When you ask the price, please tell us the following, very key point. 

1.Does the solar LED street lamp power confirm? or do you have luminous requirements?(Brightness of street light required) 
2.Can you tell me where it will be used? ?(According to the local sunshine peak time, we will calculate the configuration of the solar pannel power) 
3 How many work time per day? Does it full output or half output? ( So we can calculate the battery supply)  We usually recommend *0 hours  work time  per day
4.How many back -up days for the lamps ?(When the rainy season coming, how many consecutive rainy days are required to be guaranteed to keep the light working normally) 
5.Do you know the installation  height? and do you need the pole ? (Installation height also determin the brightness)
