HY Energy supplied wind solar hybrid street light system for park project in Tabriz, Iran in 2011. HY Energy designed the system according to the project location wind & solar resource condition and specific street light requirement about ground average LUX, illumination distribution, light color temperature etc. The system solution is 400W wind turbine and 240W solar panel to supply for two 40W LED lights working 10 hours per day, battery backup for 5 consecutive rainy and cloudy days, that means the system could keep working if 5days no wind and solar. The lightings have been operation over there for almost 2 years, and system works perfectly.
