●What information needed for desgin

Generally, SunMaster needs those questions answered.

1) The site location for solar radiation data
2) How many continuous rainy days in the raining season there? (It matters because we have to make sure the light can still work in 3 or 4 raining days with little sunshine)
3) The brightness of LED lamp
4) Working time of solar light every day(10 hours, for example)
5) The height of the poles, or the width of road
6) It is best to offer the pictures on the locations where the solar lamps going to be installed.

● Does the solar light turn on and off automaticlly?

SunMaster's solar controller uses a photocell and/or timer to control when the light will turn on, when the sun goes down, and to turn off when the sun  comes up.  The photocell detects when the sun comes down and when the sun comes up again. SunMaster can make the lamp last anywhere from 8-14 hours, and this varies on the customer's needs.

The solar controller utilizes an internal timer that is pre-set for a specific number of hours to determine when to switch the light off. If the solar controller is set to leave the light on until dawn, it determines when the sun rise (and when to switch the light off) by means of voltage readings from the solar panel array.

●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 light at night. Generally, we design your system so that the battery will operate the light for five nights without charging. This means that, even after a series of cloudy days, there will be plenty energy in the battery to power the light each night. Also, the solar panel will continue to charge the battery (although at a reduced rate) even when it is cloudy.

●What is the typical maintenance schedule for a solar lighting system?

There is no regular maintenance required for a solar lighting system. However, it is helpful to keep the solar panels clean, especially in a dusty climate.

●Do I have to charge the Batteries?

Batteries are shipped 85% charged. The batteries will be at 100% charged within two weeks of proper operation.
