India’s WindStream Energy Technologies has developed a wind-solar street lighting system for hilly, coastal and rural areas.
India’s WindStream Energy Technologies has developed a wind-powered hybrid solar LED street light system that produces more energy per square foot than a solar street light.
It recently launched an off-grid lighting system by installing it at the Hyderabad campus of the National Institute of Rural Development and Panchayat Raj. The off-grid LED street light system includes solar modules, wind turbine, back-up batteries, controller and LED.
The battery ensures continuous power supply and covers deficiencies in electricity production from renewable energy sources. The hybrid street lamp is available in 20 W, 40 W and 60 W versions.
“The light-dependent resistor (LDR) of the street light enables automatic switching on/off. The passive infrared (PIR) sensor helps reduce power consumption and increase the autonomy of the light, said Venkat Kumar Tangirala, CEO of Windstream Energy Technologies. pv magazine. “With winch installation, the panel can be lowered, cleaned and rolled into place.”
