Telangana-based WindStream Energy Technologies has introduced a hybrid wind-solar-powered LED street light system that generates more energy per square foot than a solar street light. It launched this innovative off-grid lighting system recently by installing it at the Hyderabad campus of the National Institute of Rural Development and Panchayat Raj.
The off-grid LED street light system comprises solar modules, a wind turbine, backup batteries, a controller, and an LED. The battery ensures a continuous power supply and covers any deficiency in power generation from renewable energy sources.
The hybrid street light is available in 20 W, 40 W, and 60 W.
“The light-dependent resistor (LDR) in the street light enables an automatic switch on/off. Passive infra-red (PIR) sensor helps to reduce power consumption and increase the autonomy of the light. The winched setup enables the panel to be brought down, cleaned, and rolled up to its position,” Venkat Kumar Tangirala, managing director at Windstream Energy Technologies, told pv magazine.
“The design guarantees low-cost operation and less space consumption with the flexibility to be retrofitted for the existing solar street light.”
