FAQ: 
1. What are the information you should give us to best customize our solar systems?
(1)The sunshine hours per day or the exact city where the street lights will be installed in. 
(2)How many continuous rainy days in the raining season there? It matters because we
have to make sure the systems can still work in 3 or 4 raining days with little sunshine.
(3) The accurate pot of the installation.

2. What is the typical maintenance schedule for a solar system?
There is no regular maintenance required for a solar system. However, it is helpful
to keep the solar accessories clean, especially in a dusty climate.

3. What happens if there are cloudy days?
Electrical energy is stored in the battery each day, and some of that energy is used to operate
the systems at rainy or cloudy days. Generally, the system we design would allow the battery operate the system
for four nights without charging. This means even after a series of cloudy days, there still
will be plenty of energy stored in the battery to power the system. Also, the solar panel
will continue to charge the battery (although at a reduced rate) even when it is cloudy.
