Q. Can I have a sample order for solar powered street lights?

A: Yes, we welcome sample order to test and check quality. Mixed samples are acceptable

Q.How long does the solar power can be stored?

A:Solar power of the integrated solar street light can be stored for 6 months after the batteries are full charged. Please examine, and charge periodically after long time transportation to prevent damage.

Q: How to Choose the solar powered street lights System Voltage ? 12V or 24V or for normal street Light ? 

A: We can design the System for 12v or 24v for solar street Light or 220-380V for normal street light. 

Q: How many cycles full charge&discharge about your battery?

A: 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.

Q. How to control the luminance of the solar powered street lights?

A:Our solar street light adopts Microwave sensor control & brightness sub-regulation. Here we especially introduce the brightness sub-regulation. Use a computer system to set the brightness according to the time change. For example, from 6:00p.m. to 12:00p.m., 100% brightness; from 0:00a.m. to 06:00a.m., 20% or 30% brightness. In that way, this new product can instead common LED street light.

Q. What is the mounting height?

A: We suggest the solar street light of 20W, 30W, 40W for 3-5m, the solar street light of 50W, 60W, 80W for 6-8m.

Q. What is the distance?

A: For the distance, we suggest the solar street light of 20W, 30W, 40W for 10-15m, the solar street light of 50W, 60W, 80W for 20-25m.
