Innovative off‑grid lighting merges solar and wind power
The Indian company WindStream Energy Technologies is launching an innovative solution that combines photovoltaics with a wind turbine, designed to power street lighting systems.
WindStream Energy Technologies, a startup from India, has introduced a hybrid street lighting system that merges solar energy with a wind turbine. This system is tailored for hilly, coastal, and rural areas.
Combining solar and wind energy
According to information from pv-magazine India, the Telangana-based company has successfully combined solar energy with wind turbines to generate power for street lighting. This solution is off-grid, meaning it operates independently of the electricity grid, storing excess power for periods when it is not being generated.
The system developed in India includes solar panels, a wind turbine, batteries, a controller, and an LED street lamp.
How does the Indian startup work?
The system is offered in three versions with power outputs of 20, 40, and 60 watts.
The photoresistor in the lamp allows for automatic switching on and off of the lighting. The passive infrared sensor (PIR) reduces energy consumption and increases the autonomy of the lighting. With the hoist, cleaning the panels and resetting them is easy, states Venkat Kumar Tangirala, managing director of WindStream Energy Technologies, in an interview with pv-magazine.
He also emphasizes:
This project is characterized by low operating costs and reduced space requirements, as well as ease of integration with existing lighting that uses solar energy, he adds.
