Summary:
A new energy supply circuit lamp that uses wind energy and solar energy to provide energy to light the street lamp, without the need to connect to the city power grid, and can automatically control the switch and brightness of the street lamp. It can effectively reduce the carbon emissions caused by petrochemical energy, and at the same time can play a good role in popular science and landscape. It is especially suitable for road sections that are inconvenient for city power supply and need street lights.

Configuration: 
Wind turbine, solar panel, controller, inverter and batteries.

Application:
Road lighting, landscape lighting, traffic monitoring, communication base stations, school science popularization, large billboards, remote rural areas and other geographic areas.

System Features:
1. According to the characteristics of wind and solar resources in different regions, reasonably allocate the proportion of wind and solar energy to reduce the cost of the entire system to the greatest extent.
2. Light control to turn on the light, time control to adjust the power, light control to turn off the light, automatic power tracking, high economy.
3. Self-independent integrated power supply system, free from interference from large-area circuit construction, simple process, short construction period, and more convenient maintenance.high power LED light source

FAQ
1:How many cycles full charge&discharge about your battery?
 In 50% discharging deepness, it can be cycled for 1,200 times; in floating charging and discharging status, it can be cycled for 5000~6000 times. 
2.How to Choose the System Voltage  12V or 24V or for normal street Light ? 
We can design the System for 12v or 24v for solar street Light or 220-380V for normal street light .  
3.What's the main difference between mono and polycrystalline solar panel?
production process and cost. Polysilicon technology is more mature since it is an early technology compared with Monosilicon.
