport aims to reduce dependence on conventional electricity, which propels its journey towards ‘net-zero’ emission.

 

Windstream Energy Technologies India Pvt Ltd has developed this first-of-its-kind, fully integrated, hybrid renewable energy product which harnesses solar and wind energy combined to generate electricity. In a candid chat with Mr. Venkat Kumar Tangirala, Managing Director, WindStream Energy Technologies India Pvt. Ltd., The Quotes discussed wide range of topics including related to SolarMills.  

 

SolarMills are a unique option as an adaptable technology to produce green energy. Kindly shed some light on what sets SolarMills apart from any other product in the market including its benefits to the common public?

 

With the large bandwidth of advantages ranging from being a simple construction, scalable, modular, environmentally sustainable off-grid or on-grid operations feasible, more energy density per square feet generating system at the lowest cut-in and max cut-out wind speeds compared to any of the other renewable energy generating systems such as solar, biomass, and hydro. Adaptability and acceptability of the technology depend upon varied applications that the system can be used in economical cost of operation, ease of scalability and return on investment.
With 24 hours power generation capability out of the wind source, there is prolonged storage of power in the battery due to the continuous power generation, facilitating smooth battery charging and discharging, thus increasing the life of the battery and thereby the reduced costs through solar generation is for a limited period. Based on the wind velocities, the system efficiency and output pattern can be designed for a designated Site.
 


The system is based on the installed generation capacity; the estimated Return on Investment will be as low as 21/2 years to a maximum of seven years, while the power generated during the balance of the years of the life of the system will be at no cost except for the repairs and maintenance or any such accidental or incidental expenses.

 

Windmills are generally used by big corporates and require enormous land, technology and financial expenditure. So how is SolarMills (vertical axis wind turbine (VAWT) and sold PV hybrid (solar mill) emerging as a feasible option for the common man in the Country?

 

Observing the trends in the chargeable cost per unit of electricity power consumed, which has metamorphosed into dynamic pricing of units, both for domestic and industry, with the thermal generation being discouraged for negatively impacting the environment due to excess release of carbon emissions and more importantly, fossil fuels usage being discouraged with the assumption that non-renewable fuels will not last long.

 

World Global Forums such as Paris Agreement and others such as enforcing the countries to achieve Net Carbon Zero by 2050. It is becoming imperative that dependency on renewable power shall be predominant. Installing low wind systems would entail individual customers an affordable power source as it can be installed on surfaces requiring small areas and can be customized to the individual home requirement with high-density power generation.
